Crocosmia, which are related to irises and gladiolas, are tough enough to survive in cold gardening climates. Most commonly found in shades of red, yellow and orange, the flowers bloom from mid-summer until October in most areas. They range in height from two to four feet and have tube-shaped flowers. They thrive both directly in the garden bed and in containers on patios and walkways. Crocosmia bulbs are actually corms, swollen pieces of stem the plant and roots grows from.

Step 1

Choose a well-drained bed in full sun for crocosmia. Build the bed up with compost 2 to 3 inches to improve drainage if necessary.

Step 2

Loosen the top 6 inches of soil with a hoe or shovel. Mix sand into compact soils if necessary to loosen.

Step 3

Dig planting holes 4 to 8 inches apart. Plant each bulb 3 to 4 inches deep from the top of the bulb. Plant so the pointed end faces up and the root end is down.

Step 4

Water thoroughly after planting, and keep the soil moist throughout the growing season.

Step 5

Remove leaves once they yellow and die back in the fall.

Tips and Warnings

  • In areas with severe winter cold and frost, dig bulbs up after the first frost and store them in peat moss in a cool location until spring.
