100 Seeds Castilleja integra Wholeleaf Indian Paintbrush Wildflower

Wholeleaf Indian Paintbrush is a clump-forming perennial wildflower known for its vivid scarlet-orange bracts that brighten dry, sunny landscapes. It is a favored choice for cottage gardens, pollinator plantings, and water-wise wildflower meadows, where its upright stems and bold color create a striking seasonal display.

This species pairs well with native grasses and other drought-tolerant perennials in rock gardens, borders, and naturalized areas. The colorful bracts appear from late spring through summer, followed by small seed capsules. It grows best in lean, well-drained soils and open, airy sites, and it can be established in containers or mixed beds with consistent moisture during early establishment. Provide good drainage and avoid overly rich soils for best performance.
