Phlox Drummondii Popstars Red

Phlox Drummondii Popstars Red Seeds

Phlox drummondii Popstars Red is an F1 hybrid from Floranova, part of the Popstars series — one of the most commercially successful and widely recognized annual phlox introductions in modern horticulture. The series is defined by its unique star-shaped flower form with characteristic serrated petal edges, F1 hybrid vigor, naturally compact and mounded habit, and the fully self-cleaning quality that eliminates deadheading entirely throughout the growing season.

Popstars Red delivers one of the most immediately arresting color statements in the series. The vivid, saturated red blooms carry maximum visual impact across all distances in the garden, creating a bold, confident display that commands attention wherever it is planted. Each star-shaped bloom features the series’ signature serrated petal edges and the marbled, layered quality of the Popstars flower form, giving the red a depth and richness that goes beyond a flat, solid hue.

Red is one of the strongest and most commercially reliable colors in the annual bedding plant market, and within the Popstars series it performs with the same vigor and consistency as all other varieties, producing a continuous mass of blooms from first flower through the end of the cool season. The dense, mounded plant is covered so completely in red stars that foliage virtually disappears beneath the flower mass, creating an extraordinary carpet of color.

The robust root system and strong F1 branching ensure consistent, tidy performance from production through the full growing season. Improved heat tolerance over standard annual phlox varieties keeps plants blooming longer and more reliably in the warmer parts of the cool season.

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 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 20–22°C and check daily. Move to bright light immediately upon germination.
• Transplant carefully into individual small pots when the first true leaves develop, as Phlox dislikes root disturbance.
• The multi-branching F1 habit makes pinching optional, though a single pinch at 8 cm height further increases branching density. Grow on in cool, well-lit conditions before planting out.
• Space plants 20–25 cm apart in a sunny, fertile, well-drained position.
• Good air circulation between plants prevents powdery mildew.
• Water at the base of plants in the morning and avoid wetting foliage.
• Feed every two weeks with a balanced flowering fertilizer.
• As Popstars is fully self-cleaning, no deadheading is required at any point in the season.
• A light overall shearing mid-season can encourage a fresh flush of flowering if blooming slows down.
