Harsh paintbrush is a hemiparasitic wildflower that requires a host plant such as a native grass or perennial to thrive, making it challenging to establish in garden settings. Plant it in well-drained soil with partial shade and consistent moisture, always alongside a compatible host. It rewards patient gardeners with stunning scarlet-orange bracts that attract hummingbirds and pollinators throughout summer.
