Faits intéressants

Wild Blue Phlox produces fragrant, pale blue, lavender, or occasionally white flowers in spring. It naturally grows in rich deciduous woods, woodland edges, and shaded slopes. It prefers moist, well-drained soil, although established plants can tolerate somewhat drier conditions. The spreading stems create an attractive groundcover beneath trees and shrubs. It benefits from consistent moisture during establishment. Avoid hot afternoon sun and very dry soil.
