Sphenodesme belongs to a group of flowering shrubs and small trees that thrive in warm, humid conditions, preferring partial shade. They require consistently moist, well-draining soil with regular watering, yet are sensitive to waterlogging. Gardeners may face challenges with pests like aphids and diseases such as root rot. Seasonally, sphenodesme demands protection from extremes—less water in winter, increased humidity in summer, and shelter from harsh sun. Regular pruning maintains health and shape, particularly after flowering seasons.
