Together with the bluebonnet and pink evening primrose, Indian paintbrush (Castilleja indivisa) is a traditional sign of spring across Texas. Sometimes the flowers appear as early as February. In other years, they may dally until April or May, depending on the weather.
Given the plants’ reputation as a spring wildflower, I was surprised to find a substantial patch in bloom at the Brazoria Wildlife Refuge on July 22. Wildflowers can be unpredictable, of course. There had been some rain, and I supposed the moisture might have led to some seasonal confusion for the plants. But when I returned a week later, even more paintbrush were blooming, and young plants were scattered along several roads.
Then came a second surprise. Consulting my new favorite field guide, Michael Eason’s Wildflowers of Texas, I found Indian paintbrush described as both a spring and summer bloomer. Why Eason extended the flower’s bloom time into the summer months I can’t say, but these plants, at least, suggest he was right to do so.
