A deciduous tree prized for its large heart-shaped leaves and fragrant purple-pink flowers that appear in spring before the foliage emerges. Grows rapidly and makes a striking ornamental specimen, though it can self-seed prolifically.

Why grow it

Princess tree offers rapid early growth and substantial foliar mass, making it useful for quick screening or temporary shade in settings where fast establishment is valued. Its spring flowers appear before leaf-out, providing early-season ornamental interest. Compared to slower-growing shade trees, it reaches useful size in a few seasons, though this speed comes with the trade-off of generally shorter lifespan and weaker wood.

Watch out for

Branches are brittle and prone to storm damage, particularly in windy sites. Growth is indeterminate and can become leggy without early structural pruning. The tree flowers prolifically but inconsistently year to year depending on winter severity and spring timing.
