Spiderwort

Spiderwort is a perennial forb native to Blackland Prairie, Edwards Plateau, Post Oak Savannah, Pineywoods. It grows best in part sun with low water needs.

Spiderwort (Tradescantia ohiensis) is the first wildflower most Texas gardeners notice in spring. The blue-purple three-petaled flowers open in the morning and close by midday, creating a changing display from March through June. Each flower lasts one day, but new buds open continuously. The plant is native across a large swath of Texas and is commonly found blooming along roadsides in April.

Spiderwort is not on the ASPCA Animal Poison Control Center toxic plant list for dogs or cats. It grows 1-2 feet tall with arching strap-like leaves. The early spring bloom fills the gap between the first warm days and the summer perennials. Native bee species, including long-tongued mining bees, are the primary pollinators; they collect the bright yellow pollen from the characteristic yellow stamens.

Ecoregion notes for Texas. In the Blackland Prairie (DFW, Austin, San Antonio corridor, heavy clay): native and thrives. It is one of the few ornamental perennials that genuinely prefers clay; the moisture retention suits it perfectly. Bloom lasts longer in clay than in sandy soil. In the Post Oak Savannah and Pineywoods (East Texas, acidic, well-drained loam): native; give it part shade and consistent moisture. In the Edwards Plateau (alkaline, rocky): plant in dappled shade or north-facing beds with some afternoon protection. In the Trans-Pecos: not recommended.

Spiderwort goes dormant in summer after blooming. Cut the yellowing foliage back to 6 inches in July; new growth returns in fall and persists through the winter. For HOA contexts, pair with Black-eyed Susan and Mealy Blue Sage so the bed stays interesting after Spiderwort's dormancy. In good conditions it spreads by seed; thin volunteers if they exceed your planned footprint.
