Forever Pink phlox is a Chicagoland Grows® selection. Chicagoland Grows® is a plant introduction partnership of the 91½ûÂþ, the Morton Arboretum and the Ornamental Growers Association of Northern Illinois formed to promote plant cultivars that perform well in northern Illinois. This variety was developed at the 91½ûÂþ; its 1-inch-wide, purplish-pink flowers cover the plants for three weeks in June with repeat blooming into October. The plants are dense and clump-forming, and remain upright all season, unlike many of the taller Phlox.
