Red Long of Florence Onion is a classic Italian heirloom producing long, tapered bulbs with deep red-purple skins and a mild, sweet flavour. The tender flesh is excellent for fresh eating, slicing, grilling, and light cooking, offering a gentler taste than many storage onions. Best grown as a fresh or short-keeping onion, this variety is valued for its beautiful colour, uniform shape, and dependable performance in home gardens.

*Days to Maturity – Ready to harvest in approximately 100–110 days.
*Elongated Red Bulbs – Attractive long onions with rich red-purple skins.
*Mild, Sweet Flavor – Less pungent than storage onions, ideal for fresh use.
*Italian Heirloom Variety – Traditionally grown for fresh markets and kitchen gardens.

For best results, start onion seeds indoors 8–10 weeks before your last frost date, or direct-seed outdoors as soon as the soil can be worked in spring.

Sow seeds ¼ inch (6 mm) deep and keep soil evenly moist until germination, which typically occurs in 7–14 days. Provide bright light and cool conditions to encourage strong, sturdy seedlings.

After the risk of hard frost has passed, transplant or thin seedlings to a sunny location, spacing plants 4–6 inches (10–15 cm) apart in fertile, well-drained soil. Water regularly and keep beds weed-free for best bulb development.
