Crocosmias also known as Montbretias are fiery-colored perennials with lush green swordlike foliage. Their flowers are carried on arching, zigzag stems that are good for cutting. Many showy crocosmia cultivars have been created through crosses between related genera as well as among different species.
These hybrids vary in hardiness and are generally suited for zones 5 – 9. “Lucifer” has deep-scarlet flowers and is an extremely popular selection. Plant montbretias in the spring in moist, humus-rich soil in full sun. They spread to form tight clumps of beautiful foliage. Divide clumps in the fall. Thrips or spider mites may attack, causing white stippling of the leaves. Spray with an insecticide.
Plant crocosmias with other hot colors and deep purple plants for contrast. Choose coreopsis (Coreopsis spp.), Garden Phlox (Phlox paniculata), lavenders, goldenrods (Solidago spp.), and sages for border companions. Mass plantings are effective in front walls or fences or with flowering shrubs.
