Hey!I got some of this!I now remember planting it!
The 1st year I had it in shade under a cedar
tree& it got a lil morning sun for maybe 2 hours and was a leggy 12 inches.Hurricane Rita Retreescaped my cedar
tree& I guess this thing reseeded.It had a few light violet colored
flowers.Its been different this time.I didn't know what it was but looked your post.I knew I'd planted
seeds.I hope it reseeds like mad.
plant it in full sun or partial but more on the sunny side of life.I water mine daily& if wash the deck it gets watered then again.I think it would need protected from wind.
So if someone else stumbles in here.......I'm a mild climate.So my
seeds and maybe my roots overwinter.its also in a warm pocket area,(but maybe not now cause the
tree was retreescaped)My last frost in mostly in Dec.When do I need to sow for fall blooms& can I stagger
seeds planting time(like some hibiscus) for contuneous blooms?
