Columbine

Native summer wild flowers for a shady area.

Once the tree canopy is in leaf and only dappled sunlight reaches the soil, a group of summer flowering wild flowers will brighten the shade. As all but one are perennials, once established, these Minnesota natives will please without much annual exertion and provide a pleasing color contrast to the greens and browns of summer shade.

This selection of plants begins with those that transition from late spring into early summer, followed by those that withhold their bloom until after mid-July. They will obtain their moisture requirements from rainfall, but in extreme heat or drought, a helpful soaking will tide them over. These are taller than the spring selection so place the tallest with careful selection.

None require special soil - just a top soil that has medium or moderate richness and good drainage. If the subsoil is clay - no matter. The shade must not be dense as in a deep forest but more dappled or at least with some slanting sunlight for an hour or two.

Now - to get started: Some will start easily from seed but buying bare root young plants from a native nursery is a sure way to get started, after that they reward you with more plants from self seeding and clump enlargement.

Here is a quick look at each of the recommended species - not an exclusive list, but reliably rewarding. Use the link to our web pages for more detailed information, plus more photos. The list follows the sequence of bloom time, from early to latest.


Wild Columbine. (Aquilegia canadensis). Late May into early July, stems 1 to 3 feet high, red flowers with yellow, interesting seed pods. Self-seeds and transplants easily.

Aniseroot. (Osmorhiza longistylis). Late spring to early summer, bushy clump to 24 inches high, umbels of white flowers. Aromatic root. Self-seeds and transplants easily.
