Short - Red Torpedo (Tropeana Lunga) is best suited to fresh bulbs, pickling, grilling, and climate-matched onion production. Its defining kitchen character is mild to pungent depending on cultivar and maturity. Bulb onions respond to day length, latitude, temperature, and planting date.
About Red Torpedo (Tropeana Lunga)
Red Torpedo (Tropeana Lunga) is a biennial selection of bulb onion, with a clumping/tufted habit and an expected height or spread of 13–18 in. It is best suited to fresh allium flavor, kitchen gardens, succession planting, and seed saving. Notable traits include red coloring; harvest leaves, shafts, or bulbs at the stage named on the product page; savory allium flavor ranging from mild green leaves to mature bulbs.
The value of Red Torpedo (Tropeana Lunga) is in the combination of its named traits, clumping/tufted growth, and fit for fresh allium flavor, kitchen gardens, succession planting, and seed saving.
History and provenance
Allium crops have been selected across Eurasia for leaves, shafts, bulbs, storage, color, and response to day length. A cultivar name does not override day-length adaptation, and bunching onions, bulb onions, leeks, and chives should not be treated as interchangeable species. Bulb onions respond to day length, latitude, temperature, and planting date. Variety names alone cannot overcome a mismatch between onion day-length class and the gardener’s region. Short-day onions begin bulbing under shorter day lengths and are best matched to lower-latitude production systems.

Soaking: None required. Stratification: None required. Scarification: None required.
Planting and care
Plant during spring/Fall and provide full sun. Space plants 4 in apart with 12 in between rows. Use loamy with a pH near 6.0–6.5, and follow a moderate watering plan. Support requirement: No-Support. Frost response: Semi-Hardy. Good container fit with drainage, even moisture, and the listed spacing
Harvest and use
Approximately 100-109 Days, from transplanting to market-size bulbs under the proper day length. Weather, soil temperature, and planting method can shift the actual harvest date. Harvest: Harvest leaves, shafts, or bulbs at the stage named on the product page. Uses: Fresh allium flavor, kitchen gardens, succession planting, and seed saving. Flavor: savory allium flavor ranging from mild green leaves to mature bulbs. Seed saving: Insect-pollinated Allium. Best uses include fresh allium flavor, kitchen gardens, succession planting, and seed saving. Flavor and eating quality: savory allium flavor ranging from mild green leaves to mature bulbs.
Saving seed
Select several healthy, true-to-type Red Torpedo (Tropeana Lunga) plants that match the expected clumping/tufted habit and overall plant form. Avoid saving seed only from the earliest or largest individual unless that is your deliberate selection goal. Pollination system: Insect-pollinated Allium. Compatible cultivars of the same species can cross while flowering. Separate compatible varieties that may flower together, or use cages, barriers, hand pollination, or another documented control appropriate to the crop. Red Torpedo (Tropeana Lunga) is a biennial. Seed production may require overwintering, vernalization, or more than one growing season, depending on climate and crop biology. Clean the seed carefully, dry it thoroughly away from direct heat, label the lot with variety and year, and store it cool, dark, and dry. Test germination before an important planting or distribution season.
Common problems
Common concerns: Damping-off, aphids, slugs, caterpillars, leaf spots, root rots, and stress-related bolting or poor establishment. Management: Start with clean seed and mix, match temperature to the crop, avoid overwatering, provide airflow, scout regularly, and rotate families. Diagnosis note: Similar symptoms can have different causes. Compare plants of the same age, record weather and irrigation, and use local Extension or diagnostic support before applying a control.
