From the Greek mimo, ape; the flowers were thought to look like a mask or monkey’s face (Scrophulariaceae). Monkeyflower, monkey musk, musk. A genus of hardy annual, half-hardy perennial, and hardy perennial plants grown for their showy flowers. They are found in many temperate parts of the world, particularly North America.
Annual species do best in moist, shady positions, though they will grow in sunny places provided the soil is sufficiently moist. Propagation is by seed sown under glass at a temperature of 55-65°F (13-18°C) in spring. The seedlings are pricked out and gradually hardened off, finally in a cold frame, before being planted out at the end of May or the beginning of June. The hardy perennials grow well in the sun or shade, provided the moist soil. They should be planted from spring to early summer.
Propagation is by seed sown from spring to early summer in a temperature of 55-60°F (13-16°C), by cuttings of young growths inserted in sandy soil at almost any time, in a temperature of 55-65°F (13-16°C) or by division of established plants in spring.
