Family

Polemoniaceae

Botanical Name

PHLOX 'Chattahoochee'

Plant Common Name

Chattahoochee Phlox, Hybrid Phlox

General Description

Notable for its tolerance of shade and heavy flowering habit, ‘Chattahoochee’ displays an abundance of dainty, lavender flowers on low, spreading plants from mid-spring to early summer. It is believed to be a naturally-occurring cross between the species Phlox divaricata subsp. laphamii and Phlox pilosa, both native to the eastern United States.

The purple-tinted stems of this perennial hold opposite pairs of short, slender, lance-shaped leaves which may also bear hints of purple as they emerge. Many loose clusters of fragrant, five-petaled, pale lavender flowers appear in mid-spring, continuing well into the summer. The blossoms feature tiny, violet-red centers, and are highly attractive to butterflies.

Grow this phlox in part sun to part shade and fertile, humus-rich, moist but well-drained soil. It is somewhat tolerant of the dry shade conditions found under large trees. After blooming, the faded flower stems may be cut back to maintain a tidy appearance. Use ‘Chattahoochee’ in the woodland garden, shaded mixed border, or as a groundcover beneath larger deciduous shrubs. It is a lovely companion to spring bulbs, wildflowers and ferns.
