Does Arabis alpina ssp.causica tend to self seed back to the species alpina. The self sown seedlings have hairy leaves different to ssp causica's smooth leaf. It has a seratted leaf still and is forming a rosette similar to the ssp.causica however(the flower stalk is similar flower not opened yet). I was wondering if it was just a crucifare weed,normal weed, or the true species alpina from my descriptions.
Hope you can help David.

Hello, David, welcome to the Forum. Hope we'll come up with an answer to you. Can't say this is something I know about..... :-[

David,
I do not know Arabis alpina ssp.causica, but Arabis alpina is very variable in flower size, stature and number of rosettes per plants. Perhaps you grow A. caucasica which is closely allied to and confused with A. alpina.
It is normal that seedlings are variable.

I can't help with this specific question either but on a different thread yesterday or the day before, there was a picture of a variegated arabis which I grow as A. ferdinandi-coburgi 'Variegata.' There is another form called 'Old Gold' with yellow variegation instead of white. Why I mention them here is because in their mats, both will occasionally produce some plain green leaves instead of variegated. These are not seedlings as one might expect, but sports. So maybe yours, David, is doing the same thing and sporting.
