Northwestern indian paintbrush
Castilleja angustifolia
Northwestern Indian paintbrush is a stunning native wildflower known for its vivid scarlet-orange bracts, but it is hemiparasitic and must be grown alongside compatible host grasses or perennials to thrive. Plant it in well-draining, rocky or lean soil in a location with partial shade to full sun, and pair it with native bunchgrasses for best results. It is a specialist plant that rewards patient gardeners with spectacular color and is a magnet for hummingbirds.
