🌱 【Plants】 on this land of Hong Kong are not only a part of the natural ecosystem, but are also deeply woven into our local culture and daily lives. Despite having a land area of just around 1,100 square kilometres, Hong Kong nurtures over 3,300 species of vascular plants, around 2,100 of which are native. Situated in a sub-tropical monsoon climate, this city features diverse landforms—including mountains, hills, wetlands, and coastlines—creating a rich tapestry of habitats. From evergreen broad-leaved forests and mangroves to grasslands and plantations, Hong Kong’s plant communities showcase stunning diversity and adaptability. The Feng Shui Woods (風水林) of ancient villages carry deep cultural meaning for blessings and protection, while Jacaranda, Queen’s Crape Myrtle, and Chinese Fan Palm lining urban streets bring vibrant colours and greenery to our concrete jungle. These plants act as guardians of nature and form part of Hong Kongers’ collective memory, shaping a unique landscape where ecology and culture intertwine.
