Thanks for this explanation. You anticipated a question that I have
asked in the other thread, before seeing your message. It does, as you
say, seem surprising that A. oregana isn't cultivated more often. The
various forms of A. nemorosa are quite popular in UK.

Yes, and I am very grateful indeed for the seed you sent, which has
produced a young plant that has successfully over-wintered in my
greenhouse. Some more have germinated, too, from more recent sowing.

 It has wonderful succulent leaves, all basal, and rather

This seems to match all other reports except oddly a curiousl entry by
Farrer in 'The English Rock Garden'. He wrote, "Contrary to
expectations, A. palmata is perfectly hardy in England, and though in
nature a drought-loving species, it even makes happy shining masses in
weeping Westmoreland. It is a plant, accordingly, of conspicuous value
for the garden, where room can be allowed for it to spread, in some
sunny bank of deep rich soil, assisted with a little sandy peat, and
perfectly drained. But, indeed, even in Lancashire, one sees it growing
freely as a border plant on warm exposures".
This was 1928, so I am not sure what has become of all these banks of A.
palmata in Lancashire!

Have you found that it needs to be kept quite dry?
