Indian Bean Tree
Catalpa bignonioides 'Nana'
- Indian bean trees are renowned for their broad, cordate (heart-shaped) leaves, and 'Nana' is no exception.
- Boasting huge mid-green foliage in a dense, bushy crown, this variety of Catalpa bignonioides adds huge levels of visual impact wherever it's planted.
- Unlike many Indian bean tree varieties, 'Nana' is small enough for gardens that are more limited on space. We'd recommend planting one as the focal point in the front lawn.
- Tolerant of pollution, this tree is an excellent choice for urban gardens where air quality levels are typically poorer.
- A top-grafted tree, 'Nana' has a distinctive, lollipop-esque shape with a spherical head of foliage and an upright trunk.
