This tiny perennial is native to mountain ranges in southern Europe. I had just one seedling survive, and nearly missed witnessing its first bloom (in its second year of life), since the flowers are hardly conspicuous. I'm pretty sure it's misidentified, since online photos show a much more strongly tufting/cushioning plant. Perhaps our plant, whatever it is, will develop a more robust habit later in life; if not, I can find alpine plants with a stronger presence to take its place in the rock garden. So far, it's survived into a third year, and has established itself somewhat more strongly.

Visitors to this page have left the following comments| Janet | Jun 28, 2011 | I'm guessing this plant might be Alyssum spinosum. Like you, I ordered Petrocallis pyrenaica seed from the 08-09 NARGS seed exchange, and it definitely wasn't Petrocallis pyrenaica. Instead, it looked just like my plants of Alyssum spinosum.
I tried again with Petrocallis seed from the current year's seed exchange, and this time, the seedlings look right -- so it might be worth your while to try again.
Thanks for the pointer, Janet. So far, my plant doesn't look like the (nicer) online photos of the alyssum either, but I'll wait another year to see its mature habit to figure out its identity for real. |
