Gardeners' Notes:

Silene vulgaris is not actually native to North America; it is an introduced species.

Neutral Toxicodendron On Jan 8, 2004, Toxicodendron from Piedmont, MO (Zone 6a) wrote:

This is a native North American wildflower, growing from southern Canada down to Missouri and Tennessee. I have seen it volunteering here and there at old homesteads, usually at the edge of some shade trees where the plants receive part sun, part shade. A friend of mine gave me a plant, but it died when I moved it to full sun, so I don't recommend that exposure. I saved some seed, which I am hoping will germinate this spring (sowed in the fall). This is not a very attractive plant because it tends to flop over (that is why I tried full sun), but the balloon calyxes are quite enchanting.

A low growing perennial from Europe.

Has greyish green, ovate to linear, hairless leaves which may have a wavy margin. Bears pure white, deeply divided petals which come out of a light brown inflated calyx. Sometimes the plants may be dioecious (being either male or female) so seeds may not be viable from a plant grown alone.

Flowers May-October

Loves a well drained, neutral to slightly alkaline soil in light shade, tolerating some sun except during the hot part of the day.

Quite tolerant of a range of conditions as long as the soil doesn't lie too wet. Self seeds with ease.
