Ruby Red Onion Seeds

Allium cepa Ruby Red Onion

Allium cepa Ruby Red Onion is a dependable, long-day variety valued for its hard, brilliant deep red bulbs and robust, pungent flavor. Growing to about 12 to 18 inches tall with bulbs reaching 4 to 6 inches in diameter, this variety is a reliable performer in Northern gardens, producing high yields of globe-shaped onions that store exceptionally well. Unlike milder sweet onions, Ruby Red retains its firmness and zest through winter, offering a vibrant pop of color and bite to culinary dishes long after the harvest season ends.

 

Culinary and Practical Uses

• The firm, crisp flesh is perfect for slicing raw onto sandwiches, burgers, and salads, adding both a sharp, zesty crunch and a vibrant purple-red contrast.  
• Excellent for pickling or cooking down into savory jams and chutneys, where the deep color intensifies and the pungent flavor mellows into richness.
• A superb storage onion, keeping sound and flavorful for months in a cool, dry place, ensuring a steady supply of kitchen staples throughout the winter.

 

Characteristics

• Foliage: Upright, tubular, blue-green leaves (scapes) that photosynthesize rapidly to fuel bulb growth; eventually flopping over to signal maturity.
• Growth Habit: Biennial grown as an annual; produces a tight, globe-shaped bulb with deep burgundy skin and thick, white rings edged in red.
• Flowers: While harvested before blooming for bulbs, if left to bolt in the second year, it produces tall stalks topped with spherical lilac-white flower umbels.
• Seeds: Small, angular black seeds; vigorous germinators that are best started indoors early in the season to maximize bulb size.

 

Growing Requirements

• Sun: Thrives in full sun; requires long summer days (14+ hours of daylight) to trigger the bulbing process effectively.
• Soil: Prefers loose, fertile, well-draining soil rich in organic matter; compact or clay soil can deform bulbs.
• Water: Requires consistent moisture, especially during the bulb expansion phase; shallow roots dry out quickly, so regular watering is key.
• Spacing: Plant transplants 4 to 6 inches apart in rows 12 to 18 inches apart to allow for full globe development and airflow.
• Maintenance: Keep beds weed-free to prevent competition; stop watering when tops begin to yellow and fall over to allow the bulbs to cure properly.
