Erythronium 2010

[Luc Gilgemyn]

In that case the mistery seems to remain unsolved Maggi... 

[gote]

Well, It seems certain, however, that it is not a case of flowering and non-flowering clones.

From my own experience - from other plants - disregarding Gerben and Henrik - I would have believed it to be more a question of light.
Would there be any difference there Maggie?

I have noted that some woodland species - and some Nymphaeas - switch between a (juvenile?) non-flowering stage and a floriferous stage.
A setback will take them back to non-flowering. They seem to start flowering if remining in the same spot and growing sufficiently well there.
Lilium lankongense behaves just like  E americanum. It proliferates (and migrates) by stolons without flowering but if one of the many offsets finds the situation good enough, it will turn into a flowering bulb. Fritillaria camtschatkensis behaves in a similar way.
More nutrition seems a likely way to push the plant into flowering but I assume more light or a better watering regime could work in the same way depending upon what the bottleneck might be.

Cheers
Göte.

our non-flowering patch turned into a flowering one... and we had not lifted or dug at all, and certainly no manure! 

I've had the same thing happen Maggi --An established non performing patch suddenly flowering.

However a friend of mine feeds her trilliums with pelleted sheep manure --they are vigorous plants with strong flowering stems .......

My modest collection of possible erythronium hybrid seedlings have begun to flower.
This pink is recorded as "Californicum white beauty x Helenae", but that appears extremely suspect.Some pollen of Revolutum pink beauty I guess is the likely donor?

Very nice Paul

Here are

Erythronium dens canis
 
Erythronium dens canis snow flake

Erythronium grandiflorum ssp pallidum - lifted from a trough about 8 weeks ago and planted into fresh mix in a pot.At the time of lifting i could only locate 2 bulbs which confirmed my thoughts that the clump wasn't doing particularly well. However today i found a number of seedlings in growth left behind in the trough .....

So far, my patch, about 80cms across last year, of Ery. umbilicatum has totally failed to show. I'll have a look later this morning and a dig around but if it has all died I'll be devastated. Why ever WOULD it?

[Gerry Webster]

On a visit to my local garden centre today I found packets of E. dens-canis among the dry bulbs.  Completely dead corms were available  for £2.99 each. Quite a bargain!

[Guff]

Planted these the other day, two bulbs in each baggie. Have another 10 mixed non-named Dens Canis still to come in the mail. Hopefully(crossing my fingers) I see some flowers come spring.

[Lesley Cox]

My patch of Ery umbilicatum is up at last and has a couple of buds today. Why so late compared with Dave's?

In flower now is Ery 'Ruapuna Dawn' a wonderful vigorous hybrid from Joan Whillans, probably revolutum x californicum 'White Beauty. Seedlings from RD come same as WB.

The two for ID please. I thought they were the same but one has white anthers while the other has yellow.

[Maggi Young]

Joan's Ruapuna Dawn is a gem, isn't it?

The first yellow looks to be a E. helenae.... if the style does bend downwards, as it appears to. The filaments seem straigth sided and the anthers pale... so helenae or a hybrid of it. It might just be  multiscapoideum...... you'd need to have a poke down through the grass!
The second has a style which goes out at right angles from the center, it seems.... the  anther filaments have the broadened "dutchman's breeches" shape.... so an oregonum......

[Lesley Cox]

Thanks Maggi, After another close look I'm still puzzling. All I'm sure of it that it isn't multiscapoideum. Single stems from single leaves. There's a fresher flower out this morning on the first and the yellow markings are slightly different, so probably a hybrid batch. They were grown from seed ages ago.

Hi Lesley

I believe your erythronium pic - the one with the white pollen is of E. multiscapoideum. Not all branch early or may never have multiple stems. It has white pollen and a moderately branching stigma and a nice bright lemon to yellow centre blotch. And it usually is mid-sized and outward-facing.
 
Its not E. helenae which is almost identical but ALWAYS HAS yellow pollen.
 
It is not E. oregonum. It is bigger, the flower is held downwards and the pollen is yellow except in leucandrum. The flower colour is a bone white to greenish white. It doesn't have a big bold central blotch.
 
It is not E. howelli. It has yellow pollen and a clubbed stigma but it does have the big blotch, often more orange, and is outward facing.
 
 
I hope that helps.
 
Cheers, Marcus

Lesley,

I love the 'Ruapuna Dawn'!  Great leaf colour and excellent flower form.  I'm glad the umbilicatum has surfaced.... pics please when available?

Howdy Marcus!!

[Hillview croconut]

Hi Paul! 

have your trout lilies finished up there on the big island?

Cheers, Marcus

[Paul T]

Marcus,

Not quite.  I still have a couple of flowers on multiscapoideum, and some 'White Beauty' seedlings from a friend a few years ago.... and one other that I can't recall the name of right now.  The oregonum ssp leucandrum pot has just finished in the last few days.  Some great germination on seed of japonicum, sibiricum and caucasicum recently too, so I hope they do well in the future.

So do you have the 'Ruapuna Dawn' imported as yet? Just asking!
