Prefers full sun and good drainage, and the habit is upright-spreading when given space. Can reach 60-70' tall and 30-50' wide.
Dirr reports this has been successfully used as an urban street tree in Philadelphia, Santa Barbara, and Paris (France).
Sometimes suckers and forms colonies. In some places it may self-sow. Its useful lifespan is 60-80 years.
Perfectly hardy in Boston's Arnold Arboretum (Z6a). The Morton Arboretum (Lisle, IL, Z5a) reports annual freeze injury. Dirr reports that it has not fared well in the hot summers at Athens, GA (Z7b/8a).
Hardwood cuttings root easily.
The lumber is fine-grained, reddish-brown, and valuable. It is considered a true mahogany, and valued in fine furniture and interior detail.
The young leaves and shoots are eaten as a vegetable in northern Chinese cooking, and sometimes considered a substitute for garlic. Red-tinted new growth is considered choice.
The tiny flowers aren't ornamentally significant. The woody seedpods are very beautiful when seen close up. The old infructescences fall off the trees in December and can be used in dried arrangements.
Growing moderately and suckering when the roots are disturbed. Little to no insect damage and appears to tolerate Cotton Root Rot (so far...Read More). pH 7.8 Montmorillonite Clay. Tolerates 100f for 30 to 90 days each Summer.
Pass Christian Z9a. I have 4 trees grown from seeds. The biggest is 4 ft. tall and, I think, 3 years old. The small ground planted tree...Read More dropped leaves during a summer hot spell, but recovered as conditions moderated. Keep in mind that my water table is down about 20 ft., my soil lacks humus, and it's difficult to maintain moisture in my soil. I put a containerized specimen with its base always in water, and the leaves maintained in 100 F . This showed me that the problem was lack of moisture with the ground-planted one....not high temperature. It's also tolerating soil ph of 5.5

Chinese Toon will never be a common name rolling off of the average gardener's tongue. It resembles for all the world a peeling-barked Ailanthus, which is not generally a winner in anyone's book. I can't say I ever noticed it when it flowered in all those years, but what I liked about this plant were the interesting dried husks left over after the seeds were released.
I've posted a picture of some of those husks that I collected over 10 years ago. They make great dried decorations (if your cats don't get them).
This tree has been mentioned as very tolerant of landscape extremes, and for having been used as a street tree in such diverse locations as Santa Barbara CA; Philadelphia PA; and Paris, France. So, there you go.
This edit added in June 2009: I traveled through Rochester NY in fall 2008, and at Durand-Eastman Park there are some wonderful groves of Chubese Toona. I didn't find many seed husks that I like so much; maybe there are a lot of playful cats there. Regardless, these were happy uncared-for trees hanging out in the woods with oaks, maples, and a lot of other trees. This park is on relatively sandy glacial soil on the shores of Lake Ontario, probably a solid zone 6a/5b.
