Spring Onion Cipollotti a Mazzo Seeds Bunching Allium fistulosum by Franchi Seeds

Description

Cipollotti a Mazzo is a heritage bunching onion grown for its long white stems and fresh green tops. No bulb, just mild sweet stems that you pull and eat as scallions. Ready in about 8 to 10 weeks from sowing.

Sow from March to September for a continuous supply. Use them in salads, stir-fries, omelettes, and as a garnish on anything that needs a fresh onion flavour without the sharpness of a full onion.

🌱 Sowing information
Sow February under cover and March–July outdoors in firm, fine soil or deep containers. Draw 1 cm drills spaced 15–20 cm apart and sow thinly. Keep moist during germination. For bunching stems, sow closer so plants grow as a natural “mazzo” (bunch).
☀️ Light exposure
Prefers full sun but tolerates light partial shade. In Ireland, a sunny open bed, tunnel or bright patio spot gives upright growth and clean white stems.
💧 Water needs
Keep soil evenly moist, especially in free draining beds or containers. Regular watering prevents toughness or splitting. Avoid waterlogging to reduce rot risk.
🌡️ Germination temperature & time
Germinates at 10–20 °C, usually in 7–21 days. Early sowings benefit from cloches or greenhouse warmth; later sowings can be made directly outdoors.
📏 Plant spacing & final size
Thin to 2–3 cm for slender single stems, or leave closer for bunching onions. Rows 15–20 cm apart are sufficient. Mature plants reach 20–30 cm tall with long white shafts.
🌼 Harvesting notes
Harvest May–November, pulling single stems or lifting whole bunches at pencil thickness. For extended cropping, snip a few leaves from each clump before lifting full bunches later.
