May: Columbine

May's plant of the month is one of my favorites: columbine. Columbine thrives on woodland edges between full sun and part shade. The delicate, intriguing flowers nod gently on slender stalks from mid to late spring. The foliage is light and airy, and helps create a calm atmosphere even after the flowers are gone. Later in the season, the seedpods ripen and produce a gentle rattling sound when the wind blows.

The common name columbine actually refers to more than one species. Here, we are usually talking about our native Eastern Red Columbine (pictured at the top of the page), the European Columbine, or hybrids and varieties of either one. The picture above gives an idea of the kind of diversity available in columbine flowers. For simplicity's sake, I'll continue referring to them all as columbine, and the plant information below will be general to all common columbine you would find around here.
