Botanical Name: Crocosmia 'Emberglow'
Common Name: African Sword Lily, Montbretia
Bloomtime: June to August
Flower: Showy, Good Cut
Plant Height: 24 to 30 inches
Foliage: Dark green, sword like
Plant size: Dormant Bulb 10/+cm in circuference
Requirements: Full Sun or partial shade. Average, well drained soil. Medium moisture.
Suggested use: Hummingbird garden, Perennial border
USDA Hardiness Zone: 5-9 (zone map below)
Grow in medium moisture, moderately fertile, well-drained soil in full sun to part shade. Prefers full sun, but appreciates part shade in hot summer climates. Plant corms in spring after last frost date approximately 3-4” deep and 6” apart. Not reliably winter hardy in USDA Zone 5 where it needs a protected location and winter mulch. In order to insure winter survival in USDA Zone 5 and perhaps Zone 6A, digging up the corms in fall and storing them in a dry medium over winter (in somewhat the same manner as gladiolus) is an option that may be considered.
Crocosmia is a genus or about 7 species of cormous plants from grasslands in South Africa. Montbretias are good fresh cut flowers which are frequently used in commercial flower arrangements.
Genus name comes from the Greek words krokos meaning saffron and osme meaning a smell for the smell of dried flowers steeped in warm water.
'Emberglow' features sword-shaped, basal foliage (2-2.5’ tall) which resembles gladiolus or iris and nodding, tubular, somewhat star-like, burnt orange flowers (1-2”) which appear in summer above the foliage on the upper portions of arching, often-branched scapes.
