A handsome, tough, adaptable shade tree that should be more widely known and grown. Championed by Michael Dirr.

Its habit varies widely from clone to clone, and it does not attain the stature or habit of the American elm. But many cultivars are being released with their own desirable qualities.

According to Dirr, there is no foundation for the common belief that this species is susceptible to ice, snow, and storm damage.

Some have expressed concern about its invasive potential. BONAP shows that it hasn't naturalized widely outside of southern California and Arizona. This species is often confused with the Siberian Elm, U. pumila---also commonly called "Chinese Elm"---which is considered invasive from central Mexico through central and eastern N... read more

I have heard that a new, very hardy lacebark Chinese elm has been developed that can withstand the high wind and severe ice storms in Oklahoma. One name may be "Easy Street". Another might be "Whit". I'm not having any luck in finding it. Does anyone know anything about it, or have any experience with it?
Elms grow like crazy here, to the point of being invasive, but they are prone to damage from wind and ice, and are not nearly as handsome or as shapely as the cultivated varieties.
I'd appreciate any information or suggestions on where I can find out more about the new one.

My next door neighbor has 2 of these. It is extremely invasive, drops little seedpods and leaves all the time, and grows very rapidly. The one in her backyard is right next to my garage, and grows so much that it scrapes the roof tiles and I have to ask her to get it trimmed every year. (she is nice about it) It NEVER loses all of its leaves; instead, it loses them throughout the year, and sheds seedpods mostly in the winter and fall. I cannot keep up with the seedlings it produces in my yard. If anyone knows how to kill this tree, please let me know. I hate it.

I lived in Buckeye, AZ. (Truly out in the Desert!), and the Lacebark Elm did great there. Now we have moved to Peyton Colorado, and I'm definitely going to give it a try here. The soil here is towards the sandy side, and really soaks up the water quickly. It's supposed to be slightly alkaline. My main worry is wind tolerance. I'll give a report later this summer as a follow-up.

Susceptible to mistletoe and to a fungal disease that attacks the vascular system and causes branch die-back and canopy thinning.

It is also invasive and has spread from cultivation in Texas and has the potential to be yet another exotic invasive. There are better alternatives! Please don't plant.

This is a highly invasive tree that sends out runners and sprouts. My neighbor had one in his yard and cut it down. In my yard I still have many sprouts growing that came up from his tree, despite my active and laborious removal of them. The sprouts quickly grow into trees. Be warned!

Planted one as a street tree, after 2 years of rooting it really took off last year and has nearly doubled in height after 4 years. I only watered it the first year, but I do fertilize with tree spikes every spring. It tolerates our poor clay soil, humid summers and winter road salt melt well. The bark is really neat. I have a zoysia lawn so no worries about seedlings. In the fall, one windy day and all the leaves are gone down the street, have yet to rake 1 leaf. A great tree-go plant one.

Our Lace Bark Elm tree has been wonderful. We're in OKC, and, it hasn't leafed out yet this year--we were puzzled. As many of you know, we had an unusual, relentless cold. snowy, and, moist winter. Generally, until now, it's certainly been moist since the summer of last year.

The tree has tiny buds now that seem to multiply daily; the small twigs they're on are very brittle, though. We see green in small branches, however. It hasn't been very warm yet at night (given spring storms and cold fronts); I think freezing is over, though.

I didn't want to do this, yet, my mother (whom I consider an expert on flowers and shrubs) said to water the tree "separately" with small sprinkler--I obliged. The ground is saturated now: Her stock answer (until now) still was to... read more

Planted this tree last fall. It's growing well. Not bothered by heat, did not suffer it's first summer. It grew about 2 feet, and is about 12 feet tall. Peeling bark looks nice on older trees. Will make a good shade tree in a few years.

My lacebark elm grew rapidly in the Dallas, Texas area. It is a good shade tree and is beautiful if trimmed yearly. I have not had problems with baby elms sprouting up, but the tree's small leaf size and abundance of blossoms create a large amount of debris to clear up each year. One year I left everything on the ground and my grass died. I clean it every year now and replaced my Bermuda grass with St. Augustine. My garden is once again in balance.

Have two large ones in the yard that came with the house, very invasive. Seedlings pop up everywhere in the yard faster than I can yank them.

i enjoy the sight of this plant, great bonsai,even for me, not invasive here, far less common than natural trees such as maple and oak.

I've seen this tree in nursuries.It is a very pretty tree,however it is from Asia and I do worry about it becoming another exotic invasive.I would have to be convinced it doesn't spread easily before I would plant it.

Commonly grown landscape plant all over Southern California showing its preferred temperature range goes up to easily 10b (can't comment on 11 since we don't go up that high here). Had one in the yard for years and it was a weed problem... little elms popping up everywhere. I can't give it a negative, though, as the weeds were easy to yank and it was a nice looking tree.. a bit too common here, though... if well pruned is an excellent specimen tree.
