Erythrina X bidwillii -  Hybrid Coral Bean - Perennial - An extraordinary and spectacular perennial for full sun, which blooms from May until first freeze.   The long, tubular flowers are a brilliant red and occur in spikes at the top of 6- to 8-foot stems.  Once established, it requires no supplemental irrigation.  Being a legume, it never needs to be fertilized.  The only maintenance required in cultivation is to cut everything off at 4-inches above the soil-line after the first freeze.  Their recovery is rapid in spring.  The plants should be cut back even after a very mild winter to prevent them from reaching arboreal proportions.  It is the best natural hummingbird feeder for central & south Texas.
