September: Anemone

We all want some late season blooms to keep our landscapes vibrant as the temperatures cool off, and anemone is an excellent candidate. Also known as windflower, these perennials send up long stalks with airy white or pink flower in September and October, and they sway gracefully in a breeze for an ethereal feel.

There are many different landscape-friendly species in the anemone genus with many different shapes, sizes, and bloom times (and they’re all called anemone or windflower), but we’ll be focusing on the taller plant sometimes known as Japanese windflower, not the smaller perennials typically classified with bulbs. For most of the year, the dark green grape-leaf-like foliage forms a decent sized mound, and then in late summer into fall the flower show starts. When they find a spot they like, they really take off and can be split to keep them shorter and more tame. They do not always transplant well, but when they do become established they are survivors.
