Hi, valleylynn,
The plant you referred to as "Androsacea draba" seems to be a bit of a mystery, as that's not a valid species name.
Has it actually turned out to be in the genus Androsace (as one would be able to tell from the flowers)? I wonder if it is not actually Arabis androsacea... the mention of "Draba" might have been someone's guess to explain the four-petalled flowers, if so.
Anyway, nice plant, whatever it is.
Here's Arabis androsacea for comparison:
