100 Castilleja integra Seeds - Wholeleaf Indian Paintbrush Native Red Wildflower for Meadow & Pollinator Gardens

Castilleja integra, commonly known as Wholeleaf Indian Paintbrush, is a striking native wildflower prized for its vivid red-orange bracts that resemble a paintbrush dipped in color. This perennial adds a bold splash of color to meadows, pollinator gardens, and native plant landscapes. Its unique appearance and ecological value make it a favorite among gardeners seeking to support local wildlife.

Wholeleaf Indian Paintbrush is a hemiparasitic plant, meaning it attaches to the roots of neighboring plants to obtain some nutrients. This characteristic makes it an excellent companion in mixed plantings with grasses and other wildflowers. It attracts hummingbirds, bees, and butterflies, enhancing biodiversity in your garden.

Planting & Care

Sow seeds in a well-draining seed-starting mix, pressing them lightly into the surface as they require light to germinate. For best results, cold stratify seeds for 30-60 days before sowing. Keep soil consistently moist but not waterlogged. Germination can be slow and irregular; patience is key. Once seedlings have several true leaves, transplant them into individual pots or directly into the garden after the last frost.

Wholeleaf Indian Paintbrush thrives in full sun and well-drained soil. It benefits from being planted near grasses or other perennials that can serve as host plants for its hemiparasitic roots. 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, as soggy conditions can lead to root rot.
