Gardeners' Notes:

I considered it for years as a pretty weed, easy to pull up, probably Eurasian. Then, I discovered that it is a native annual of eastern North America. Its foliage feeds caterpillars of several butterfly and moth species. It is the same genus as a number of ornamental tropical plants.

Southeast PA - I love this plant. It thrives in wet areas with some shade, not as much in drier areas. Easy to grow, reproduces from seed, very attractive, orderly look to foliage. Supports native insects.

I do not recommend this unless you want it to spread--if conditions are right, it will spread. I like it though, and I like that it helps shut out a number of undesirable plants, like stiltgrass, goutweed, and other invasives of wet areas.

This plant grows everywhere, sun, shade, it isn't picky. I spend all growing season ripping the stuff out of my flower beds. Yeah, it pulls up easily, but it is everywhere. And not just a plant here and there, it blankets the ground. I dislike it intensely and have been battling it for the last 7 years. Do not introduce this plant to your property unless you want to spend lots of time weeding!

Have seen this weed mostly partial shade - but will do well in sun - not as aggressive as some of the worst weeds but still bad enough - have succulent stems . Flowers is insignificant and this is easy to pull but produces lots of seeds.
