Erythronium 2010

[Ed Alverson]

Is this species under pressure from forestry / human activity or is its habitat safe?

The species is endangered partly because of the limited distribution and small number of sites (only 14 small populations), but also a variety of other factors, ranging from habitat loss to ecological changes to trampling by wildflower enthusiasts.  In addition to the Wikipedia article that Rodger mentioned, there is more info on the web site of the Center for Plant Conservation at
http://www.centerforplantconservation.org/collection/cpc_viewprofile.asp?CPCNum=1838.  There is also a nice magazine article on the web at http://files.dnr.state.mn.us/natural_resources/ets/dwarf_trout_lily.pdf

Fortunately at least 4 populations are protected in parks or nature preserves.  At the site where I saw it, park managers had constructed a boardwalk along the edge of the population so people could see it without trampling the habitat.  So people in Minnesota are definitely working to preserve the species.

A very practical approach Ed! Always good to hear about sensible conservation practices.

Chris, that 3rd picture looks pretty much on the way to E. caucasicum don't you think?

[Hristo]

Lesley, I see what you mean though pollen is black indicating dens-canis, usual problem is I have never purchased E.caucasicum, this was purchased as a dens-canis cultivar, vegetative increase is strong pointing towards a dens-canis cultivar. The speckled red centre is making me lean towards something like 'White Splendour'. Maybe should take Ian Youngs bulb-log advice and just regard as dens-canis white form!

E. caucasicum has yelolow anthers. See picture something earlier on this topic.

These don't normally do well for me, but the late spring has encouraged the stems to lengthen before the flowers open. Two forms of Erythronium sibericum.

[Afloden]

The Lake Garda E. dens-canis is very nice. Wish I could make it back to north Italy in the spring.

 Here is E. americanum in flower in another area in the Cumberland Mountains. Not sure what is making the heavy flowering this year, but all the populations I have seen are flowering really well. Last summer was very moist and cool with only a few days above 90F.

Lovely sight, Anthony.
I know the feeling - out here they practically flower below ground level...

They are far better after cool winters.

Erythronium are now starting to flower well here in the warmer weather. Two portraits of plants in flower today, E. rostratum and E.umbilicatum.

Flowering today here in New Jersey

[Guff]

Well, I have leaves but no flowers on the test spot. The leaves are huge compared to some in another spot that have buds(4 plants I can see so far). I'm wondering if light conditions plays a factor? The spot with the four plants with buds is a dark spot.

I'm making a new bed this summer, I don't want them to take over the coum bed.
