Distribution and Habitat

Catalpa bungei is native to northern China, including the provinces of Gansu, Hebei, Henan, Hunan, Jiangsu, Shaanxi, Shandong, Shanxi, and Zhejiang. It has also been introduced to Guangxi and Guizhou.

A collection has been documented in China’s Shaanxi Province at Nan Gong Shan at 1250 meters altitude by the Goteborg Botancal Garden.

Morphology and Growth Habits

  • Catalpa bungei is a deciduous tree growing to a height of approximately 10 meters (32 feet 10 inches). Some sources state 8-12m tall.
  • It is considered a small or even dwarf tree compared to other Catalpa species, making it ideal for smaller gardens.
  • Leaves are large, heart-shaped, triangular, toothed, and dark green.
  • Some varieties are grafted onto a Catalpa trunk to create a unique umbrella appearance.
  • It prefers deep, rich, and well-drained soil and can grow in sun or shade, but it is not suitable for windy locations.

Flowering and Fruiting

  • It flowers from July to August.
  • Some varieties bear fragrant pink-rose orchid-like flowers.
  • Other varieties may rarely, if ever, blossom.

Ecological Role

  • The Manchurian catalpa is tolerant of pollution, making it suitable for urban environments.

Genetic Information

  • Research is being conducted to reveal the self-incompatibility that exists within Catalpa bungei.
  • Studies have been done on the ectopic expression of a Catalpa bungei PISTILLATA homologue.
  • Research is being done on the dynamic changes of foliage growth of Catalpa bungei clones under different nitrogen exponential fertilizations.

Quirky Facts

  • Some believe that the aroma of the foliage keeps mosquitoes away from the garden.
