Noteworthy Characteristics

Phlox is a genus of about 70 species mostly native to North America that are grown for their showy flowers.

The genus name is derived from the Greek word phlox meaning flame in reference to the intense flower colors of some varieties.

‘Green Spring’ is a spreading, mat-forming phlox that is reportedly a cross between P. divaricata and P. amoena. Creeping, leafy stems typically form a foliage mat to 6” tall. Loose clusters (cymes) of fragrant, tubular, lavender-pink flowers with five, flat, petal-like, rounded lobes appear on stems rising slightly above the foliage mat in early spring. Oblong to oval bright green leaves.


No known serious problems exist for this new phlox introduction. For areas where powdery mildew is a problem, consider cutting back foliage after bloom. Spider mites can also be a problem, particularly in hot, dry conditions.


Ground cover, open woodland/shade gardens or naturalized areas. Also appropriate for sunny or lightly shaded areas of border fronts and rock gardens.
