Title: Erythronium 2019
Post by: David Nicholson on March 05, 2019, 01:02:14 PM
The first of my season Erythronium dens-canis 'Snowflake'. I did wonder if I might wait for the flower to open but since we shall be away for a week it's likely to be over by the time we get back.

Looks to me as if that flower is a little "stuck" at the tip - give  it a little tweak and it should pop open to let you enjoy it before you leave  :)  (  Unless the  ghastly weather  we've just seen on the forecast for your area has already arrived!!)  :-X

Erythronium dens-canis ssp. niveum
[attach=1]

Erythronium grandiflorum ssp. grandiflorum was the name on the seed-packet but Erythronium grandiflorum var. pallidum is better I think.

Hello fellow erythronium fans. Being in the Southern Hemisphere i will sit back and enjoy your posts . Please keep them coming. Late last year I bought some styrofoam boxes containing erythronium from Paul Rumkorf, a contributing members some time back.  I was delighted the bulbs were in good condition and in good numbers , as I bought them on a dormant and on trust. Nothing like assuring your other half, yes there is something in this potting mix, 😂.
I also planted a bagful of revolutum bulbs from Jane Tonkin, that we’re a generous gift for a recent big birthday. Thx Jane.
Hopefully I will get some heavily marked leaves and hours of pleasure in October.

My friends from the Midwest tell me they remember Erythronium albidum and E. americanum carpeting the forest in the spring.  What I've learned is that both are very slow at colonizing for me but patience can be rewarded.   :)

This is the third year I have grown this plant and I've never been sure if it is Erythronium oregonum as I bought it or if it is actually E. californicum. A study of Ian Young's book shows clearly that pollen colour in oregonum is white (mine is yellow) and the flower on my plant does look very much like californicum. Ian help please!

I have 2 groups of Erythronium tuolumnense in my garden. ~50 or so round a tree, originally planted 2 years ago as small offsets, but now flowering size, and another smaller group under another tree, just large enough to produce some flowers. The latter group has lost all its flowers and nearly half of the first group. Just stalks left. Very neatly disbudded.
Can't make up my mind which creature is responsible. Deer or Pheasants most likely. I fenced off the first group so we can see something this year. Is something attracted to yellow/green buds? Not noticed the deer being choosy about the tulips they eat.

This erythronium is a hybrid from a friends garden in Monefeith.  There is probably a bit of E Hendersonii in its parents.  She named it 'Ardovie Bliss'.  It has proved to be a bit difficult to please.  This clump has sadly gone.

David I think you need to take another look at my book - most forms of E.  oregonum have yellow pollen but there are some with creamy white pollen, they are often referred to as 'sulphur' form E. Californicum has white pollen however from what I can tell f om your pictures the shape of the filaments in the one you show looks to be a pale pollen form of E. oregonum.

E. "Ardovie Bliss" is indeed a very beautiful hybrid of E. hendersonii and as you point out it has proved challenging in some conditions we still have a slowly increasing group built up from a single bulb that I planted into a new bed last year, they are in bud just now.

The pictures following were taken yesterday which was one of those days of intermittent heavy rain showers followed by sunny spells, followed by heavy hail showers, followed by another sunny spell. The kind of day spent putting gardening tackle back into the garage and dashing back inside again so four pictures took most of the day! It was also a day,  where yet again, I tried to come to terms with the manual settings on my camera. I've done this many times before but each time I fail to remember the lessons I've tried to teach myself, maybe it's an age thing?

First picture is Erythronium 'Craigton Cream'. One of the many other things I'm trying to learn is to be less bothered by plantings which scramble together. Really I'm trying to begin to emulate Ian Young's approach that he wonderfully shows in his garden on the Bulb Log and Videos of sweeping plantings and colour inter-mixed. So 'Craigton Cream' is here together with a very nice white Primula vulgaris and Muscari macrocarpum.

Erythronium californicum. Had it been a reasonable day I would probably have tried too to get a shot of the inner flower--maybe next time!

Erythronium 'Craigton Cover Girl', one of the few Erythroniums I have yet that clump up well and in an area where I hope to eventually spread more Corydalis seedlings.

Erythronium 'Joanna' a John Amand introduction originally, a tuolumnense / revolutum cross. If we get a dry day I shall try to get a picture of this inner flower too.

My brother has a plant he bought several years ago as E. helenae finally in flower.

I asked him to check for a bent style, but he says it has stamens, but no style, and no ovary.
All of the three flowers on the stem are the same.

How odd!  Has anyone else ever observed this in any erythronium?

I have soon occasional plants where for some reason the style does not form, usually this is due to immaturity or some damage, but I have not seen any without some form of an ovary.
Any chance of seeing some pictures?

Lovely, Herman - but 'Citronella' is not  a revolutum form -  Erythronium ‘Citronella’ is an old hybrid of Erythronium tuolumnense and probably Erythronium ‘White Beauty’.

Leena, we have some that look exactly like this the petals have been eaten by something a slug, snail or possibly some kind of insects grub that lives underground and only comes out at night.
I know this because one of our white sibiricum had two flower stems one looked like yours while the other yet to open still had petals next day they were gone also.

Cutworms, which are the larvae of large moths, are active in the spring.  They hide just under the soil surface during the day, and feed at night.

Some cut at ground level, but we also have a climbing cutworm, the caterpillar of the large yellow underwing moth. It becomes an orange or dark red pupa during early summer.

It is common in Europe.

Thank you Ian and Diane.

Leena, your sibiricum has flowered underground! It happens more, they seems to need a quick change from cold to warm to get the flowers higher.

This has been a strange spring, and especially nights have been very cold, days from 0-10C, and only a few days which you can call warm. I don't remember how it was last spring when these flowered normally.
It is also possible, that there are something eating the petals, but they must have eaten them in the ground because when this plant came up, the flower bud looked strange to begin with, and now when I think it didn't have petals even then like the other bulb does. There are different kinds of moths here, so it is quite possible that their larvae are somewhere in the ground and eat up whatever they come across  :(.

Our oregonum are in full flower now, in the woods and along roadsides.

When I was young, we would never have seen any along the roads as they would have all been picked.  It was a spring ritual to go picking big bunches of what we called "Easter Lilies".  We were taught never to pick the leaves as that would prevent the plant from flowering next year.  No thought that we were preventing the formation of seeds, though.  Some people had bunches that needed both hands to hold.

My family picked only modest bunches.  We were interested in finding the plant with the most flowers on a stem.  I think our record was eight.

I don't know when it became unacceptable to pick wildflowers, or what triggered the change.

Art Guppy, who lived near me on Vancouver Island, Canada, died last year.

He wrote interesting articles about Erythroniums, and I think was the first to separate the species according to how their seeds were dispersed - by ants, or by movement of the capsule.

His articles have been collected here:  https://artguppy.wordpress.com/

A nice patch of an erythronium labelled as E. dens-canis recently seen in the BG Munich, maybe two weeks ago.. I believe it might rather be E. albidum. Any thoughts?
Title: Re: Erythronium 2019
Post by: Maggi Young on May 11, 2019, 06:46:39 PM
Looks as  E. albidum - probably the  plants  "ran" into the  area where the  dens-canis  label was.   A  danger  with  "travelling"  plants!
Title: Re: Erythronium 2019
Post by: Tomte on May 11, 2019, 07:29:55 PM
I rather think it was the other way around and the label ran into the area where the E. albidum are growing  ;).
They cover at least half a m2 and grow there as long as I can remember, something I can't say about the label. It's also rather shadowy in that spot. Most dens-canis in the rockery seem to prefer a more sunny aspect.
