3. Borage (Borago officinalis) This annual herb has bright blue clusters of edible, cucumber-flavored flowers. Studies in Switzerland have shown borage to be exceptionally attractive to good bugs, with an average of over 100 beneficials found in just 1 square yard of borage. In addition, common green lacewings have a very strong preference to lay their eggs on borage. Look for borage on garden center seed racks and mail order seed catalogs.
