Grow in average, medium moisture, well-drained soil in full sun to part shade. Prefers moist soils in full sun. Plant corms in spring 2-3" deep and 6-8" apart. Only reliably winter hardy to areas where winter temperatures do not dip below 0 F. In USDA Zone 5 (and possibly Zone 6), it is strongly recommended that the corms be dug up in fall and stored over winter in somewhat the same manner as for gladiolus (but do not allow them to dry out completely). Propagate by division or by corm offsets. Tolerant of summer heat and humidity.
This montbretia cultivar is an Alan Bloom hybrid (Crocosmia x Curtonus) which has flowers and foliage that are similar to gladiolus. A clump-forming plant that features tubular, nodding, scarlet red, one-sided flowers borne along the upper portions of stiffly arching, sometimes branched, flower scapes (stems) typically rising up to 3' (infrequently to 4') tall and slightly above the narrow, sword-shaped, basal leaves. A good fresh cut flower which is frequently used in commercial floral arrangements.
Spider mites can cause significant damage to the foliage, and, if left unchecked, impair normal flowering.
Best when planted in clumps of 12 or more. Provides color and contrast to the perennial border. May be grown in containers where lifting in winter is perhaps easier.
