Just finished reading my March/April 2010 Gardening How-To Magazine and there is an article on how to attract bees and butterflies! Bees are something I have been striving to attract and they seem to love my thyme and this other plant.....forget the name! I love watching them go from flower to flower. Turns out that thyme is one of the plants that bees love according to this list!
I'm not sure how I am going to feel about attracting butterflies so they will lay eggs on plants to feed the caterpillars though. I am not familiar with what are good and bad caterpillars. I would hate to accidentally kill the good ones!
