Native to open woodlands in the southeastern United States, this bluestar has grey-blue flowers and lance-shaped leaves. Ours is taking a long time to develop – two full seasons after being started from seed, it still emerged as just a little whip of a plant in spring, and continues to live in our orchard nursery area. But it's starting to show more of its eventual habit, which is rather different from that of other amsonias we've grown: sparsely branched and leaved, looking almost like a little tree. I think I spotted some attempt at blooming in May of their third year, but it never amounted to much, and I failed to capture it on photo. But the following year, flowering was more assertive, as shown in the picture above. All in all, our plant looks a bit different from online photos of the species, so I'll reserve judgment as to its true identity until I've done some more research.

We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
