Phlox Drummondii Popstars Mix

Phlox Drummondii Popstars Mix Seeds

Phlox drummondii Popstars Mix is an F1 hybrid from Floranova, one of the most talked-about and commercially successful annual phlox series in the modern horticultural industry. The series revolutionized annual phlox breeding by combining a naturally dwarf, strongly branching plant habit with F1 hybrid vigor and a genuinely distinctive flower form that sets it apart from all other annual phlox on the market.

The defining characteristic of Popstars is the flower itself. Each bloom is a small, intricate, star-shaped flower with serrated petal edges and a marbled, two-tone color pattern that gives every flower a shimmering, jewel-like quality. The mix includes bold solids and striking bicolors spanning red, pink, white, deep blue-violet, coral, and purple, creating a combined display that covers the entire mounded plant so completely that the foliage is barely visible beneath the flower mass.

Plants are self-cleaning, meaning faded blooms are replaced by fresh new buds automatically without any intervention from the gardener. This eliminates the need for deadheading entirely and is one of the series’ most practical and commercially valued traits. Improved garden performance and elevated heat tolerance keep a profusion of flowers blooming longer into the season than regular phlox Flowers, making Popstars significantly more resilient in warmer conditions than older annual phlox varieties. The robust root system and strong F1 branching ensure consistent performance from the retail bench through the full growing season.

Plant Information

• Height: 25–30 cm
• Spread: 35–40 cm
• Plant type: Annual
• Hybrid type: F1
• Flowering: First year, continuous throughout the season
• Sun: Full sun
• Soil: Fertile, well-drained soil, pH 6.1–7.3
• Water: Moderate — allow to dry slightly between waterings once established
• Spacing: 20–25 cm apart

Seed Germination

• Seed depth: Cover with 3–5 mm of compost or vermiculite
• Germination time: 3–7 days
• Ideal germination temperature: 20–22°C
• Important: Phlox drummondii requires complete darkness to germinate.
• After sowing, cover seeds well and ensure no light reaches the germination medium.
• Check trays daily and move immediately to a bright, well-lit position as soon as the first seedlings emerge.

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, saturated moisture at 20–22°C and check daily. Move to bright light immediately upon germination.
  Once seedlings develop their first true leaves, transplant carefully into individual pots as Phlox dislikes root disturbance.
• Grow on in full light at cool temperatures.
• Space plants 20–25 cm apart in a sunny, fertile, well-drained position.
• The multi-branching F1 habit means pinching is not essential, though a single pinch at 8 cm height can further increase branching density.
• Good air circulation between plants is important to prevent powdery mildew.
• Water at the base of plants in the morning and avoid wetting foliage.
• Feed every two weeks with a balanced flowering fertilizer throughout the blooming season.
• As Popstars is self-cleaning, no deadheading is required — simply allow spent blooms to drop naturally and fresh buds will follow continuously.
• Light shearing of the plant can encourage a fresh flush of growth and flowering if blooming slows mid-season.
