Astragalus racemosus

Silky Sophora Flowers 9888A

(Note: I significantly updated this article after I posted it.)

At Caprock Canyons State Park on April 15th I saw some plants that had produced clusters of pretty cream-white flowers, and there was also a tinge of pale violet in them that became apparent only with a close look. Also apparent with a close look were a couple of ants scurrying about on the flowers.

In preparing today’s post, I did some research and tentatively settled on Sophora nuttalliana as the identity of this plant. That’s the way the post went out, but then a comment and a link provided by shoreacres put me back into research mode. I now think the plant shown here is Astragalus racemosus, known as cream milkvetch. To see the places in the United States and Canada where Astragalus racemosus grows, you can check out the USDA’s state-clickable map.

If the name Astragalus rings a bell, it could be because I recently showed photographs of a flower and some leaves of an Astragalus species found in Austin.
