Frequently Asked Questions

What hardiness zones is Flame® Pro Purple Garden Phlox suitable for?

  • Flame® Pro Purple Garden Phlox thrives in USDA hardiness zones 3-8. This wide range makes it suitable for most temperate climates across the United States. Plant it confidently in areas with winter lows from -40°F to 20°F.

What is the mature height and width of Flame® Pro Purple Garden Phlox?

  • Flame® Pro Purple Garden Phlox reaches 12-16 inches tall and spreads 15-18 inches wide at maturity. This compact size makes it perfect for front borders and container plantings in zones 3-8. Shop at Nature Hills for this mildew-resistant variety.

What type of soil does Flame® Pro Purple Garden Phlox need?

  • Flame® Pro Purple Garden Phlox thrives in well-draining, fertile soil with consistent moisture. This hardy perennial performs best in slightly acidic to neutral pH (6.0-7.0) and benefits from organic matter worked into the planting area. Ensure good air circulation around plants to maximize the mildew-resistant qualities.

How often should I water Flame® Pro Purple Garden Phlox?

  • Water Flame® Pro Purple Garden Phlox deeply once or twice weekly, providing about 1 inch of water total. This USDA zones 3-8 perennial prefers consistent moisture but well-draining soil to prevent root rot. Water at soil level rather than overhead to protect the mildew-resistant foliage.

When and how should I prune or deadhead Flame® Pro Purple Garden Phlox?

  • Deadhead spent blooms throughout the summer to encourage continuous flowering and prevent self-seeding. Cut stems back to just above the next set of buds or leaves. For fall cleanup in zones 3-8, cut the entire plant back to 2-3 inches after the first hard frost to promote healthy spring growth.

What spacing is recommended between Flame® Pro Purple Garden Phlox plants?

  • Space Flame® Pro Purple Garden Phlox plants 18-24 inches apart on center. Since each plant spreads 15-18 inches wide, this spacing prevents overcrowding while allowing the fragrant purple flower clusters to create a full display. Plant closer for quicker coverage or wider apart in mixed perennial beds.

What are the sun exposure requirements for best blooming?

  • Garden phlox thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal blooming. Partial sun locations will produce fewer flower clusters and may increase susceptibility to powdery mildew. Plant in your sunniest garden spots for the most abundant purple blooms.
