HORTICULTURAL
Plant Sale Text: This early-flowering SE native is an excellent garden plant. Its panicles of fragrant pale blue to white flowers are plentiful in the spring and make great cut flowers. Eastern blue phlox is semi- evergreen and makes a fine edging or woodland groundcover. Often found growing in rich woods, this phlox self- sows to create impressive drifts. Try planting in combination with eastern columbine for a beautiful spring garden.

Bloom Table Text: This native North Carolina perennial blooms April through June. It grows to twenty inches tall and produces clusters of purple-blue flowers that are quite fragrant and abundant. Phlox species have been extensively hybridized and are popular among gardeners because they spread very readily, forming a carpet of flowers in early spring. The name for this plant comes from the Greek word for “flame”, which may refer to the torch-like shape of the buds. Eastern blue phlox is also known as wild sweet William.
