An exquisitely coloured red onion with a sweetness that rises above the natural onion pungency suitable for raw and cooked cuisine. Bulbs are very large 'grano' or high top shape with high flattened shoulders - perfect for slicing. Best red storage onion in our 2020-2021 trial - storing 6 months into early Spring. Great cooking onion!

Seed Raising, Growing and Harvest Information
| Plant Type | Site | Spacing | Height | Sowing Depth |
Days to Germination |
Days to Maturity |
|---|---|---|---|---|---|---|
| Hardy Annual |
Full Sun | 3 seed per cell, transplanted 20cm apart or 1 bulb every 4-5cm |
50cm | 6-10mm | 5-12 days @ 17-27 degrees |
100 days |
DIRECT SOW - Plant seed 6-10mm deep, 3-5 seeds every 10cm in rows 40cm apart during July, August or early September in prepared, well-draining soil. Thin to 4-5cm apart or sow 3-4 seeds every 20 cm .
TRANSPLANT - Days to maturity are from direct seeding, subtract 1-2 weeks if transplanting. Start transplants 10-12 weeks before planting date. Sow thickly in flats or 3-4 seeds in 1.5” soil blocks or cells. We have had good even bulb results transplanting 3onions per hole, every 20cm in rows 25cm apart (3 per 60cm bed top)
NOTES - Onions compete poorly with weeds. Cultivate regularly to control weed pressure.
HARVEST - For fresh eating, onions can be harvested whenever they reach desired size. Storage onions can be harvested when 80% of the tops dry up and flop over. Pull bulbs from ground and cure in an airy, shaded place for two weeks at 22-25°F and 80% relative humidity.
STORAGE - Cool slowly, and store at steady temperatures. Rapid cooling followed by a sudden warm period might break dormancy and cause onions to sprout. Optimal storage is at near freezing temperatures at 65-70% relative humidity.
