Blue Moon Garden Phlox – Fragrant Woodland Native Charm
We're bringing you the moon! The Blue Moon Garden Phlox (Phlox divaricata 'Blue Moon'), also known as Woodland Phlox, is a native woodland wildflower beloved for its dense clusters of soft violet-blue, lightly fragrant blooms! This perennial is spring-blooming, pollinator-friendly, and thrives in dappled light!
It's compact and low-growing, perfect for tucking into shady borders, under deciduous trees, or naturalized woodland settings. In early to mid-spring, the plant bursts into bloom with clusters of starry, five-petaled flowers that range from lavender to powder blue. Pollinators flock to it, especially early-emerging butterflies and native bees!
Forming a lush, low mound, Phlox divaricata spreads politely by creeping rhizomes (underground stems), making it a slow but steady groundcover. Its semi-evergreen foliage is lanceolate, long and pointed, held on wiry, branching stems that rarely grow taller than 6-12 inches and spread about 1-2 feet wide. The leaves may stay green through a mild winter, giving this Phlox an early jumpstart come spring!
Culturally symbolic of harmony, sweet dreams, and resilience, Phlox divaricata and its cultivars like 'Blue Moon' remind us how nature layers texture, scent, and charm into the shade garden.
