Black dalea is well adapted to hot microclimate locations in the Inland Empire where it thrives in sun and with normal winter rainfall and low amounts of summer water. It is a colorful flowering accent shrubs for courtyard and southwestern plantings in both commercial and residential settings. Monthly deep watering from spring through fall will enhance its spring flowering cycle and help maintain good foliage character. It should be noted there are several months marked by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water depending upon exposure conditions and size.
