Story and Photos by Yvonne Lelong Bordelon
Giant Turk’s cap is the larger tropical cousin of the popular hummingbird and butterfly plant, Turk’s cap (Malvaviscus arboreus). The bright red, 2-inch flowers of giant Turk’s cap droop downward and never fully open.
This multi-stemmed, low-maintenance tropical evergreen shrub is deer resistant and drought tolerant. Use it as a specimen plant in hummingbird and pollinator gardens. In most of Louisiana, it blooms in fall until it is killed back by the first winter freeze.
The tough fibers of its bark are used in weaving and making cord. Good companions include winter shrimp plant (Justicia brandegeeana), firespike (Odontonema strictum), flowering maple (Abutilon pictum), and tropical milkweed (Asclepias curassavica).
