Plant Profile: Bauhinia x blakeana

This broadleaf tree is a hybrid, semi-evergreen species characterized by multiple trunks and an umbrella-like shape with an irregular crown. Its large, orchid-like blooms display a spectrum of colors, ranging from reddish hues to pink, and measure between 5 to 6 inches in diameter. The foliage is gray-green and exhibits a somewhat deciduous nature, shedding leaves later than one might anticipate. This tree thrives in full sunlight and adapts to various soil types, though it requires good drainage. To prevent damage, it is advisable to shield it from frost, as it cannot withstand prolonged periods of severe cold. It is best to plant it in a sheltered area to protect it from chilly winds.

During its early growth stages, regular pruning is recommended to promote a more uniform crown as the tree matures.

This sterile hybrid does not produce seeds, meaning there are no seed pods to manage. Propagation is limited to methods such as cuttings, layering, or grafting onto seedlings of one of its parent species. All existing specimens are descendants of hybrids developed at the Hong Kong Botanical Gardens. The absence of seed pods enhances its appeal compared to other trees that shed pods and require cleanup.

While it typically grows as a multi-trunked plant, it can be trained to develop a single trunk. However, if allowed to grow with multiple trunks, the tree may become prone to breakage at the crotch as it matures.

Surface roots are generally not an issue.

This species may be mistaken for Bauhinia purpurea.

In terms of pests and diseases, the Chinese rose beetle can cause leaf damage. As the tree ages, its branches may begin to droop, necessitating pruning to maintain clearance beneath the canopy.
