Tried to grow this from seed several years, with varying success, but a batch of seed started a few years ago finally yielded a couple mature plants this year. The leaves on this species are truly thread-like, giving the whole plant a fascinating appearance. Mature, well-grown specimens in a friend's garden looked much more impressive than mine, but I'm happy enough just to have it.

Visitors to this page have left the following comments| Mari | Apr 30, 2006 | Mine has no luck so far :-< A.tabernaeontane germinated v. easily (autumn sow, germinated in Apr) but this is the amsonia I wanted to grow in my shady woodland garden. The seeds were from Chiltern Seeds and have been in the pot for a full year and some months now! (from Berkshire, UK)
Amsonias certainly are tricky, and I've not always had luck getting them to germinate - whether that's because of seed viability or germination conditions is hard to say. Outside treatment does seem to be the best approach in many cases. |
| Pat W. Darwin, Mn | Nov 25, 2008 | Mine germinated(100%) this year after the 3rd cold warm cycle-when the temps were around 80f. Maybe they need it hot at the end?
I have found the same thing - after the cold treatment (just one is fine), they need a bit more than room temperature to germinate. Bottom heat, or other means of providing warmth, seems to do the trick. |
