I'm not sure about the identity of this one. It grew from the same batch of seed as our Thermopsis villosa, but is clearly a different plant: it blooms about a month earlier (in early May, instead of early June), has pointier leaves, and its flowers are arranged more sparsely along the flower stalk. All in all, a very nice plant. The tentative ID comes from helpful Gardenweb suggestions. If you believe it's incorrect, please leave a comment below.

Visitors to this page have left the following comments| Karen | Jan 02, 2006 | I'd like to know the name of the woody plant behind the yellow thermopsis! Thanks...
That's spirea. |
| Liz | Apr 28, 2008 | Hi Rob! I'm a newcomer to your website and am looking forward to your plant sale this weekend! I have this plant blooming in the garden right now-bought it at the end of the season and had no idea what it looked like. It only had the label "Carolina Lupine", no latin term : (((
Carolina lupine is normally used as the common name for Thermopsis villosa - but in my experience, that one blooms later. |
| Meredith | Jan 24, 2009 | It looks like Thermopsis chinensis to me. |
| T. Skinner | Apr 26, 2009 | Is this plant invasive? I thought lupine is on the USDA list of invasive weeds.
Invasive species lists go by botanical name, not by common name - the same common name can be applied to many species, differing greatly in their native status and aggressiveness. As for this plant, I find it not at all invasive in our climate: doesn't spread by roots, and I've not seen volunteer seedlings. |
| Casey | May 08, 2009 | Do you know where I could purchase this plant. I have Baptisia in dark purple and in white and would love to have some of the yellow. |
