Texas paintbrush

Castilleja indivisa

Texas paintbrush usually blooms from early March to early May in the Texas Hill Country, with the best color from late March into early May. That's the only region we track it in so far — the ladder below shows where it falls in the year.

Each rung is one region's usual window; the deeper stretch is its best weeks. A rung lit violet has its window open this week. Based on reports from iNaturalist naturalists.
