Texas Toadflax - Nuttallanthus texanus

Texas toadflax is one of three species of native North American toadflax, the other two being N. canadensis and N. floridanus. Depending on location, the native range of these three species can overlap.

Texas toadflax is native to the southern United States and is naturalized (as a plant that naturally occurs in the area but is not native to the area) in large areas of the northern United States.

Like the other Texas Toadflax Nuttallanthus texanustwo species of toadflax, Texas toadflax is an annual that produces light blue flowers in the spring. Found wild in open woods and prairies, Texas toadflax is a usefull addition to woodland or naturalistic gardens.

If left to go to seed, Texas toadflax will reappear in the garden although its exact location in the garden will become unpredictable. It is therefore not the best choice for gardeners who like to exert control over their planting schemes.

Importance as a caterpillar food source: The Common Buckeye feeds on Texas toadflax leaves. The dark green eggs are laid individually on the leaf buds or on the topside of the leaves.

Importance as a butterfly nectar source: A good nectar source that also attracts many pollinators in addition to butterflies.
