From late May through mid-June, we have noticed a succession of native shrubs blooming in north-central Minnesota. Each of them has similar small white flowers, and seemingly take turns blooming one after another. Serviceberry was first, in late May. It was followed by Red-osier Dogwood, then Viburnum in mid-June.


Red-osier dogwood


Two species of viburnum are growing close to each other in the woods lining our yard. Their flowers seem nearly identical. The leaves of the Downy Arrow-wood are smaller and have coarsely jagged edges, while the leaves of the Nannyberry are larger with finely toothed edges. Leaves of Nannyberry also have a shinier waxy surface.
