Scarlet Gilia

Ipomopsis rubra (eye-poh-MOP-sis ROO-brah)

Family: Polemoniaceae Native Herbaceous (3-15 ft)

This native biennial wildflower is grown as a half-hardy annual though, through reseeding, it can remain in the garden for many years. Sow seed into lightly raked soil in the fall to propagate. Plants produce a fern-like rosette the first year and a flower spike the second. Cutting back the spent flower spike will force a second bloom. The bright red, showy, tubular flowers arranged to bloom downward on the thick spike attract hummingbirds. It prefers well-drained soil from gravelly to sandy or medium loam. It grows in full sun but can tolerate light shade and can be drought tolerant and deer resistant.
