A perennial native wildflower with tubular scarlet-red blooms that attract hummingbirds. It prefers moist, shaded streamside sites and flowers from late spring through summer.

Why grow it

Scarlet Monkeyflower suits wet stream margins and boggy shade better than many related monkeyflowers, which prefer drier soil. Its red tubular flowers support hummingbirds in riparian plantings.

Watch out for

It declines quickly if the soil dries out in the growing season, so it needs steady moisture. Seedlings can self-sow freely in moist ground, and poorly drained soil may encourage root rot.
