Spreading Phlox ( Phlox diffusa ) is a perennial shrub with small needle like leaves. This is a small white flowering plant prefers alpine, sub-alpine environments and rocky or sandy soil. This is a low growing plant which is commonly only two to eight inches tall which probably offers survival advantages when confronted with the harsh landscapes of sub-alpine and alpine environments, in which it thrives.
Spreading Phlox is commonly found and adapted high in the mountains and distributed throughout in the western United States and Canada. This plant employs a tap route, which is ideally suited to capture water deeper under ground and also offers an anchor to help the plant cling to the mountain in high wind conditions. The plant is short, and when in full bloom, the flowers may completely obscure the green needle like leaves from view.
The five petaled flowers range in color from a clean, magnificent white to calming understated lavender or pink color.
The blooms are typically visible from May to August and a welcome sight to those who hike at elevation.
