There isn't a tremendous amount of information available on Clerodendrum. The Clerodendrum comes in a few different forms both vining and bush or small tree types, and a few that can go either way. Most of them would be considered tropical except for 'Bungei' pink. This variety can survive outside throughout the South and up into the northern coastal areas. Flowers and leaf shapes vary greatly from the familiar urn-shape to tight clusters of small florets and small slender leaves to large round ones.
All varieties grow well with an even balanced fertilizer program and are vigorous growers.
All the growers in south Florida grow their plants in full sun but they will tolerate some shade. Regular watering is best. Some of the varieties do display some drought tolerance, but for best performance and flower display, water regularly. For small to large containers these plants are usually trellised. Some are also grown as patio or landscape plants in 1-2 gallon pots.
