Gardeners' Notes:

I got some of this from a friend's property but began yanking it after the bees didn't show any interest in it. I plant my native gardens for pollinators. NOW, I read that it's a host plant for Hummingbird Moths and Monarchs.

I'm giving it a positive for this reason. Of course, it's easy to grow :-) and it provides necessary hosts plants for some our most treasured wildlife species.

This plant is not the best choice for fussy gardeners. It is a plant, it has a mission, and it travels quite well. In fact, it very much reminds me of the growth patterns of running bamboo. Many feet from the mother plant you will find shoots popping up here and there.

I don't mind it, I simply run over the unwanted with the lawn mower. Yes, it will grow back, but not worth getting terribly excited about.

Neutral melody On Jan 23, 2005, melody from Benton, KY (Zone 7a) wrote:

All parts of this plant are poisionous, and it needs to be kept from livestock and children.

A common fence row plant, it thrives in sunny, overgrown locations.
It needs to be pulled out before it sets seed.
