Quick Grow Facts
-
Plant: Hibiscus moscheutos, Luna Mix; an ornamental herbaceous perennial, distinct from tropical hibiscus and edible roselle.
-
Seed form: 5 or 100 raw seeds per pack. Raw does not establish untreated status. Keep and follow packet safety warnings.
-
When to sow: Spring to early summer, with warmth and protection from frost; adjust to your local conditions.
-
Method and depth: Start one seed per tray cell or small pot, covered about 5 mm deep in fine seed compost. Covered germination; give emerged seedlings light.
-
Warmth and germination: Aim for 20–24°C in the medium. The displayed packet gives 14–21 days as a planning window; timing varies.
-
Seed preparation: Ask for packet-specific advice before soaking or nicking. No additional pretreatment is confirmed for this lot.
-
Position and spacing: Full sun; 61–91 cm between garden plants. This replaces the 10 cm garden spacing shown on the displayed label.
-
Mature size: About 61–91 cm tall and 61 cm wide; upright, naturally branching growth without routine pinching.
-
Water and soil: Fertile, moisture-retentive soil; keep roots consistently moist while growing, with drainage for trays and containers.
-
Flowers: Roughly 15–20 cm blooms in summer and late summer. First-year flowering needs sufficient warmth, light and growing time; mix colours are not guaranteed per small pack.
-
Winter: Expect dieback in cool conditions and a slow spring restart. Protect young plants and do not discard a dormant crown too early.
Help young plants settle in
Transplant when true leaves have developed and roots hold the plug together. Harden gradually before planting out after frost risk. Water the root ball thoroughly and leave space for air to move between plants. If seeds fail to emerge or buds drop, check warmth, moisture and pests before applying extra treatments.
Enjoy the flowers safely
Grow this mix for ornamental display. Sowing seed is not for eating, sprouting or animal feed. Do not use Luna Mix as a substitute for roselle in tea or food, and keep seeds away from children and pets.
