Growing Crocosmia Plants In Your Yard
Crocosmia is a genus of flowering perennial plants native to South Africa. They are widely cultivated as ornamental plants in gardens all over the world in climates similar to that found in their native region. Crocosmia plants grow from corms, which are closely related to bulbs. Growing crocosmia flowers from corms is not different from planting bulbs. Both are simply underground storage organs for a plant, which contain the nutrients and embryo necessary for the plant to sprout. Corms differ from bulbs by the lack of rings on the interior but otherwise function in a similar manner. Crocosmia plants prefer slightly acidic soil. Make sure the garden bed is nutrient rich and well-drained, but lightly moist. Plant the corms in spring about 6 to 8 inches apart at a depth of 3 to 5 inches. Plant them in clusters for maximum effect. The corms will naturalize, or produce offsets, over time. Plant crocosmias in full to part sun for best results.
Crocosmia plants have few pest or disease problems and require no special maintenance. They are an easy addition to the home landscape and attract hummingbirds and pollinators. Crocosmia flowers are harvested for cutting when the lower blooms have just begun to open. Hold the stems in 100 F. (38 C.) water in a dark place for 48 hours. This increases the length of time the flowers will stay fresh in a cut floral display. Growing and caring for crocosmias is easy and once planted, you’ll be rewarded by beautiful blooms each year.
