Gardeners' Notes:

I have found this species to be the noxious weed that most others here have found it. It's one of the most aggressive weeds I know. In New Zealand, this species has been banned from sale, propagation and distribution.

The variegated cultivar 'Chameleon' is better known and more aggressively marketed, but all forms of this species are highly aggressive weeds. Resistant to most herbicides.

One other point: I find that this plant can self-sow. I have found a few seedlings as far as 30 feet away from the original planting. So don't count on a root barrier to confine its spread.

BONAP now reports this has naturalized in 8 states from Texas to Pennsylvania. It is invasive of natural areas, especially wetlands. ... read more

Caution: this plant is very, very invasive. If planted with that in mind, it is a delightful plant. The leaves are lovely and make a nice groundcover in season. In June-July the white flowers are beautiful. I have planted it both in a woodland setting and in dry shade and it flourishes in both sites.
