This year my first Erythronium to flower has been E. tuolumnense. Starting a week ago I've been taking a photo of the same clump every day to see the progression in flower emergence. Not sure how effective this sequence is, but you can definitely see how the plants respond to the daily weather conditions. Here are the first five days.

And here are the last two days.

Interesting series of pictures, thank you. :)
-
Your series show how quickly the flowers are visible, even as the foliage and stems are still developing- wonderful plants!

Erythronium revolutum, thickly sown in the open ground:
[attach = 1]
Erythronium californicum, April 2011:
[attach = 2]
Note the use of the inverted flat to deter birds, rabbits and mice.
-
Nice to see E. tuolumnense growing well. What about the temperatures
when taking the pictures? A dream of green and white colour!!!!!!!!!!!!
Thanks for the pics, Ed.
Uli

Ed, of course a dream of green and yellow!!!!
Uli

Uli, I was taking the photos during a warm spell, which did speed things up a bit - high temps 55 to 65 degrees F, (13 to 18 deg. C). Now the weather has turned toward a cold rainy spell, so even though spring is here, it feels a bit like winter. But I don't mind - the cool temperatures actually prolongs the length of the flowering period, so I get to enjoy the flowers for many weeks.
Gene, I had good establishment of self-sown seedlings of E. revolutum last year (seeds produced in 2011), which makes me think that these things are episodic, every few years the conditions are just right for good production of viable seed and subsequent establishment and growth. Given the 5 year time investment from seed to flowering specimen, you have to be in it for the long haul anyway, so I don't really mind if increase/establishment is episodic.
Ed

If you have Erythroniums in the garden, watch out for voles and mice. They will eat every bulb over the Winter, and you won't know until Spring. You can bait or trap the critters, or you can surround your bulb bed with buried hardware cloth.

The first of the season for me -- Erythronium american. E. revolutum is not far behind.
-
very beautiful americanum, Claire!! love it!
Anybody tell me, why my E. americanum never flower, only making mass of leaves and stolons..... we're together in such vegetative manner during 6 years .... :-X :-X

We have some E. americanum which are reluctant to flower and some which are happy to flower every year. But we had, for many, many years, patches of only leaves .....then one year ( and Ian has described all of this in the Bulb Log) flowers began to appear. Now these patches flower well every year.

More sun, more flowers. I see this pattern in many woodland plants.

I ordered another batch of seeds from Alplains, December 2012. I had enough screened compost to start Elegans, Hendersonni, Oregonum ssp. Leucandrum and Revolutum seeds in pots. Stuck the pots in my basement, Hendersonni and Oregonum ssp. Leucandrum are starting to germinate. No germination yet with Elegans and Revolutum seeds.
-
Erythronium elegans and revolutum along with grandiflorum seem to germinate later with me than the others. Hendersonii is the first to germinate here with germination in December from autumn sowing where as elegans is only just starting. There is hope yet.
I am please to see you are germinating them now from a December sowing as I got a batch of seed in December and sowed them in the hope that I wasn't too late.
Susan
-
I also ordered seeds of 6 Erythronium species from Alplains, and planted them as soon as they arrived in early December 2012. Only one species has just started to germinate - Erythronium tuolumnense - which is also an early flowering species that comes from relatively mild climate. Early December is 2 months past the optimal planting time so it is logical that germination might be somewhat delayed, but I do agree that it is better to plant at that late date than it would be to wait until the next fall.
-
I sowed a batch of seed I collected from my own plant of Eryththronium revolutum 'Knightshayes Pink' last June/July and sowed them immediately. To date no germination at all.
-
E. sibiricum sown here last December germinated well, but may be one of the easier species.
There's an interesting article on its traditional uses here (http://www.sgr.fi/susa/93/stahlbergsvanberg1.pdf).
-
Sunny and warm here today, a high temp of 72 deg. F (22 deg C.), the warmest day so far this year. Most Erythroniums are at their peak of bloom and the warm temps put them in prime condition. The only downside is that the warm temps will also shorten the bloom season.
Erythronium oregonum ssp. oregonum
Erythronium oregonum, closer to ssp. leucandrum
Erythronium helenae (interesting how the tepals on these flowers are not reflexed, even with the warm sunny conditions)
Erythronium tuolumnense, a small flowered form that resembles E. pluriflorum (or may just be a fluke of this year's growing conditions)

A few more from today:
Erythronium revolutum
Erythronium hendersonii
E. hendersonii x revolutum

Lovely set of pictures Ed, many thanks.

Gorgeous pictures Ed ! :o :o
We can only dream of 22°C out here at the moment... :-\

Sometimes at this time of year we'll get a warm zephyr blowing in from California - that is the advantage of being at 44 degrees latitude. Tomorrow it may be cold and rainy again.

Guff, what was the temperature in your basement over the winter? E. revolutum grows on the Oregon coast, which does not get a lot of chilling. I'm curious about the actual chilling requirements for these seeds.
David, did you keep the mix moist all last summer? If so, they may have rotted in high temperatures last summer. It's best to sow the Pacific coast natives in early fall as the temperature is dropping. What was the highest temperature the sown seeds were exposed to? In nature, the seed is dispersed in midsummer, but the soil is fairly dry until late fall. Usually, the seeds get covered by organic matter, or carried underground by ants, so the seeds stay cool.
If you receive seed in January or later, I recommend placing it in a sealed container and storing it in the freezer until next fall. There will be no loss of viability. In fact, you can freeze it for ten years, and there will STILL be no loss of viability. But if you plant it late, and it doesn't germinate in the next spring, you may lose all of them.

My Erythronium revolutum bed in full bloom, with gazillions of seedlings growing like mad:
[attach = 1]
A closeup:
[attach = 3]
Ed lives about 100 miles south of me, in the Willamette Valley "banana belt". So his plants will be "first out of the gate" every time. The US west coast is an amazing place for plants, because the climate can be so different from place to place, especially if you travel over a mountain range. My place is 50 miles north of Portland, Oregon, but I can grow things here that I could not grow in Portland, because it was too hot there. Some of the species lilies were impossible there. If you can't grow a particular plant, it may not be that you lack skill. It may be that the plant does not like your climate or soil. For example, a climate with heavy rain and high temperatures late in summer will not work well for plants from the Pacific Northwest USA, like Erythroniums. Special measures will be necessary.
-
Coldest part of winter, basement temps are 36-40 range.

Thank you for this advise. :)
Last year I sowed several species of Erythronium seeds from the seed exchange. I kept them first 6 weeks in warm and then 3 months in cold (near zero celsius), no germination in spring, so then they were outside the summer and winter again close to zero temperature in the cellar, and germinated now in March, but only about 2-3 seeds out of 10 germinated in each pot. I was hoping the rest would germinate later, but perhaps not. Still, I'm happy that some germinated anyway, and I have a start of a collection now. :)

Gene, in the UK last year we had one of the worst Summers on record with incessent rain and low temperatures. I think it's likely there were not many days when the temperature exceeded 22/23C.
-
Garden still covered by deep snow. Even in greenhouse only earliest erythroniums are flowering:
Erythronium caucasicum from Georgia in Caucasus
and
surprisingly early cultivar of Erythronium sibiricum selected by Arnis Seisums (?) and named EARLY WONDER because it allways bloom the first and together with earliest erythroniums. Usual forms of sibiricum is much later blooming and some even very late.
-
Coldest part of winter, basement temps are 36-40 range.
That's the normal temp range for cold stratification. I don't have the evidence, but I'll bet the Pacific coast Erythroniums like revolutum and hendersonii will germinate with warmer winter temps like maybe 50-55F. The Oregon coast doesn't get much colder than that on average.
-
Happy to see that my Purpurascens, Hendersonii and Oregonum plants are above ground. The Oregonum looks like it will clump up fast, had two flowering scapes last spring. Last year Purpurascens and Hendersonii started to flower March 23.

This Revolutum flowered last year, must have forgotten to post it in the 2012 Erythronium thread. Has six stamens and alot darker pink.

A group of mixed species and hybrids:
[attach = 1]
After you've grown Erythroniums from seed for a while, you will need a place like this for mystery plants.
Some of them have very dark mottling on the leaves:
[attach = 2]
Does anyone know if this is a named hybrid? I looked up White Beauty, and it does not have mottling this dark.
-
Hi Gene
Here's a picture of wild E. californicum taken last year in Trinity County CA. Only one leaf is visible and out of focus but they were very mottled.
I went back and collected seeds and sent some to the SRGC exchange. Did you order any?
Larry Neel
-
Larry, I have several groups of E. californicum with mottled leaves, but this particular plant has much darker mottling and much bigger leaves. Someone once told me that they thought it was a form of californicum, but I wouldn't be surprised if it's a hybrid. It's a very strong grower, and makes bulb offsets.
-
Some erythroniums from my collection grown in greenhouse
Erythronium grandiflorum - American
Erythronium caucasicum from Georgia
Erythronium dens-canis from Lipcha in Eastern Carpathians
and a pair of Erythronium sibiricum
from Marble pass in E Kazahstan (12KZ-098)
and subsp. sulevii with black anthers
-
Gene, for some reason your pictures don't go to full size when clicked? One has to save the file then open them.
-
Anyone ever find out if Japonicum and Dens Canis cross? Think I'm going to have around 13 Dens Canis and 3 Japonicum flowers this year.

They work OK for me. Maybe Maggi can tell me if I've done something wrong when I attached them.

Tried them on the machines we have here, on different browsers too..... seems to be okay so not sure what is happening for Guff.
Once in a while I have experienced a temporary problem of the photos "wanting" to be opened in a new window or be saved or just not opening at all for five minutes. . I find these are all temporary blips.
Sometimes there is just not a good answer to these glitsches
-
Can anyone ID these for me? I found them about 50 miles east of Arcata, CA near Burnt Ranch. Note the strong pink coloration.

The foliage looks like E. californicum.

[Regarding Gene's pics:] Sometimes there is just not a good answer to these glitsches
That must be it. Before, left clicking did nothing for me either (FF 20), but I could right click for an option to enlarge.
Now, everything is fine, and normal left clicking works.

Thanks, Rick - the internet is a wonderful tool, but it is sadly not without it's idiosyncrasies :-X
-
Think it has to do with text between and after the pictures. There are 4 options when uploading the picture maybe this is causing the issue for me?
I tried the newest version of Opera browser and when you left clicked the picture it opens in a new window. Then you need to hit the back button to return to the forum.
I will try crossing two Dens Canis flowers with pollen from Japonicum. Would be nice having a bigger flower of Japonicum that clumps up like Dens Canis.
-
The pink tinge to that flower is very nice.

Gene Mirro, magnificent find!
It is a little Erythronium caucasicum from this year.

Gene, was this just one plant mixed in with a larger number of normal E. californicum, or was the entire population showing the pinkish coloration? Would it be correct to say that the site is farther inland than E. revolutum typically grows, and south of the limit of E. hendersonii?
Ed
-
Ed, they all have the pink coloration. According to the Pacific Bulb Society website, hendersonii is only found in the Siskiyou mountains. Revolutum can be found in the coast ranges all the way down to central California. I found these plants along Route 299, about 30 miles straight east of Arcata (50 driving miles). Is that still considered the coast range? I don't know.
I can't find a description of a California Erythronium species with this coloration. So I suspect they are hybrids with revolutum. But I am not a botanist. The foliage looks exactly like californicum, and they are blooming at exactly the same time as californicum in my garden. I grew the plants from seed collected at the Route 299 site. So there is no chance of garden hybridization.
This is what revolutum looks like down in the bay area:
[attach = 1]
[attach = 2]
The coloring is much weaker than the more northerly forms. These are growing in my garden from seed purchased from Tilden Botanic Garden. They say my plants are identical to the form which grows naturally in that area. Note that the foliage on my "mystery plant" doesn't look like this at all. It is narrow and darkly mottled, just like californicum.
-
Gene we have lots of plants just like that self seeding around our garden - they are hybrids between californicum and revolutum, some other species, E. oregonum, could also be involved.
The shape of the filaments in your pictures suggests that revolutum is involved - you maybe have long distance bees doing some pollinating.
Many of these hybrids in our garden are fertile and the seedlings are very similar to the seed parent so it could be that cross pollination happened at some time in the population you show and then it has increased by seeding around.
-
We have usual summer weather pouring rain again, super Erythroniums, I am posting two pictures of Erythroniums which I have had for about 8 years suggest E. hendersonii hyb Ardovie Bliss and E. sibiricum seedling E. sibiricum Amur star (Amur is a type of Siberian Tiger) cheers Ian the Christie kind.

E. sibiricum Amur star is nice, can you take another when it opens to see the markings?
Not sure about the Snowflake, book I have says blue anthers.

Erythronium californicum x multiscapoideum
Seed from SRGC seed ex sown in January 2010 and germinated in April.
I found this bulb in the tray under the pots. This was the nearest Erythronium pot apart from japonicum which it is not.
No sign of flowers in the original pot.

Just fantastic those really dark Erythroniums are superb thanks for posting, cheers Ian the Christie kind.
-
Wonderful Dimitri. I've never seen such dark flowers.
-
I agree with Ian and Gerry . Fantastic colours Dimitri , unusual too ......Did never see something like that .Thanks for sharing !
-
Fantastic to see my favourite flowers in their habitat - I love the pink coloured forms of Erythronium caucasicum and have never seen anything like that before.
The dark dens canis are also spectacular.
Are you planing a return trip at seed time?
How close are the locations of E. caucasicum and E. dens canis, could there be cross pollination?
Thank you Dimitri and Natalia for sharing your beautiful pictures.
-
phantastic flowers from all,
here some yesterday in my garden:
Ery. dens-canis 'Charmer'
'Lilac Wonder'
'Moerheimii'
'Pink Perfection'
'Snowflake'
-
and two pure species:
Erythronium caucasicum and
'' umbilicatum, the first yellow ( i think )

Ian! Thanks for your post! From now still wait for seeds in my garden)) The both species are separated as by geographically but also by reproductive isolation mechanisms, as I suppose. BUT! it would be very interesting to obtain the interspecific hybrids - so, Ian - go on!! ;D

1-2 Japonicum
3-5 Hendersonii

A lot of Erythroniums are blooming in greenhouse, but outside only noses are shown on beds. Very interesting is E. oregonum 'Covichan Star' selected by Art Guppy - its flowers looks up. On next picture E. oregonum leucandrum. One of most beautiful is E. hendersonii. Erythronium umbilicatum has yellow flowers. As last - Erythronium howelii. More you can see on my home page - chapter Garden News.

Fabulous Erythroniums everyone.
Does anyone know why my E. dens-canis do not flower. They are in bought soil improved with leaf mould and grit. In the same bed are Snow Goose and Kinfauns Pink which are prolific. The bed was made in 2009 and in this time flowers have been absent

Mark - it took me several years to find a position in the garden - under a N. wall - where E. dens canis would survive & flower though the Americans have always done well no matter where. My limited experience suggests E. dens canis is a fussy plant.
-
Mine get full sun at this time of year until approx. 9am or maybe 10
-
More sun = more flowers.
-
More sun = more flowers.
But Snowgoose and Kinfauns do so well in the same bed
-
More sun = more flowers.
I think that might depend on where you live.

Some from the garden yesterday.
Erythronium 'Pagoda'
E. 'White Beauty'
E. revolutum 'Knightshayes Pink'
all of these in a North Eastern facing bed in gritty soil top dressed with composted bark annually. Pagoda has been in-situ for about five years starting with three (bulbs?); White Beauty for about three years starting with with one and Knightshayes Pink bought from Beeches Nursery earlier this year to replace another Knightshayes Pink which flowered last year, gave me loads of seed and promptly disappeared. May have been my fault since I did a bit of re-construction on the bed and may have dug it by mistake.
I have two dens-canis in a peaty, East facing bed under a Camellia, bought from Susan Band in 2011 one of which I'm sure is in bud and the other possibly may be. That bed also has E. tuolumnense and E. 'Kinfauns Pink, again from Susan which are a little behind dens-canis.
-
Mark, there can be some clones of E. dens-canis which are a problem to flower. Is it all one clone or are they different plants from different sources?
Susan

Susan I cant remember where they came from ::)
Some of the leaves

I ordered another batch of seeds from Alplains, December 2012. I had enough screened compost to start Elegans, Hendersonni, Oregonum ssp. Leucandrum and Revolutum seeds in pots. Stuck the pots in my basement, Hendersonni and Oregonum ssp. Leucandrum are starting to germinate. No germination yet with Elegans and Revolutum seeds.
Five of the six Erythronium seed lots I ordered from Alplains and planted in early December 2012 have now germinated nicely - this includes E. idahoense, which I am expecting to be a bit difficult because its native climate is continental rather than maritime. The only species that has not germinated is E. klamathense, but being a high elevation species I didn't have high expectations anyway.

Last week I went for a hike along the Rogue River trail in Josephine County, SW Oregon. It is about a 2 1/2 hour drive to the trailhead so it makes for a long day trip, but it is definitely worth it. All sorts of interesting plants can be found here, I was actually mainly looking at the ferns.
Erythronium oregonum is common along the trail on the south (shady) side of the river, though past the peak bloom I still found a few good flowers. There were lots of leaves so I definitely need to visit next year a bit earlier in April. The trail is along a particularly scenic part of the Rogue River, and in many places the trail has been blasted into the side of vertical cliffs. It had rained a few days earlier, and in one spot there was a set of waterfalls along a small side stream dropping in to the canyon (this is in the 4th photo).
This region probably has the greatest Erythronium diversity in the world for a similar sized area - go 15 miles south from here and you are in Erythronium hendersonii country, then another 10 miles south to Erythronium citrinum land, and 10 more miles or so south it is Erythronium howellii. Erythronium grandiflorum and E. klamathense are at higher elevations so they bloom later. Add in both subspecies of E. oregonum and E. revolutum which grows on the western side of the county, and Josephine County alone has 8 native Erythronium taxa.

Rob, I believe all E. grandiflorums are yellow. One source says that parviflorum has white or light yellow anthers. Take a look here: http://www.srgc.org.uk/bulblog/log2008/300408/log.html (http://www.srgc.org.uk/bulblog/log2008/300408/log.html) at the photo of Erythronium revolutum hybrids. That looks a lot like yours. I don't believe pure E. revolutum has the dark band near the base of the petals, like yours does.
Also, take a look at my reply #44 in this thread. That's probably a hybrid between californicum and revolutum. Just guessing here.
Another clue with E. grandiflorum is that it can be very picky about where it will grow. Even in the Pacific NW, it is common to have 100% losses with them, planted right next to many other species that are doing well. I believe it's because it comes from a dry summer climate with cold winters. Maybe Ed can help with this.
-
Rob - I agree with Gene that your plant is probably a hybrid - E. revolutum x californicum. I have one that is virtually identical.
-
Whatever it is Rob it looks great

Gene is correct, Erythronium grandiflorum var. parviflorum is the name for the white anthered form of E. grandiflorum, and is the predominant type in the Cascades and Coast Ranges of northern California, Oregon, Washington, and British Columbia. The red anthered var. grandiflorum comes from the inland regions of the Pacific Northwest, and var. chrysandrum, with yellow anthers, is mostly in the Rocky Mts. along the continental divide. However, most recent floras don't recognize these varieties.
I've been able to keep E. grandiflorum var. parviflorum alive for about 8 years. However, the source population is a low elevation woodland in the eastern end of the Columbia River Gorge, so these plants spend little time under snow in the winter. It helps that these plants are growing under the eaves on the west side of my house so they get somewhat less rain on them in the winter, and in some years when we have had a rainy spring I've covered them with a plastic hoop frame to keep the bulbs dry after they have gone dormant.
Art Guppy has reported success with this plant in his garden on Vancouver Island using seed collected from a mountain in the Oregon Coast Range about an hour's drive from my house. This site is less than 25 miles from the Pacific Ocean and at about 2400 ft. does not have a consistent winter snow pack. I'll have to try to get up there soon to take a look.

I've just come across an old article claiming there is carbon transfer between E. americanum and sugar maple through arbuscular mycorrhizal fungi: http://www.jstor.org/stable/4223326 (http://www.jstor.org/stable/4223326)
It is a wild guess, but I wonder if this may explain why it rarely flowers. Mine never flowered. Perhaps it has to grow under specific trees. In your experience, could this be the case?
-
Some of you may have heard of a huge wildfire in California, called the "Rim Fire", which has burned over 150,000 acres so far, including portions of Yosemite National Park. What the news media haven't told you is that this fire has burned the entire natural range of Erythronium taylori. Hopefully the fire wasn't too hot when it burned through the Erythronium habitat (and these plants are at least somewhat fire adapted), but any species with such a small natural range is inherently vulnerable.
There is a blog at http://wildfiretoday.com/2013/08/21/california-rim-fire-west-of-yosemite-np/ (http://wildfiretoday.com/2013/08/21/california-rim-fire-west-of-yosemite-np/) that posts daily updates on the fire. If you scroll down to the aerial map of the fire perimeter, you'll see that the fire has burned on both sides of Hwy 120, but mostly on the north side. The area within the fire perimeter that is on the south side of Hwy 120 is where E. taylori grows.

Yes, Ed, we are seeing the frightening progress of this huge fire on the TV new reports.
As you ay, we can only hope that the fires passing over the Erythronium have not been so hot as to penetrate to the bulbs.
The scale of the damage being done - and the seemingly endless expansion of the fire area - is hard to comprehend.

I've just come across an old article claiming there is carbon transfer between E. americanum and sugar maple through arbuscular mycorrhizal fungi: http://www.jstor.org/stable/4223326 (http://www.jstor.org/stable/4223326)
It is a wild guess, but I wonder if this may explain why it rarely flowers. Mine never flowered. Perhaps it has to grow under specific trees. In your experience, could this be the case?
There were carpets of them in flower in mixed broadleaf woodland in Ontario in early May. Some maple in the mix for sure, but other species as well. See my post on "Springtime in Southern Ontario"

Update on seeds I was germinating in basement. I did have a few of the Revolutum seeds germinate, none for Elegans. Plastic pots bottoms were cut out so I could put them into a new bed, without disturbing them too much.
Seeds that I had collected this year. Made another bed for these seeds, hopefully a lot germinate. Anyone have any extra seeds in USA for postage?
