I plunked 2 into the ground and left 1 in the pot, exposed to the elements in our zone 8 environment. The one in the pot didn't survive the -10 c winter. But the two little ones in the ground survived, grew to nearly twice the size this year and actually flowered in late summer and fall. I didn't know that they would flower while the plant was so small. Couldn't see any seeds though.

Can't wait to see what the plants look like next year.
