A Botanical History of Flames and Explorers

Phlox carries a rich linguistic and historical heritage:

• The Meaning of Flame: The generic name phlox is derived directly from the Greek word for “flame,” perfectly describing the vibrant, fiery intensity of its blossoms.
• Honoring a Scottish Botanist: The species name drummondii honors 19th-century Scottish botanist Thomas Drummond, who spent nearly two years collecting unique flora across Texas and the American frontier.
• Victorian Romance: In the Victorian language of flowers, phlox symbolized the union of souls or sweet dreams, and a gifted bouquet often served as a timid proposal of marriage!

Garden Performance and Landscape Uses

• The Versatile Edger: At 14 inches high, it makes an exceptional ground cover, garden border accent, or vibrant pop of color in rock gardens and containers.
• Prolific Bloomer: Pinching back young tips encourages heavy branching, while deadheading spent blooms keeps the brilliant red carpet flowering heavily right through early fall.

Growing and Care Tips

1. Sowing: Direct-sow seeds in late fall just below the surface, or cold-stratify spring-planted seeds in moist sand in the refrigerator for 60 days. Alternatively, start them indoors 6–8 weeks before your last spring frost at an ideal germination temperature of 65 degrees F.
2. Moisture & Maintenance: Water young seedlings until established. While mature plants handle occasional dry spells well, they perform best with regular moisture during dry weather.
3. Seed Saving: Watch for small seed pods to turn brown after flowering. Harvest them just before they pop open to prevent the seeds from scattering in the wind, dry them indoors, and store in a cool, dry place.
