Along with mums and salvias, Asters are the swan song of late season flowering color in the garden. There is a wide array of flower color and size as well as plant height. Asters are also easy to grow!
Asters belong to one of the largest, most diverse flowering plant families, Asteraceae. They have evolved to utilize insects and wind for extremely efficient pollination and seed dispersal. (Just think of the dandelion!) Asters are native throughout the globe with nearly fifty species native to the Pacific Northwest. In an effort to narrow this vast family, this article will focus on perennial species commonly used in the garden.
Taller varieties are wonderful cut flowers and combine well with ornamental grasses, golden rod (Solidago) and roses that make good hips (such as R. rugosa). Shorter varieties provide mounds of bright color in containers and boarder edging. They combine well with ornamental cabbage and kale, oregano 'Kent Beauty' and low evergreen shrubs such as heather (Erica).
