Post by: ChrisB on March 20, 2007, 03:54:06 PM
Ian - I told you I had a photo of the Avalanche erythronium in my calendar from BC, but now I come home, they called it 'white fawn lily'. Is it the same?

Hello Chris,
here my first Erythronium for this spring
Erythronium caucasicum
Erythronium dens-canis ssp.niveum

Hi Chris, thanks for sharing the picture with us.
What you show  is not the avalanche lily which is Erythronium montanum but Erythronium oregonum.
Here is a picture of E. montanum, it has plain green leaves while oregonum has brown patterns on its leaves, there are also differences within the flower which lets me identify your picture.

Thanks Ian, much appreciated.  It says in the caption that it was taken in Uplands Park, Greater Victoria, in case it is of interest.  Sure do wish they would give botanical names to the plants they picture, they do for the creatures....

Thanks again,  Christine

Good idea to start up an Erythronium thread !
Beautiful pictures everybody.

Here's what I bought at the Harlow show from Aberconwy nurseries :

Erythronium multiscapoidium cliftonii

Ah yes, Luc, I got one too.  Has identical flowers.  Very nice.  I'm hoping it clumps up nicely.  Ian said I should put it in the garden rather than keep it in a pot.

I'm going to get more of these, I really like them.  Now I've been to Ian's talk its got me very interested in them.  I'd love to see them in your garden Maggi, but its a bit far to travel.  The pictures of them at the talk were wonderful.  Where is a good place to look for them?  Don't want to get poor quality ones, and as I'm getting older, I  can't just rely on seeds, they take too long to become flowers.  I need tubers/corms or whatever they are so I can enjoy them straight away.  Maybe I'll look at the nurseries at Hexham.....

Erythronium season has begun here in Oregon too.  Erythronium hendersonii is one of the first to come in to flower, and also does really well in our area, as long as they don't receive summer irrigation.  This patch was grown from seed, the first flowers blooming in the third year, many flowers in the fourth year.  So even though it takes patience, seed is the way to go if you want a nice big patch.

Title: Re: Erythronium
Post by: Ed Alverson on March 23, 2007, 10:44:46 PM
Erythronium revolutum is also starting to flower here.  Actually, the plants in my garden are just coming up, this photo was taken at the Hendricks Park Rhododendron Garden here in Eugene.  Erythonium revolutum is distinguished from E. hendersonii by the pink rather than lavender flowers.  Also, the stamen filaments are flattened in E. revolutum, rather than thread-like in E. hendersonii.  Erythronium revolutum grows naturally in high rainfall regions near the coast, so it survives much better in parks and gardens that are irrigated in the summer - many other western NA Erythroniums will not tolerate summer water.

If you look carefully at this photo, you can see that the leaves are clumped because of the production of offsets from corms.  I'm not sure if this is a result of growing in garden conditions (good soil, weeding, extra water, etc.) or possibly an indication that these plants are progeny of a selected form or hybrid of E. revolutum that was selected because of its vegetative reproduction capacity.

Great to have you in the Forum Ed. It is interesting because the first of our E. hendersonii is just opening as well, we have no revolutum in flower yet but some are in bud.

Gene
I have no trouble germinating E. montanum I have grown it many times from collected seed and now get a regular supply of seed from our own garden. It is an interesting erythroniums as it is always the last to appear and flower but the first to set seed and go dormant - obviously adapted to a very short growing season in its habitat.

I've just come back from a really quick trip to the Siskiyous to collect some Trillium rivale pollen. (The Siskiyous are an East/West running mountain range along the Oregon/California
border with many endemic plants.)

Erythronium citrinum was in flower in one spot in the Illinois River valley where
it is always early.  Here is a typical flower:

All the plants I photographed were growing in a small area about the size of a city lot.

This group has one flower tinged pink, and there was another pinkish flower nearby.
There are no pink erythroniums within bee flight, unless a bee hitched a ride on a
vehicle.

Hi Diane,

Saw one just like it at the Hexham Show today.  It didn't win anything, but it is pretty, mine looks very similar too.  I'm hoping it will clump up, Ian said i should plant it out in the garden, but not yet, not while I can still enjoy it in its pot.....

What great plants !!!!

Here's a humble contribution :

1) Erythronium tuolumnense - clum needing to be thinned out a bit + some potash to get more flowers     
    I guess ?
2) close up
3) Erythronium revolutum - obtained from the BD himself last year  :D !
Title: Re: Erythronium
Post by: Paul T on April 04, 2007, 03:09:51 AM
Luc,

Lovely!  C. tolumnense responds very well when given some high potash bulb food.  My big clump had very few flowers until I fertilised it.... the following season there were lots.  I forgot last year unfortunately, after a couple of years of fertilising, so I don't expect many flowers this year.  I have fertilised each time, with a slow release bulb food, as they broke the surface, so that they had food throughout the growing season whenever they wanted it.  Good luck.

Hello,
 
 Here are a few of the lesser known and seen eastern NA species of Erythronium. Both of the 'other' yellow ones are far better than E. americanum which sends out numerous droppers each year. Erythronium umbilicatum never produces droppers, but immature E. rostratum does produce 1-3 per bulb. E. rostratum has the added bonus of outward facing flowers that follow the sun with a light to heavy fragrance in some forms. Erythronium rostratum has a beak on the seed pod, and umbilicatum has an umbilical cord that dries about the time the seed begins to ripen (photos soon). In habitat that is about the second weekend in April. Erythronium mesochoreum is a better version of E. albidum that flowers reliably every year with no droppers. It sometimes has a heavy fragrance similar to Lilium speciosum. It can be found in the prairie in extremely large numbers sometimes and also dry oak woods.

 1) E. mesochoreum with yellow/cream margined leaves.
 2) E. rostratum colony in Louisiana, much nicer garden plants (and more fragrant) than those in the western Ozarks.
 3) E.rostratum, Louisiana, clonal with extra petals/tepals
 4) E.umbilicatum clump from South Carolina
 5) E.umbilicatum from SC, & seedlings with Trillium reliquum
 6) E.umbilicatum, SC profile

Great natural shots, Aaron. Good to have you with us!
Ian will be so pleased to see these on the forum!
Doesn't the E. umbilicatum in your fifth picture look fantastic paired with the Trillium?
Title: Re: Erythronium
Post by: Ian Y on April 05, 2007, 09:29:18 AM
I am so pleased to see these pictures Aaron, I have been trying to understand the Eastern American Erythroniums for years. My trouble is that I am mostly growing plants from cultivation as I rarely see seed of wild origin offered but I do have a few forms of E. americanum from wild seed.
It is very difficult to see the taxonomic differences in these cultivated plants, perhaps they have further hybridised in gardens adding to my confusion.
The rostratum is especially beautiful and I grow nothing like that - is it always free of the brown spots seen on the flowers on the other species?
I cannot wait to see more pictures from you, how I wish I could be there with you to study them in habitat.
Title: Re: Erythronium
Post by: Paul T on April 05, 2007, 01:12:47 PM
Aaron,

Beautiful pics.  I've never heard of a variegated Erythronium before.  Very cool.   The E. umbilicatum in particular is lovely to see.  I have seen this in books and it has become one of those "holy grail" type plants for me.  I hope to find it here in Australia or find seed somewhere one day.  The lovely leaf markings and the yellow flowers with reddish reverse really appeal to me, and I just LOVE Erythroniums.  That and E. japonicum are two I have been wanting for ages, and I was given some seed of the latter last year (by one of our lovely SRGCers) and I am waiting to see if it germinates for me this year.  If it does then I figure most of you will hear the cheer, even if you ARE on the other side of the world.  Of course it is a long way from germination to actually flowering it, but the germination bit definitely does help a lot!!!! <grin>

Again, wonderful pics.  Thanks for taking the time to post them.

First Galanthus of the year was open today.... Galanthus reginae-olgae.  I look forward to the first snowdrop every year.  This year they are a bit over a week earlier than usual (they're usually around the 14th of April).  So nice to see them in flower, even if it is "just" the autumn ones.  I love ALL of them.  ;D
Title: Re: Erythronium
Post by: Afloden on April 05, 2007, 03:32:52 PM
Hello,
 
 I have promised some of the seed (if it ripens) to person in AU, so if I have extra, I could send some your way. There is an online document on seed germination that has been mentioned on T-L, and here I believe at some point. They germinate like grass for me. I'll send seedling pics later after school. Sadly the only western species I grow is oregonum. I have never had any from Ratko germinate, but it was many years ago that I last tried. I'll let you know how much seed I get. I am always willing to trade for things. Hyacinthaceae (Muscari, Bellevalia, Hyacinthella) are a favorite group as the are the Narcissus sect. Pseudonarcissus. And then Polygonatum, Smilacina/Maianthemum, Epimedium......

 The variegated one was found as a seedling that finally flowered three years later. I wish it had been albidum though, a carpet of that foilage would have been nice.

 I just checked on the Ozark forms of rostratum and found that they are triploid and put more into vegatative growth rather than flower production (Carr, Castanea 51:22, 73-87, 1986). The Louisiana and Texas forms are diploid and the colonies I saw last year had 75% of the plants flowering in most cases. Some were higher. From Hardin's paper on the eastern yellow species he says that there is never spotting on rostratum, but I double check my pictures of those in the garden and habitat. I seem to recall a slight amount of spotting on some.

 The capsules on the species are E.rostratum = beaked, E.americanum = round, truncate, or apiculate, E.umbilicatum
= indented (umbilicate). Hope this helps. I can send a copy of Hardins paper by post.

 Yes, Trillium look good with so many things. I grow so many Trillium and other things also. I am a hopeless addict of plants, both cultivation and study.

Post by: Ian Y on April 06, 2007, 10:02:18 AM
Thanks for that further information Aaron and the offer of the Parks and Hardin Paper but I have it already.
My problem is that I have read it over and over and it does not make sense with the plants I grow leading me to believe that I do not have the correct plants and or that they have further hybridised in cultivation. Many of the diagnostic features they use such as the end shape of the seed capsules seems to vary from year to year in the same plants I have depending on climate and fertility.
I would be delighted to swop seeds of anything I have to get some wild sourced seed of the Eastern erythroniums, I can send you western seed as I grow most of those species.
Title: Re: Erythronium
Post by: Ed Alverson on April 06, 2007, 07:30:00 PM
Ian, I'm sure you would find it easier to identify your yellow eastern American erythroniums if you had the latest model of the RonCo automatic chromosome counter (it slices, dices, and counts chromosomes!). 

Serously now, the complicating factor is that E. americanum, the most familiar species of this complex, is an "allotetraploid" species that essentially combines the two genomes of the (typically) diploid E. rostratum and E. umbillicatum.  Aaron's great photos really show clearly how different E. rostratum and E. umbillicatum are from one another. 

The fomation of E. americanum came about when, some time in the past, E. rostratum and E. umbillicatum came together and hybridized, and the hybrid doubled its chromosomes to become a new fertile species, which we call E. americanum.  If you look at the distribution map in Parks and Hardin, you will see that the ranges of E. rostratum and E. umbillicatum are basically separate at the present time, E. umbillicatum occurring in and east of the Appalachians, E. rostratum occurring to the west.  However, the species could have come together in the past as plants migrated in response to climate changes.

This pattern of "reticulate evolution" is actually fairly common in the plant kingdom (Erythronium elegans and E. quinaultense arose in the same way).

Such species of hybrid origin typically express their morphology as intermediacy between the two parents, but in actuality the appearance of a particular morphological character may range from nearly like one parent, to nearly like the other parent.  Furthermore, over time there may be silencing of duplicated genes (remember, E. americanum has four copies of each chromosome, rather than the 2 copies found in a basic diploid species; often these redundant genes tend to go silent over time) that can further affect expression of morphology.

It is likely, actually, that this process of hybridization and chromosome doubling has happened multiple times over the past cycles of glacial and interglacial periods, so the species that we call E. americanum is a mixture of different populations with separate hybrid origins.  So variation in E. americanum may be due, in part, to the differing genetic influences of its parents.

Add to the the possibility that when true plants of the E. rostratum and E. umbillicatum are grown in gardens along with E. americanum, the resulting seed may actually be hybrids with E. americanum (unless special precautions are taken to prevent hybridization), I can see how your identification difficulties might come about.  Like you say, the best solution is to grow plants from correctly identified, wild collected seed.

In the mean time, you could analyze each of you yellow trout lily accessions according the the entire list of characters presented in the table in the Parks and Hardin paper, and I suspect that if you considered all of the flower and fruit characters together, you should be able to put a species name on each clone - without having to fork out all that cash for the RonCo automatic chromosome counter.
Title: Re: Erythronium
Post by: Ed Alverson on April 06, 2007, 07:49:51 PM
My apologies if the previous post was too  much technical detail.  Hopefully I can make up for it with some photos of wild-growing Erythroniums from our area.

These photos are of a nice patch of the form of Erythronium oregonum that is typically found here in the Willamette Valley.  I call it ssp. leucandrum because the tepals are cream-colored or even a bit yellowish, compared to ssp. oregonum, which has straight white tepals (above the yellow zone at the base).  However, ssp. leucandrum is "supposed" to have white anthers, which, as you can see in the close-up photo, is not true in the case of these plants.  Actually, what I typically find is that a population of the Willamette Valley form typically exhibits a range of anther color on different plants in the population, some with yellow anthers and some with cream or almost white anthers.

Such populations, which don't exactly follow the published taxonomic treatments, can be confusing to gardeners, even those who are growing plants from wild collected seed.  So, I mention this in case anyone is growing plants like this that don't exactly fit the descriptions in the books. 

If you look in "Flora of North America" as well as other recent taxonomic references, you will not see ssp. leucandrum recognized as a distinct subspecies.  However, I think it is a useful taxon, both for field botanists and for gardeners.  For example, I was in Seattle last week, and a friend showed me some nice patches of Erythronium oregonum in a fairly wild section of the University of Washington Arboretum.  It was clear to me, however, that the plants were not wild populations, but had actually been planted some time in the past, because the flower and anther color of these plants matched the form we have in the Willamette Valley, not ssp. oregonum which is the only form that occurs naturally in the Seattle area (and even there it is rare in the wild).
Title: Re: Erythronium
Post by: Ian Y on April 06, 2007, 07:51:56 PM
Thanks for that great explanation Ed, it seems the plants are confused so not much wonder I am.
I like tha idea of having a RonCo automatic chromosome counter in the shed.

I have tried to identify them using the details in  Parks and Hardin but one year I am convinced I have
worked it out and the next year I work out a different name for the same plant.

I am just going to have to come over and see them in situ then I am sure it will all make sense.
Title: Re: Erythronium
Post by: Ed Alverson on April 06, 2007, 07:54:42 PM
Sorry, I intended to attach this third photo!

If you look closely in the photo, you will see two other associated species that closely guard our Erythronium patches - poison oak (which will give you a nasty rash if you touch it), and wild blackberry, which is introduced from Europe and tends to overtake these habitats unless they are mowed or burned.  So our Erythronium habitats do not give up their secrets too easily!

Our posts are passing mid Atlantic Ed.

Great to see more of them in the wild we have plenty out in the garden now and this is what I have as E. oregonum leucandrum.
 
Title: Re: Erythronium
Post by: Ed Alverson on April 06, 2007, 09:32:51 PM
Yes Ian, your plants look like "typical" E. oregonum ssp. leucandrum from southern Oregon (especially at low elevations in Jackson or Josephine counties, as ssp. oregonum can occur at high elevations down there).  The anthers are very white, but the dialated  (flattened) anther filaments show that it is E. oregonum and not some other white-anthered species like E. californicum.  The tepals show a creamish-tinge, though this doesn't always show up in photos, depending upon the exposure.  But, as they say, the plants don't always read the books, so if you find that some of your plants of ssp. leucandrum dare to have yellow anthers, it isn't necessarily an issue of hybridization or seed mix-up, just "normal" variation in wild populations.

Back to Aaron's great photos of southeast US Erythroniums, I also would really like to get to the southeast in the spring time. From what little time I have spent in the SE (not during Erythronium season however), the flora is really diverse and interesting, partly I presume because the area was not glaciated during the Pleistocene.

This series of posts has been an absolute pleasure to read and, of course, the photographs have been mouth watering. Many thanks, especially to those from North America who have posted photographs of erythronium growing in the wild. It is always a special pleasure and very informative to see plants in their natural habitat.

My own growing experience with erythroniums has not been extensive. I failed  miserably with seed on several occasions, germinating them with ease but failing to keep the young seedlings through the winter. I finally found a method which suited me. When the seedlings had reached a good size - in their first year - I planted them out, all in the one group as they were in the pot and they have thrived in the open garden. I suppose it is that they are left to their own devices and safe from  my interfering care.

Many thanks for the pleasure of reading and viewing your posts.

Post by: Ed Alverson on April 11, 2007, 05:57:36 PM
Susan, I enjoyed seeing your photos, especially the hybrids.  To id the one that has lost its label, take a look at the other side of the flower - if it has long stigma lobes, filiform (rather than flattened) anther filaments, and white anthers, it should be E. multiscapoideum.  E. californicum is similar but has short stubby stigma lobes.  E. helenae has yellow anthers and short stubby stigma lobes.  Also check Ian's recent article in the SRGC journal for photos of these species to compare with your plant.

Speaking of Erythronium hybrids, the Erythronium that is most available as bulbs from commercial sources is "Pagoda".  I have had it growing in my garden for a number of years and to be honest I don't quite know what to think of it.  It grows very well and forms numerous offsets (I've given many away) but the leaves are too big for the plant (so the flowers are not well displayed) and being a hybrid between a yellow flowers species and a white flowered species, the flower color is a sort of a muddy pale yellow.  But this year it looks better (maybe the weather has helped?), and when I took a photo of the flowers illuminated by the warm evening sun, it looks kinda nice.  So I guess I'll keep it!

Susan,

Please, have a look at this photograph as it shows the foliage.

Hello,
 
 I was very confused by the many collections I had at first. Then one year I was determined to figure them all out and see what was what. Now I know, but knowing the range also really helps. All my umbilicatum are from the coastal plain & peidmont of North Carolina, South Carolina, Alabama, and Georgia. I have avoided the E.u.var monostolon. I like the one bulb that does not run in the species.

 I grow very few americanum. I like the foilage, but the lack of flowers bothers me. I have seen areas where there were a decent number of flowering individuals, but....

 Rostratum is my favorite. Reproduces well, sets seed, and has large (3 inches/7.5cm) out and upward-ish facing fragrant flowers.

 I'll see what seed set I get after the 5 days of freezing weather and lows of 18F last week. So many things look like frozen lettuce now. Bulbs are an option for trade.

 The southeast is great. Early spring is awesome, but so is the summer. I have only seen a small piece of the northwest. I have seen the acres of E.grandiflorum at Glacier NP in Montana. My grandparents live only a half hour away from their. It is astonishing to see them by the millions even if the species is somewhat boring by comparison.

 I am in Kansas (in school and working at the herbarium), but have traveled extensively in the southeast exploring and botanizing, mostly botanizing, the past 7 years. Seems strange that of all the things I have seen, I discovered a new plant species (not Erythronium) almost in my own backyard!

Hi Aaron
Thanks for showing us the Erythronium pics, its good to get another perpective on them.
You are right, the names are a bit of a mess.
I would love to try E. rostratum, I don't think it is in general circulation here and it would be great to get the real thing from the start.
If you have a few spare seeds or bulbs I will trade, only problem is getting them into USA.

Great Erythronium pictures which together with the explainations have shown me several plants I am unfamiliar with.  Like Susan I would love to get some seed.  I am not sure that I have much to offer in return as apart from the Western Erythroniums I grow few bulbs.  Even my Erythroniums are not as good as those of the BD, Ian Y, although the Western species grow and seed well in my garden.  I do however grow other non bulbous genera if you let me know what particularly you might be interested in perhaps I can help.

A couple for comment.  I was given these by Gwen Baker (yes, the famous one) as she has to move out of her house.  I am pretty sure the first is White Beauty.  But is the second?  One plant in the second group has fantastically dark patterned leaves.

Diane from the picture there are three possible contenders for your second erythronium.
The white pollen suggests E. californicum, well marked leaves are typical of this species. E. 'White Beauty' is almost certainly a vigorous selection of californicum.
Without seeing the filaments I cannot rule out E. oregonum lecuandrum.
And the third possible id is a hybrid between the above two species.
A detailed picture looking into a flowers showing the shape of the filaments is required.

Susan, I have just read further back and seen your unknown erythronium which I think you correctly think is multiscapoideum.
If the scape brances low down into a number of long pedicels each with a single flower then it is multscapoideum.
There are a number of other very similar white erythroniums each with a yellow centre such citrinum, howellii, helenae.
My seeds that I recieved from Ron Ratko this year are now germinating, hurray - hurray.
More on this in the bulb log if I can get it written before I head off to Dublin on Wednesday, to talk on Thursday - BULB LOG LIVE - see you there.

Back to a few ordinary erythroniums, but then again they are only ordinary because they do well in the garden.

Thanks for this so far, Ian.  I'll try and get another picture of inside but they are going over fast with recent unseasonal heat.
My Ratko erythroniums are not yet showing any signs of germination although dicots from him are coming up well at the moment.

Brian and Susan,
 
 I am always interested in trading. I am currently looking for Chinese Polygonatum, or Muscari species. Forms of Muscari muscarimi and macrocarpum interest me greatly as do the small "grape hyacinth" types, the rarer ones. So many other things also interest me. Reply off-list for further discussing.

 For western Erythronium, henderonii is the one I want the most. I bought seed twice and have never had any luck. I want to make a spring trip to see them all some year, but next is out. Maybe the following?

 Best,

 Aaron

Aaron,

I can easily send you some fresh seed of E. hendersonii if you would like, garden grown and not wild, if that will work for you.  It will be ripe in about 8 weeks.

This was a unknown genus to me. Very nice flowers AND leaves!

In the 2007/08 issue of Lilies and Related Plants, which has just arrived,
there is an article by Brian Mathew on Erythronium.

He mentions the "Sulphur Form" of E. oregonum which has been grown
in the U.K. for many years.  When he visited Oregon, he saw it growing
in a garden there, and was told it came from Kelley Butte.

Now, there are two Oregon places with a similar name.  Kelley Butte
is a small park almost in downtown Portland, and Kelly Butte is in a volcanic
area almost in the middle of the state, in Deschutes National Forest.

Can one of our Oregon members tell me which is the most likely place
for me to go next spring to look for one?

Thanks for this information Diane, it sounds like I need to get a copy of Lilies and related Plants.
Erythronium oregonum sulphur form also appears regularly misnamed as E. citrinum.

Is this a publication of one or other of the societies please, it sounds ineresting?

Yes, it is the yearbook of the RHS Lily Group, which is celebrating its
75th year next year.  Membership costs 10 pounds.  Non-members
may also buy Lilies and Related Plants.  Details are on the website:
http://rhslilygroup.org/

The group has a good seed exchange which always includes many
wild-collected seeds.  Last year's list included 190 offerings of Lilium
species (and 10 of Erythronium).  The list comes out in January.
One must buy the seeds, and this helps keep the membership fee
low.

Diane,

The on-line place name index that I use lists 4 different places named "Kelly Butte" in Oregon, and another named "Kelly's Butte".  The one in Deschutes County is very unlikely because it is outside the known range of Erythronium oregonum.  The others, located near Portland, Eugene (two) and Roseburg are all within the range of E. oregonum.  If I had to guess, I would say that the Portland one is most likely, followed by Eugene, but this is just a guess.

Can anyone describe how the "sulphur form" is different from Erythronium oregonum ssp. leucandrum?

Ed

From the Cyclamen Society June 2007 journal:

The editor, Chris Clennett, has just finished a PhD.  The thesis
topic:  "A taxonomic revision of Erythronium L. (Liliaceae)

I wonder if it would be possible to see this?

Post by: Ian Y on January 05, 2008, 10:55:19 AM
Ed, I think that Etrythronium oregonum "sulphur form" is one and the same thing as Erythronium oregonum ssp. leucandrum which is the proper name for it.

Diane, I have also been aware of the Phd study and hope that it will get published so we can all read it.
