About Hibiscus coccineus Red Star The Hibiscus coccineus Red Star, commonly known as Scarlet Rose Mallow or Swamp Hibiscus, is a striking hardy perennial native to the southeastern United States. With its large, vivid red star-shaped flowers and tall, upright stems, this plant adds tropical brilliance to gardens, ponds, and wetlands. Known for its resilience and eye-catching blooms, the Red Star Hibiscus thrives in warm, sunny climates and can reach up to 6–8 feet in height, creating a dramatic garden focal point. Its bold red petals attract hummingbirds, bees, and butterflies, making it an essential addition to pollinator-friendly gardens. For best germination and bloom performance, start your garden with premium Hibiscus coccineus Red Star seeds available at Dharaseeds.com trusted for high-quality, rare, and exotic flower varieties. Why Grow Hibiscus coccineus Red Star? Stunning flowers: Large red star-shaped blooms up to 6 inches across. Pollinator magnet: Attracts butterflies, bees, and hummingbirds. Water-tolerant: Ideal for pond edges, rain gardens, or wet soil areas. Hardy perennial: Survives mild frost and returns stronger each year. Low maintenance: Minimal care needed once established. When to Plant Hibiscus coccineus Red Star Best Time: Early spring to early summer, once frost danger has passed. Temperature: Soil should be 70–80°F (21–27°C) for germination. Indoor Sowing: Start 6–8 weeks before the last frost date for an early bloom. Outdoor Sowing: Direct sow after the last frost when soil is consistently warm. Where to Grow Hibiscus coccineus Red Star Sunlight: Requires full sun (6–8 hours daily) for optimal flowering. Soil: Prefers moist, rich, well-draining soil with plenty of organic matter. pH Range: Slightly acidic to neutral (6.0–7.0). Best Locations: Excellent for water gardens, boggy borders, or near ponds and streams. How to Grow Hibiscus coccineus Red Star Seed Preparation Soak seeds in warm water for 24 hours before sowing to soften the outer coat. For faster germination, gently scarify seeds using sandpaper. Planting Sow seeds ¼ inch deep in moist soil. Maintain steady moisture until seedlings emerge (10–20 days). Transplanting When seedlings reach 4–6 inches tall, transplant them outdoors, spacing 2–3 feet apart. Watering Keep the soil consistently moist, especially during flowering. Tolerates wet soil better than drought conditions. Fertilization Feed with a balanced slow-release fertilizer in early spring and mid-summer. Avoid excessive nitrogen to prevent lush foliage with few flowers. How to Care for Hibiscus coccineus Red Star Pruning: Cut back stems to 6 inches above ground level after the first frost. Mulching: Apply organic mulch to retain soil moisture and regulate temperature. Pests: Generally pest-free but watch for aphids and whiteflies. Use neem oil if needed. Winter Protection: In cold zones, apply thick mulch or bring potted plants indoors. Deadheading: Remove spent blooms to encourage continued flowering.
