Interesting Facts


Phlox are a beautiful family of plants that no garden should be without. Tall garden and meadow phlox produce large panicles of fragrant flowers in a wide assortment of colors adding height and charm to any border. Low-growing moss pinks, and creeping phlox are effective as ground covers, at the front of the border, and as rock garden plants, especially in light shade. 




Prefers moist, humus-rich, well-drained soils in full sun. Best flowering is in full sun, but plants generally appreciate some dappled sun in the hot summers of the South. Good soil drainage is important.
