Castilleja angustifolia Indian Paintbrush Seeds – Northwestern Native Wildflower – 100 Seeds

Castilleja angustifolia, commonly known as Indian Paintbrush or Northwestern Indian Paintbrush, is a striking native wildflower that brings vibrant color to prairies, meadows, and rock gardens. Its bright red to orange bracts resemble a painter's brush, creating a bold display from late spring through summer. This perennial is a beloved choice for pollinator gardens, native plant landscapes, and xeriscapes, attracting hummingbirds and bees.

As a hemiparasitic plant, Indian Paintbrush thrives when planted near host grasses or other perennials, forming a unique ecological relationship that supports a healthy garden ecosystem. Its drought tolerance and preference for well-drained soils make it an excellent addition to water-wise landscapes.

Planting & Care

Sow seeds in a well-drained seed-starting mix, lightly pressing them into the surface as they require light to germinate. Keep the soil consistently moist but not waterlogged, maintaining a temperature of around 65–70°F. Germination can be slow and irregular; patience is key. Once seedlings have several true leaves, transplant them outdoors after the last frost, spacing them 12–18 inches apart in a sunny location with well-drained soil.

Indian Paintbrush is hemiparasitic and benefits from being planted near host plants such as native grasses or other perennials. Water regularly during the first growing season to help establish a deep root system. Once established, it is drought tolerant and requires minimal care. Avoid overwatering and heavy mulching, as good drainage is essential for its health.
