Another week, another threatened frost: such is Spring in a Zone 3 Bug Garden. Oh well, I should stop whinging and just get on with it. The HBG was first envisioned as a home for pollinators, which I suppose we thought of as mainly bees and butterflies. Well, not really, since at one time or another we have both taught pollination ecology, but embryonic bug garden thoughts aren’t necessarily very deep and butterflies, bees, and flowers was the general idea.
So if you just want flowers and happy pollinators, and don’t mind a preponderance of flies, think large, open inflorescences like astilbe, goldenrod, butterfly weed, yarrow, daisies, caraway, lovage, and the like. If, however, you want apples, cherries, saskatoons, currants, beans, peas, tomatoes, peppers and anything else that requires some skilled pollination, then you need bees, and bees need a home as well as food. I suppose it is well past time that I started learning what bumble and digger bees need to make a home.
