A showy native wildflower with tubular scarlet-red flowers arranged in spikes that attract hummingbirds and other pollinators. It thrives in dry, sunny locations and is relatively short-lived but often self-seeds.

Why grow it

Scarlet Gilia offers reliable hummingbird and pollinator attraction in xeric gardens where many ornamentals struggle. Compared to other short-lived native wildflowers, its tubular flower structure is particularly well-suited to hummingbird feeding. It requires minimal water and soil amendment once established, making it a low-input choice for dry, sunny sites in its native range.

Watch out for

This species can take two years to flower from seed, so patience is needed before assessing establishment success. In areas outside its native range, monitor for any tendency to spread aggressively, as self-seeding behavior varies with local conditions. Poor drainage or excessive watering will shorten its lifespan considerably.
