Short-lived, subshrubby evergreen perennial, usually grown as a biennial. Dark green foliage. Bright red-orange flowers in spring. Flowers about two weeks earlier than "Siberian" wallflowers.

Cutting back hard after flowering will sometimes produce another flush of flowers in summer.
From seed, sown in midsummer. Also by stem cuttings.
