Today I found out that these seeds I collected from supposedly A. Circinatum are starting to sprout. Last October I sowed these seeds into a small tray filled with my garden soil, and left the tray to over winter near one of my in-ground fig tree, protected by a snow pile. The snow pile thawed ca two weeks ago. And now I see the first three sprouts! I will up pot the content of the tray into a deep container right now, to let roots freely develop. It's a pity, that palmatum did not produce any seeds last fall.'
