Is anyone growing Petrocoptis pyrenaica? I am curious about its cold tolerance. I grew Petrocoptis pyrenaica ssp glaucifolia recently, producing several plants, but with zero success at over-wintering. It is a beautiful thing that blooms in the first year from seed and constantly throughout the season, so it was not a total loss, but I'm wondering if it's worth trying again? If you have experience with it, I'd love to hear about it.

Re: Hardiness of Petrocoptis pyrenaica?
Petrocoptis have not been long lived for me: I haven't grown them in a long while and this may prompt me to try them again. I generally remember them lasting two to three years max.
A classic example of an alpine best grown from seed. I don't ever recall seeing these offered by a mailorder nursery in the USA.
This is my first post!
Re: Hardiness of Petrocoptis pyrenaica?
Well, being the indefatigable optimist that I am about growing plants, 2 to 3 years in your area, Kelaidis, makes it sound to me like I should be trying it again!
I got the seeds from the NARGS seedex... and do I recall correctly that they were offered by someone again this year?
Re: Hardiness of Petrocoptis pyrenaica?
I grew this plant last year from Seed ex seed. Wintered it over in the garage and it went over except that it had nice green tips on all the stems. I put it in the greenhouse in mid March and it promptly died. I did save seed and have a few seedlings started to try again this year.

Well! Hard to know what to make of that kind of behavior, isn't it?
Re: Hardiness of Petrocoptis pyrenaica?
After reading this thread two years ago, I put Petrocoptis pyrenaica seed on my want/watch list. I ordered NARGS seed in the second round last year and planted a couple weeks ago in room temperature. They are up now.
Not really remembering well why I wanted I, I googled the name and guess what came up first on the search... this thread!
So any more follow up info? . . . Lori, Harold, Trond, Panayoti, anyone?

Sorry Rick, I've never tried this one! But according to RHS Dictionary of gardening Petrocoptis (which is the Greek equivalence of Latin Saxifrage!) is hardy down to -10 - -15C protected from excess winter wet (nothing for me then ;)). Can be expected to flower first year from seed and often grown as an annual.
Re: Hardiness of Petrocoptis pyrenaica?
Survived here for me this Winter with very dry cold (-10c) but not last Winter when it was much wetter. In the Alpine house it keeps easily. Try Petrocoptis crassifolia if you can get it.
Re: Hardiness of Petrocoptis pyrenaica?
Well, I have one seedling of Petrocoptis pyrenaica ssp glaucifolia to give it another shot with, so it better work! :D
I'd love to try Petrocoptis crassifolia, especially if it should have a better chance of overwintering.
Lori, I only saw them in the lower altitudes regions of the Pyrenees so I will guess they are not particularly hardy, especially in a zone 3-4. Even if they were, they are short-lived. Anything that flowers in the first year from seed is apt to be short-lived in the long term. Yours is such a lovely plant it may be worth growing simply as an alpine annual.
