Purple Paintbrush Seeds (Castilleja purpurea) Drought Tolerant

Add a splash of unique, jewel-toned color to your wildflower garden with Castilleja purpurea, commonly known as Purple Paintbrush or Downy Paintbrush. This striking native perennial (sometimes biennial) is a true Texas classic, prized for its brush-tipped bracts in shades of purple, maroon, cream, and yellow.

🎨 Why You'll Love It
Unlike its fiery red cousin (Indian Paintbrush), Purple Paintbrush shows off soft, painterly bracts in dusky purples, wine-reds, and creamy yellows — giving it a softer, more unusual look that stands out in any native planting. Its fuzzy gray-green foliage and clustered blooms add texture and old-world charm to prairies, rock gardens, and naturalized beds.

🌱 A Note on Growing Paintbrush
Like other Castilleja species, Purple Paintbrush is hemiparasitic — it grows best alongside companion plants (native grasses like little bluestem or gaia/blanketflower work well), tapping into their roots for extra nutrients. For best results, sow near an established native grass or wildflower companion rather than in isolation.

🐝 A Pollinator & Hummingbird Favorite
The nectar-rich, tubular blooms are a favorite early-season stop for hummingbirds, bees, and butterflies, making this a wonderful addition to any wildlife-friendly garden.

✨ Perfect for native prairie restorations, rock gardens, wildflower meadows, and anyone looking to add a rare pop of purple to their spring blooms.

Germination: Best sown in Fall near a host plant, such as Little Bluestem. Seeds need 60-90 days cold stratification.
