Hong Kong orchid trees

The Hong Kong Orchid Tree, which may reach heights of 20-40 feet, is characterized by a broad, circular canopy of huge, grayish-green leaves between 6 and 8 inches in diameter. People also call it Bauhinia x blakeana.

The vast, six-inch blossoms appear in a variety of purple, rose, and pink hues throughout the summer, fall, and early winter, when the garden is typically devoid of color.

This means that, unlike other Orchids, which may become a nuisance in the garden because of the long pods they produce after flowering, these blossoms are sterile and will not produce any offspring.

When it comes to urban landscaping, this Chinese orchid tree is the go-to option.

Pruning is typically necessary for the first few years following propagation to establish a more uniform crown in young Hong Kong orchids owing to their irregular shapes. Other caring tips are available if you scroll down.

Regarding the Hong Kong orchid tree problems, Blakeana is a sterile hybrid that will not reproduce. Trees in earlier landscapes would set off oodles of seeds, making them invasive and undesirable.

Their massive size makes them outdoor plants rather than indoor ones.

Its wood is naturally weak and susceptible to breaking in storms and other harsh weather.

Also, the wood is less thick, as is the case with all fast-growing trees, than a live oak, which develops more slowly. Do not put roots in a spot where the wind constantly whips about.

Bauhinia x Blakeana History: First Cutting

The story of purple Bauhinia blakeana began when Jean-Marie Delavay, a Catholic missionary belonging to the Paris Foreign Missions, discovered it on Mount Davis in Pok Fu Lam in the 1880s. 

In 1908, after being displayed at the Botanical Gardens and Hong Kong Zoological for the very first time, the structure received its formal Latin name – Bauhinia × blakeana –  and taxonomic status as a new plant species.

This plant was then introduced worldwide and eventually spread throughout Hong Kong after cuttings were distributed by the Botanical Gardens beginning in 1914.

Nowadays, it’s the official flower in Hong Kong. Tourists worldwide often have the soft spot for the first time seeing such a seductive plant.
