#ProPlantTips for Care:

Plant your new Purple FLAME™ Phlox in a sunny location! The colors will glimmer in the sunlight. They tolerate part shade too, so no need to stress about a location. They're known for being strong perennials, and surviving some frosts with proper care! Northerner gardeners can enjoy the vibrant colors of flowers too! As for soil, provide well-drained soil. They will thrive even more in moderately fertile soil. Water this plant regularly because you don't want the sun drying this plant out too much but avoid overhead watering, too.

Provide good air circulation to avoid powdery mildew. This shouldn't be an issue, though, as this kind of Garden Phlox is known for being disease-resistant and has good mildew resistance. Pruning is recommended during late autumn to ensure the next blooming season goes well. We recommend adding a 3-4 inch thick layer of arborist mulch so the roots are kept cool and protected.

Deadhead as soon as the flowers fade to encourage a rebloom and clean up the mounds, it's also a good idea to deadhead to avoid any self-seeding. Prune down the entire plant once frost kills back these herbaceous perennials. Every 3-5 years, it's recommended to divide your clumps to maintain vigor.

  • Best Blooms in Full Sun
  • Moderate Regular Moisture
  • Well-Drained Soil
  • Can Remain Evergreen in Mild Winters
  • Deadhead After Flowering & Prune in Fall
