Crocosmia, sometimes called montbretia, is a member of the iris family and is native to Africa. This plant has sword-shaped leaves and red, yellow or orange blooms that appear during mid-summer and early fall. The blooms draw an abundance of hummingbirds to the garden and are long-lasting in cut flower arrangements. Crocosmia does best in full to partial sun and well-drained soil. It can be planted in containers and is hardy in USDA zones 6 through 10.
Dig a hole 3 to 5 inches deep with the garden spade and plant the crocosmia corms, which are the bulb-like roots, with the pointed ends directed upward. If you are unsure about which end should be up, plant the corm on its side.
Water until the soil is well-moistened, but not waterlogged. Continue to water anytime the top inch of soil feels dry. Growth should begin in two to four weeks.
Water crocosmia even after the blooms have faded. Stop watering after the first fall frost. Clip off the leaves with pruning shears once they have turned yellow.
Dig the bulbs after the first fall frost if you live in a region that experiences extremely cold winters. Place the corms in a single layer and allow them to air-dry completely. Put the corms into a paper box filled with peat moss and leave them there until all danger of spring frost has passed. Replant them in the garden.
