So far, positive. I fell hard for this tree when I saw a row of 5 of them swaying gracefully in the wind. The chartreuse leaves gave a glow to the otherwise-green surroundings. I had read of the suckering and I'll admit it put me off. I've planted my own row of 4 trees and am still keeping an eye out for suckering 5 years later. I've seen neighbors with enormous trees and have been told there is occasional suckering but if sliced off AT the root they don't recur for the rest of the year. Some trees, the nursery tells me, have an over-active hormone near the end of the roots which causes the suckering. They confirm cutting the sprout off at the root level, leaving NO sprout will keep it at bay. I've seen yards and fields left unkempt in the area and young trees are forming groves. ... read more

This cultivar differs from the species in the bright golden to chartreuse color of the foliage. It's also said to have reduced flowering. Plants in commerce are grafted on seed-grown black locust, so the root suckers will not have golden foliage.

The species is a thorny ornamental tree with beautiful, highly fragrant flowers in late May/early June. Long popular in Europe, here in the northeastern US it's all too often afflicted by leaf miner (which ruins the foliage) and locust borer. The wood is brittle and storms frequently leave lots of broken branches, requiring cleanup and pruning. The prolific root suckering can be problematic in gardens. All parts are poisonous except the flowers.

Perhaps best cut back annually, to maintain it as a shrub.

Black locust (Robinia pseudoacacia) is considered invasive by the Minnesota DNR
"Ecological Threat:

* Invades primarily disturbed habitats, degraded wood, thickets and old fields crowding out native vegetation of prairies, oak savannas and upland forests, forming single species stands.
* It reproduces vigorously by root suckering and stump sprouting forming a common connecting root system.
* It is native to the U.S. and occurs naturally on the lower Appalachian mountain slopes. It has been extensively planted for its nitrogen-fixing qualities and its hard wood."

Beautifull tree! Nice scented when it's blooming and lots and lots of bees. Spent flowers make a lot of mess though.

A fast growing tree with spines. It sometimes produces suckers. In June racemes of white, scented flowers hang from the branches. However this cultivar is grown for its outstanding lime yellow leaves. They are among the latest to appear in the spring, but contrast wonderfully with the dark wood of the branches and give a magnificent display through to the autumn, when they take on warmer golden hues before falling.
