Chinese flame tree

Chinese flame tree (Koelreuteria integrifolia) is a distinct species belonging to the Sapindaceae family. Known for its aesthetic appeal, this tree is a popular choice for ornamental purposes in gardens and landscapes, providing a stunning visual display of flowers and seed pods throughout the late summer and autumn.

Native to South-Western China, the species has a long history of cultivation in East Asia. It naturally inhabits mountainous forests and valley slopes. Due to its hardiness and environmental flexibility, it has been introduced to various temperate and subtropical regions across the globe.

The tree is characterized by its pinnate leaves and magnificent panicles of yellow flowers. Following pollination, the tree develops papery, bladder-like capsules that protect the seeds and persist on the tree, adding texture to the landscape. Its growth habit is generally spreading, creating a canopy that provides moderate shade.

Regarding cultivation, this tree thrives in full sun and well-drained, fertile soil. While it shows good resistance to drought once established, young saplings require consistent moisture to develop a strong root system. Pruning should be carried out primarily for sanitation and to shape the crown during the dormant winter period.

Economically and horticulturally, Koelreuteria integrifolia is primarily valued for its utility in urban forestry and landscape architecture. It is known to be relatively tolerant of urban pollution. Furthermore, it serves as an excellent source of nectar for bees during the peak of summer, contributing to local biodiversity.
