Montbretia was a hybrid between two species of this lovely South African genus, a cross aimed at producing a select plant with adequate hardiness. Crocosmias are corms; each year, a new corm builds up on top of the old one, taking its energy from this year’s foliage.
How do you keep Crocosmia blooming?
Water your crocosmias once weekly during the growing season, so the soil remains evenly moist. Remove spent blooms to encourage new blooms. Cut the stems back to where they meet the leaves. After blooming is over, keep the leaves so that the plant can put its energy back into its bulb for next summer’s blooming.
When can I plant Crocosmia bulbs?
