Also known as Glorybower or tropical bleeding heart, Clerodendrum bleeding heart (Clerodendrum thomsoniae) is a sub-tropical vine that wraps its tendrils around a trellis or other support. Gardeners appreciate the plant for its shiny green foliage and dazzling crimson and white blooms. Water the plant frequently during dry weather; the plant requires consistently moist, but not soggy soil. Clerodendrum bleeding heart needs frequent fertilization to supply nutrients required to produce blooms. Feed the plant a slow-release fertilizer every two months during the blooming season, or use a water-soluble fertilizer every month.
Clerodendrum thomsoniae is a heavy feeder. To produce profuse flowers through the growing season, apply either a slow release-type fertilizer with micronutrients every two months or a liquid water-soluble fertilizer with micronutrients monthly. As Clerodendrum thomsoniae grows its thirst grows with it. A clerodendrum vine that occupies a three-foot trellis can drink several gallons of water weekly.
