Gardeners' Notes:

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

Much like the similarly invasive Norway Maple (Acer platanoides). Both are common weed trees of neglected urban neighborhoods. Both outcompete anything that tries to grow beneath them. Frost usually hits the foliage before it can turn yellow.

Planting is prohibited in Massachusetts and Connecticut, as this tree invades and impoverishes natural habitat in eastern North America and the Pacific Northwest.

Neutral melody On Nov 12, 2004, melody from Benton, KY (Zone 7a) wrote:

European in origin, sometimes escaping from cultivation here in the States. It is simply known as Sycamore on the continent, while our American Sycamore is known as Planetree there.

Resembling the Red and Silver Maples in looks and habit, it can grow to as much as 100'

Neutral smiln32 On Nov 9, 2004, smiln32 from Oklahoma City, OK (Zone 7a) wrote:

Deciduous tree with upright spreading branches. This tree is easily transplanted and prefers full sun to light shade.

It does have a number of pests which like it, (clearly a negative), though.
