Fastest Growing Shade Tree! Fast growing and able to establish itself in nearly any landscape situation, princesstree is breathtaking in spring when it is filled with fragrant, lavender and white flowers. A clumsy, widely-crowned deciduous tree from China, it produces copious amounts of leaf litter and seeds, increasing its ability to become invasive in many situations. Often it may be regarded as a "weedy tree" although stunning when in flower. In mid-spring, the tree's branch tips are filled with an upright, moppy cluster of small, trumpet-like flowers with five lobes. Colored lavender to lilac-purple, the throats of each blossom is a lighter shade, even pure white with yellow streaks. They smell of vanilla. As the flowering show ends, the large heart-shaped leaves emerge, sometimes having small lobes. In summer these leaves are shed on an ongoing basis, and the persistent tan fruits develop on the branch tips, eventually splitted and each releasing hundreds of seeds. There is no fall color on the princesstree. In winter the shallowly fisssured dark gray-brown bark is noticed, as are the muscular, heavy, horizontal branches. It is weak wooded and shallow rooted. Grow princesstree in full sun in nearly any soil type that is not waterlogged. It is best grown in deep, moist but well-draining soils and certainly protected from winds. Bitter winter cold can destroy flower buds and too warm of winters will lead to bud drop. Grow it in lawns where the flower and leaf litter is not annoying and the shallow root system is not troubling. It casts dense shade as well and does not create a setting for a garden underplanting. Investigate if this tree is regarded as an invasive that is not to be planted in your region. In many temperate areas outside its native China it has escaped cultivation and can be seen in waste areas, abandoned building sites and common roadside verges.
