Gardeners' Notes:

Negative coriaceous On Jun 15, 2014, coriaceous from ROSLINDALE, MA wrote:

This toxic plant invades natural areas and suppresses other vegetation. Its roots reach down 12 feet or more, and once established it is very difficult to control. It spreads both underground and by seed.

Its cultivation is prohibited in ten states and it has been declared a noxious weed in twelve others. This species is naturalized in most states and provinces of North America except the US southeast.

I observe a vigorous local stand prospering in mostly shade. Clearly it's as highly adaptable about light as it is about most conditions.

Invasive! Invasive! Invasive! This little brat of a plant is growing in a dry, mostly shady location and I cannot control it. The best thing I can say about it is that it comes out of the ground easily.
