Title: help...
Post by: David Pilling on June 11, 2011, 10:22:43 PM

Hi,

I'd appreciate any help with the specimen below. It came from Seed Ex 2008, and it has taken the intervening years to reach flowering size. It's quite a bright yellow. The leaves are big, the one at the bottom of the stem shown is around 12 inches, and for the years it has been developing it has had one or two of these big leaves. The flowering stem is about three foot high.

A species of Cremanthodium, David?

There are well over a hundred species, so investigation will be interesting!   :D

Susan thanks. Lots of info on the forum page you reference. The leaves of my plant have the same character as those shown in your last photo, crem3leaves.jpg but larger. You say that is like Cremanthodium ellisii, which it is, but not quite the same as the photos I've found on the web.

If I've mixed up labels, I got these as Cremanthodium arnicoides from the AGS Seed ex, 19/12/2007. I've been assuming I didn't mix things up, hence the useless subject line, in which case they were senecio jacquemontianus SRGC Seed ex 23/1/2008.

Anyway, wonderful to have some help.

From Magnar Aspaker's photos, arnicoides seems to be a smaller plant.
