False spirea Sorbaria sorbifolia Photo/Illustration: Jerry Pavia 1 2 3 4 5 6 7 8 9 10 11 False spirea (Sorbaria sorbifolia) sor-BAR-ee-ah sor-bih-FOE-lee-ah Genus: Sorbaria If you like plants that stay in tidy, little assigned corners, this is not the plant for you. But if you have a large space to fill and love plants with attitude, this is your baby. False spireas form large masses of arching branches that are covered with green pinnate leaves. Billowy white sprays of flowers appear in mid- to late summer. Mature plants spread where you let them. There is a wide range of closely related species and selections, but there’s not much difference between them. Noteworthy Characteristics: Can be invasive in some areas. Care: These plants are unbelievably durable and will take just about any soil thrown in their general direction. An annual or occasional decapitation to the ground is a good idea because it helps keep the plant under control. Propagation: By cuttings or seed. Problems: No serious problems.
