These are fast growing trees that produce beautiful purple blooms in the spring (mine is blooming right now.) The wood is unbelievably lightweight and is useful in furniture making. Twenty years is considered the time it takes for it to get to harvestable size.

Some people grow them and cut them back every year, allowing it to grow an interesting habit that resembles a sunflower! But it won't bloom like that, of course.

This Royal Paulownia or Empress-Tree from China is similar to a Catalpa tree. Some classify it in the same Bignoniaceae Family as the Catalpa and others in the Scrophulariaceae that includes snapdragons. It is a fast growing tree of 3 to 4 feet/year, and a cut trunk can sprout and regrow to 8 to 10 feet/year. However, it is brittle and weak wooded, subject very easily to storm damage, plus it is very messy with dropping its big leaves, spent flowers, fruit, and dead twigs and branches. Its favorite feature is the pale violet flowers with darker spots and yellow stripes inside that resemble foxglove flowers in April-May for two weeks before the leaves, in panicle clusters 8 to 12 inches long, and having a vanilla-like scent. The flower buds are formed during the summer before blooming the next spring. The brown dehiscent capsule fruits persist and contain up to 2,000 tiny winged seeds. It is offered by quite a few cheap mail order nurseries. I've never seen it in my native northeast Illinois in USDA Zone 5a of the 1990 map. Morton Arboretum in Lisle, IL, reported in the 1980's that those planted there die to the ground most winters. They don't have any listed there now. I see it occasionally planted in a few landscapes in southeast Pennsylvania, but I see more having escaped cultivation and being an invasive tree along woodland borders or in pioneer tree forests. I have heard of some people growing a small plantation of this species to harvest its wood that is valued by Japanese and Chinese people to make bowls, pots, spoons, furniture, and coffins. Otherwise, it is not a good quality tree; better to stick with Catalpa that also is very messy.
