Erythronium 2016

[fleurbleue]

I bought some E. dens canis few years ago and they have never flowered   

[Maggi Young]

Oh dear - I hadn't realised that was a problem with dens-canis. 

[Jon Evans]

I have always found E. dens-canis difficult to flower in pots.  Nowadays I put them out in the garden, where you don't notice them until suddenly one bulb or a pot of seedlings has bulked up to form a clump which flower well.  Usually that seems to be a sign to dig them up and split them up - if I don't they often then dwindle and disappear; of course if I do I'm back to waiting again.  But then gardens in Southern England are probably not an ideal habitat for it.

My first of the season (even White Beauty isn't out yet) Erythronium 'Knightshayes Pink'

[Chris Johnson]

Erythronium tuolumnense 'Sundisc'

[Roma]

I planted out some Erythronium revolutum last year.  I wonder if the flowers will ever open properly.  This cold damp weather is forecast to continue for the rest of this week.

We visited Knighshayes today and the Erythronium revolutum were absolutely stunning. Will try to post some pics in the 'Places to Visit' thread later today or tomorrow.

I was surprised to read a comment the other day that all  the  commercially available Erythronium dens-canis cultivars are shy flowering. Have others found this to be the case?

I don't know about all Maggi, but quite a few seem to be. Just as well the leaves are attractive. My general experience is quite similar to Hepatica in the garden actually (for which see another thread) - they increase slowly, flower sparingly and some clones will fizzle out entirely. Perhaps seed raised is the answer.

I planted out some Erythronium revolutum last year.  I wonder if the flowers will ever open properly.

My observation is that the degree to which the tepals of Erythronium flowers open is at least in part a function of temperature and relative humidity. There is a nice accessible population of Erythronium revolutum in the coastal mountains not too far from here. The site is basically in temperate rain forest; annual precipitation is 80 to 100 inches. Since dry days are uncommon in early spring, usually when I visit the E. revolutum flowers are quite droopy. I've attached 2 photos from this site, the first taken on a rainy day in 2014, and the second taken this year on a dry day, when there had been no rain for nearly a week. So at least some of the time the flowers at this site open nicely!

This feature probably varies with different species as well, and perhaps for different populations within a species.

Looks like a good form too Roma, nice leaf markings. Is this the first time they've flowered?

Erythronium tuolumnense


Erythronium oregonum


Erythronium hendersonii

[ArnoldT]

I planted one Erythronium about ten years ago in this spot.  It has spread ever since but not one flower.

Ideas?

Thanks,

[Claire Cockcroft]

It might be E. americanum, which spreads in my garden in the same fashion and is shy-flowering.

Claire:

Thanks, I'll have a look at them.

My brother hiked up Mt Prevost, in the Cowichan Valley, on Vancouver Island, today, to photograph
the low elevation Erythronium grandiflorum.

The front plant in the first photo has two flowers on the stem - something we have never seen
 before with this species (though E. oregonum can have half a dozen or more).

I will take some close-up photos later in the week.
