Growing Crocosmia: A Guide to Planting, Care, and Enjoyment
Introduction
Crocosmia flowers are a vibrant addition to any garden, producing masses of sword-shaped foliage and brightly colored blooms. These striking plants are members of the Iris family and are native to South Africa. Their name comes from the Greek words for “saffron” and “smell,” referring to their saffron-like color and subtle fragrance.
Planting Crocosmia Bulbs
Crocosmia plants are grown from corms, which are similar to bulbs. To plant crocosmia bulbs, follow these steps:
- Choose a sunny or partially sunny location with well-drained soil.
- Plant the corms in spring, about 6 to 8 inches apart and 3 to 5 inches deep.
- Plant them in clusters for maximum impact.
- Water the corms well after planting.
Crocosmia Plant Care
Crocosmia plants are relatively low-maintenance. Here are a few tips for caring for them:
- Water your crocosmia plants regularly, especially during hot and dry weather.
- Fertilize your plants monthly with a balanced fertilizer.
- Deadhead spent blooms to encourage new growth.
- Divide your crocosmia plants every few years to prevent overcrowding.
Crocosmia Bulb Care
Crocosmia corms are hardy and rarely need to be lifted for winter, except in areas below USDA zone 5. In these areas, you can either:
- Plant the corms in pots and move them to a sheltered location for winter storage.
- Dig up the corms, dry them, and store them in a cool, dark place until spring.
Harvesting Crocosmia Flowers
Crocosmia flowers are ready to harvest when the lower blooms have just begun to open. Cut the stems and place them in 100 degrees F. water in a dark place for 48 hours. This will help the flowers last longer in a vase.
