Description

The wild blue phlox will produce loose clusters of whitish to lavender, fragrant flowers, atop a delicate green mat of leaves. This is a low growing phlox, rarely reaching 18 inches tall.

Cultivation

Phlox divaricata is an ideal flowering ground cover for shade. It will tolerate more sun in cooler areas. Very easy to grow in a variety of soils, it will slowly colonize as its branching stems make contact with the ground and begin to root. A good layer of mulch is recommended in hotter climates to keep the roots cool and moist. A spring bloomer, any time from March to June depending on its geographic location. Zones 4-8

Propagation

Propagate from seed, root division, or layering in late spring.

Additional Notes

Great for rock gardens and borders, Phlox divaricata combines beautifully with early spring bulbs. Just as for other phlox species, it is susceptible to powdery mildew and should be planted where it will get good air circulation.
