Rosella 'Early' Seeds

Rosella 'Early' (Hibiscus sabdariffa), a prized heirloom strain selected for its faster maturity and high productivity. Renowned across Australia for producing brilliant ruby-red calyces, this fast-growing tropical and subtropical bush offers a striking display of pale yellow hibiscus flowers with deep maroon centers, followed by heavy clusters of succulent red fruit heads.

Selected to flower and set fruit earlier than standard varieties, 'Early' Rosella is ideal for gardeners in temperate and cool-climate zones with shorter summer windows, as well as classic warm-climate regions. The thick, fleshy calyces boast a sharp, cranberry-like flavor that shines in homemade jams, ruby-red herbal teas, jellies, cordials, and syrups. Rich in Vitamin C and antioxidants, this multi-purpose bush is as ornamental as it is edible.

• Faster Flowering Strain: Specially selected to produce calyces earlier in the season, extending harvests in shorter-summer regions.

• Vibrant Ruby Harvests: Produces thick, fleshy crimson calyces perfect for homestead preserves, teas, and syrups.

• Ornamental & Edible: Features gorgeous cream-and-burgundy flowers set against lush red-veined foliage.

• Nutrient-Dense Superfood: Packed with Vitamin C, antioxidants, and natural tart flavor.

• Multi-Use Homestead Crop: Tender young leaves are also edible as a tangy salad green (known as bush sorrel).

Growing Information (Australia):

• Scientific Name: Hibiscus sabdariffa 'Early'

• Plant Type: Tender Warm-season Annual (Perennial in tropical, frost-free zones)

• Growth Habit: Branching Shrub / Bush (Non-vining; grows into an erect, woody sub-shrub)

• Sowing Season:

  • Temperate/Cool (e.g., Victoria, Tasmania): Early Spring (strictly raise indoors/greenhouse with bottom heat 6–8 weeks before last frost).

  • Subtropical: Spring to Early Summer.

  • Tropical: Late Winter to Spring (at the start of the wet/warm season).

• Sun Position: Full Sun (requires 6–8 hours of uninterrupted direct sunlight daily).

• Sowing Depth: 6mm–10mm deep (Soak seeds in warm water for 12–24 hours prior to sowing to break seed coat dormancy).

• Plant Spacing: 80cm–100cm apart between plants.

• Plant Height: 120cm–150cm tall.

• Germination Temp: 22°C–30°C.

• Germination Time: 10–21 days.

• Seed to Bloom/Harvest Time: 120–140 days (harvest calyces when plump and tender, before they turn woody).

• Gardener’s Tip: Soak seeds overnight in warm water to speed up germination. Plant in free-draining, highly fertile soil enriched with organic matter. Protect young seedlings from frost at all costs. Pick the plump red calyces continuously using sharp snips as soon as the flower petals drop; regular harvesting encourages the plant to set continuous flower buds until autumn.
