PHLOX

Most phlox are natives of North America. With the exception of P. drummondii (annual phlox), the species described here are perennial. The many types show wide variation in form, but all have showy flower clusters. Tall kinds are excellent border plants; dwarf ones are mainstays of the rock garden. Unless otherwise noted, grow in ordinary garden soil and provide regular moisture. Two major problems affect phlox: red spider mites (attack almost all species) and powdery mildew (P. paniculata is especially susceptible).

Phlox subulata

From eastern the U.S. Forms a mat to 6 in. high and 1 1/2 ft. or wider, with creeping stems clothed in small, needlelike evergreen to semievergreen leaves. Blooms profusely in late spring or early summer, bearing 3/4-in. flowers in white and colors including pale to deep shades of pink, and lavender-blue. Plant in loose, not-too-rich soil; give moderate water. After flowering, cut back halfway. Specialists offer dozens of varieties and hybrids, such as ‘Tamanonagalei’ (‘Candy Stripe’), which has rose-pink blossoms edged in white; it is more drought-tolerant than the average moss pink and has good fall rebloom.
