I would like to encourage bees into my garden. The best plant for this I've been told is vipers bugloss. Is it possible to buy these plant are to I have to find wild ones?
If you don't find the one you're discussing, try Bee Balm (Monarda)... It comes in many varieties and colors, has exceptional fragrance and bees love it. Here's a picture: http://altnature.com/gallery/beebalm.htm
