Native Wildflower of Texas :: Slim-Pod Milk-Vetch (Astragalus leptocarpus)
The Slim-pod Milk-vetch is part of the legume family (like peas) and makes a little tiny pod with a groove along the top. The flowers are teeny tiny at only 1/2 in. or 13mm long (this is a macro photo) and just lovely as a ground-cover with fern-like leaves.
In Texas, this flower is considered a perinnial although it's listed as an annual in the "Wildflowers of Texas" book by Geyata Ajilvsgi.
Attention: This plant is known to be toxic when ingested by cattle.
