As you can see on my photos, Allium ursinum can be a very invasive species here in Austria, but thats ok, because it is a native plant here.

A plant of moist woodlands native to much of Europe and northern Asia, traditionally gathered and eaten cooked or raw. It is also used in folk medicine. It resembles several poisonous plants, and in Europe poisonings occur regularly when the wrong species is eaten.

Very similar to the North American A. tricoccum, which is traditionally eaten and celebrated in the folk tradition of the southern Appalachians, and has the same common names.

The foliage disintegrates shortly after flowering as the plant goes summer dormant.

Spreads invasively both by self-sowing and by rhizomes underground. The species has been declared a noxious weed in Arkansas, though this may be due to ill-informed legislation. BONAP and the USDA Plants database do not show any ... read more

This is a great plant for a shady garden but you MUST remove all the seed pods. This plant produces hundred of seeds and they all seem to germinate. If you don't deadhead you will find this EVERYWHERE.

Just an FYI: reading up on this plant and saw it listed as a noxious weed in some areas- probably best to research before planting.

In March I ordered thirty plants and was given a 15 day shipping window starting on April 17th. Being local, I wanted to pick up my plants. After calling and calling, I finally got through and Laurel told me that I could come and get them in a week. She also told me that they'd had trouble in the nursery and half of my plants weren't ready, but should be in another week. I decided not to wait and to go and get half the order, planning to return to get the rest a week later. She explained that she was doing the best she could but that I might have to take some substitutions.
I went to pick them up and a very personable woman confirmed that I should come back in a week for the rest.
It is now mid May, and I have been told that the rest of my order can't be filled because I plac... read more

Allium Ursinum is edible -- for humans, other members of the allium family, can be toxic to pets --especially dogs. Allium ursinum is often used when making garlic supplements -- for reducing cholestrol and general cardiac health. It's done quite well here in central VA. though it is, by no means, invasive.

I find this an interesting plant in my woodland garden. It was my mystery plant when I first moved to VT 4 years ago and now I enjoy waiting for the delicate blooms to appear on their red stems.

Vigorous spreading bulb from Most of Europe. Has two broad, bright green strap like leaves. Bears flat topped, umbels of 6-20 white star shaped flowers.

Flowers April to June.

Native of woods and shaded meadows and happily spreads everywhere. The whole plant smells strongly of garlic and can even taint the milk of dairy animals if they eat it. Enjoys a damp, lightly shaded spot without too much competition. They will even tolerate boggy soils.
