Phlox subulata


This shade tolerant North American Native is a great species that provides year-round interest on a green roof. Foliage grows in a low mat featuring vibrant, dark green, needle-shaped leaves that resemble the foliage of coniferous evergreens. Foliage generally stays green year round, though can brown out in colder climates through the winter. A beautiful carpet of lavender flowers appears in a burst of color in very early spring. Like most perennials used on green roofs, this plant will benefit from growing in a deeper soil profile or in mounded green roof media. It will need regular water to become established on the roof.

Large quantities may require custom growing. Please contact office for lead times.
