Mimulus aurantiacus

Native to southern Oregon, California, and Baja California. Grows to 4 1/2 ft. tall and wide, with narrow, 1 1/2-in.-long, sticky dark green leaves. Buff-toned orange, 1 3/4-in. flowers bloom over a long spring-and-summer season. All subspecies thrive in full sun or partial shade, with little water.

More important than the subspecies themselves are the showy hybrids derived from them (often called Verity hybrids, after their originator). These plants grow 1–4 ft. tall and wide, with narrow, glossy dark green leaves that are sometimes sticky. Flowers are 1–3 in. long, in colors ranging from white and cream to yellow, orange, copper, salmon, red, and maroon.

Plant in full sun or light shade; give good drainage. Prune in spring before growth starts. Pruned again after first flowering, they often rebloom in fall—and, if given moderate water with good drainage, they may flower repeatedly throughout the year. Because plants are not long-lived, take cuttings of your favorites; they root easily in moist sand.

Mimulus cardinalis

Native to dampor wet locales throughout much of the West. Grows to 2 1/2 ft. high and wide, with upright or sprawling stems and bright green, sticky leaves. Tubular, scarlet, 1 1/2–2-in.-long flowers bloom throughout summer. Give full shade in Zones 12 and 13, sun or shade elsewhere. Ample water.
