Genus guide
Phlox — 30 species
Part of the Phlox & Jacob’s ladder family (Polemoniaceae)
Phlox is a diverse North American genus ranging from low creeping mats like Creeping Phlox (Phlox subulata) and Woodland Phlox (P. divaricata) to tall border perennials like Garden Phlox (P. paniculata). Most species thrive in full sun with at least six hours of direct light daily, though woodland types prefer dappled shade. Water needs vary: Garden Phlox requires consistent moisture throughout the season, while Creeping Phlox becomes drought-tolerant once established. Toxicity varies across the genus — check each species before buying if you have pets.
