Negative coriaceous On Mar 13, 2014, coriaceous from ROSLINDALE, MA wrote:

The Wisconsin and Minnesota DNR's consider this species invasive, and Connecticut has placed it on its list of potentially invasive plants. It has naturalized in 4 provinces and 15 northeastern and midwestern states.

I planted a row of these for a hedge along the backyard fence for privacy from the neighbors. Mine doesn't set out seeds or sucker. I planted 2' tall plants and they were 6' tall in 2 years. The specs say they grow to 8' tall but I think they would get quite a bit taller than that. Fabulous red color in the fall.

Amur maple (Acer ginnala) is considered invasive by the Minnesota DNR
"Ecological Threat:

* It displaces native shrubs and understory trees in open woods, and shades out native grasses and herbaceous plants in savanna habitat.
* A prolific seed producer, Amur maple is becoming invasive in the northern U.S. Extensive wild populations have been found in Illinois and Missouri. It resprouts easily from the cut stump.
* Amur maple is a native of central and northern China, Manchuria and Japan, it was introduced to North America in the 1860s. It is still being frequently sold commercially as an ornamental, and for wildlife and shelterbelt plantings."

Neutral PerryPost On Mar 28, 2005, PerryPost from Minneapolis, MN wrote:

Beautiful fire red/orange/burgundy fall color. Grows and reseeds in many different growing conditions.

Not recommended near native or naturalized areas. A.ginnala varietes are being watched in Minnesota and other states as being potentially invasive. Seedlings have been reported showing up in private restored prairie plantings.

Thrives in the pollution and compacted soil of midwest city conditions. Weigh the potential risks before planting in rural areas.
