Phlox Drummondii Beauty Coral Reef

Phlox Drummondii Beauty Coral Reef Seeds

Phlox drummondii Beauty Coral Reef is part of the Beauty series, classified under the Nana Compacta group of annual phlox which produces shorter, more compact and densely branching plants compared to taller cut flower varieties. This variety has received the Award of Garden Merit from the Royal Horticultural Society, recognizing its exceptional and consistent garden performance across a wide range of growing conditions.

The color palette of Coral Reef is what makes this variety immediately distinctive. Rather than the rich, saturated tones found in bold-colored phlox mixes, Coral Reef presents a carefully assembled selection of unique soft pastel hues — cream, pale peach, apricot, coral, warm yellow-orange, and soft white — that together create a warm, sun-kissed, and harmonious display. The individual flowers are five-petaled, star-shaped, and held in dense rounded clusters atop each branching stem. Many carry a slightly contrasting eye at the center, adding quiet depth to the overall appearance. The blooms carry the characteristic sweet fragrance of annual phlox, described as similar to honey and fresh flowers, making this variety particularly pleasant near seating areas and along garden paths.

Plants grow in a compact, bushy, mounded habit, densely covered in blooms from early in the season and continuing for an extended period with regular deadheading. The Beauty series is well suited to front-of-border planting, container displays, and mass bedding arrangements where the full impact of the pastel palette can be appreciated.

• Important: Phlox drummondii requires complete darkness to germinate. After sowing, ensure all light is excluded from the germination tray or pot. Check daily and move immediately to a bright, well-lit area as soon as the first seedlings emerge to prevent stretching.

Growing Tips

• Sow indoors 6–8 weeks before intended transplanting date.
• Cover seeds with 3–5 mm of sieved compost or vermiculite ensuring complete darkness during germination.
• Maintain even moisture at 15–20°C and check trays daily, moving to bright light as soon as germination occurs.
• Transplant carefully into individual small pots when the first true leaves develop, as Phlox dislikes root disturbance.
• Pinch out growing tips when plants reach 8 cm height to encourage the compact, bushy branching habit characteristic of the Beauty series.
• Grow on at cool temperatures before planting out, spacing plants 20–25 cm apart in a sunny, fertile, well-drained position.
• Closer spacing between plants helps support stems in open positions.
• Good air circulation is important throughout the season to prevent powdery mildew.
• Water at the base of plants in the mornings and avoid wetting foliage.
• Feed every two weeks with a balanced flowering fertilizer.
• Deadhead consistently by removing spent flower clusters to maintain continuous blooming throughout the cool season.
• Taller stems may benefit from light support in exposed positions.
