Fire King Crocosmia stands 24 inches tall. The dark green foliage is sword shaped and appears before the flower stalks. The flowers of Fire King Crocosmia are a brilliant fire red, hence the name.

Type of Plant

Fire King Crocosmia is a perennial grown from bulbs. The bulb stores food for the plant until it starts to send up leaves and roots. Every year a new bulblet will be formed from the original bulb. Both should stay viable over winter with proper care. The scientific name for Fire King Crocosmia is Crocosmia crocosmiiflora.


Plant Fire King Crocosmia bulbs in the spring. The pointy part of the bulb should face up. Add one teaspoon of bone meal to the planting hole. There is no need to water. Cut spent blooms before they form seed heads. This will allow the plant to store important nutrients in the bulbs in order to over winter. In the fall, cut back the foliage after it turns yellow. Lift the entire bulb out of the ground prior to winter if you live in a zone other than 5a to 9b. Pack in straw or sawdust and store in a dark dry place where temperatures are around 50 degrees Fahrenheit.


Fire King Crocosmia is hardy from USDA Hardiness Zones 5a to 9b. This range covers most of the continental United States. However, if the bulbs are lifted and stored out of the ground for the winter, then you can grow them pretty much anywhere. South of zone 9b, plant in the fall for spring bloom.
