The Hong Kong Orchid tree has large and beautiful purple blooms that occur from fall through winter. It is a great choice if you need a canopy tree to create some shade. Unlike other trees, the Hong Kong Orchid does not drop any seed pods, saving yourself from cleaning up an unsightly mess or from having to rip up seedlings. Also, hummingbirds absolutely love to use this tree's flowers as a nectar source. Here at the nursery, we've seen them happily zooming from flower to flower.
How to care for Hong Kong Orchid Tree
Light. Grows best in full sun.
Water. Water often while it establishes. Established trees have good drought tolerance, though leaf edges may brown in dry heat. Good drainage is important.
Soil and feeding. It grows in sandy, loamy or clay soil, acidic or alkaline. Feed with a granular fertilizer such as Bloom Special in spring, summer and fall.
Size. Usually 20 ft or more with a wide, spreading canopy; old trees can reach 40 ft. Plant it at least 8 to 10 ft from the house.
Pruning. Prune young trees at regular intervals to build an even crown. Multi-trunk trees can split at the crotch, so favor one main trunk. Raise drooping limbs for clearance.
Problems to watch. Chinese rose beetles may chew the leaves.
Good to know. Flowers appear from about November to April. It is sterile and drops no seed pods. Frost damages the leaves, and trees often die below 26°F.
