Title: Thlaspi montana?
Post by: maggiepie on March 21, 2010, 08:06:47 PM
I grew this from seed last year, up until a few days ago it was still under snow.
I did have a few other thlaspi seedlings but can't find the tags and have forgotten what they were.
Am hoping someone can ID this for me.

Can't help with ID Helen, but they're very nice. They look as if they may be scented? Not of cabbage though hopefully. ;D

Lesley, I don't think the montana grows in a mound like this plant. It's not the most attractive plant I've seen.
No idea if it is scented but will give it a sniff when the snow melts. Snowing again here with freezing rain to follow. You beaut!!
NOT!!

I don't think Thlaspi montana has toothed leaves, assuming the plant shown here is representative:

I think your plant may be an arabis.  I'd suggest comparing to Arabis caucasica (now A. alpina):

If no one IDs it before then, I think the seed heads should be very helpful: thlaspi (little flattened packets) vs. arabis (elongated siliques)... ?

Helen your picture looks like a larger version of our Thlaspi zaffrani, seed from Gothenburg Botanic.  I'll take a picture and post it soon.

Here's an old SRGC posting on Thlaspi zaffrani:
http://www.srgc.org.uk/smf/index.php?topic=3356.0

If you read the description within it, that is, the response to the ID question, T. zaffrani is described as having entire leaves (i.e. not toothed).  The plant in question (Helen's) seems to have distinctly-toothed leaves.  
The leaves are also described as being "auriculate to perfoliate" for T. zaffrani. On the plant in question, the leaves immediately subtending the flowers may be edging toward perfoliate... but it doesn't seem terribly convincing??

OK here we go.  Remember this is a tiny plant, first season of growth and I am not the best photographer in the world let alone the forum ::).  Bearing in mind the previous post I have tried to show the leaves which I consider might have their "milk teeth". Four shots of Thlaspi zaffrani.

Lori, thanks for all the information. I had a sniff at the plant yesterday and it doesn't smell good.
I'm not sure it will stay there long enough to get seeds. I have another plant labelled thlaspi montana which looks somewhat different. The leaves are more narrow and toothed.
Still, that might just be because the plant is smaller.

Shelagh, I would be very happy if my plant looked like your zaffrani. The flowers on my plant don't appear to be getting stems, the flower heads are just sitting amid the leaves.
Maybe mine is some sort of weed.
