Check Price on Amazon

The Southport White Globe onion is a classic long-day variety known for producing large, globe-shaped bulbs with a mild to moderately pungent flavor. The 100-count seed pack from Country Creek Acres is presented as a non-GMO heirloom option, well-suited for gardeners seeking reliable germination and classic flavor. This seed pack supports both bulb production in northern zones and bunching options in warmer southern climates, depending on planting timing and spacing.

Gardeners should direct sow in spring for a quick green onion harvest or plant for bulb formation as days lengthen. The variety’s adaptability makes it a practical choice for mixed herb and vegetable beds. For best results, keep soil well-drained, consistently moist, and plan for a long growing season to maximize bulb size and yield.

This batch provides 400 seeds for the long-day Southport White Globe variety. It supports both bunching and bulb formation, depending on climate zones. The seed notes advise direct sowing in spring and again in August for a fall crop. The onion is described as cold-hardy with a slow bolt tendency, making it a dependable choice for gardeners in both cooler and some mild-winter regions. Plant depth, spacing, and row distance vary by regional climate, with specific guidance for southern versus northern growing zones.

Key cultivation takeaways include shallow sowing (about 1/4 inch) and regular thinning to establish proper spacing. In southern zones, thin to 1 inch and maintain 12–18 inch row spacing. In northern zones, thinner spacing within rows to 1–2 inches and maintain the same row spacing. Regular weed control and consistent moisture support bulb development and flavor retention throughout maturation.

The 50-count seed pack continues the same heirloom Southport White Globe lineage, emphasizing non-GMO status and versatility for both scallion cultivation and globe onion yields. This option suits home gardeners with medium-sized plots who want steady access to reliable seed stock without bulk ordering. Planting strategies mirror the 100-count pack, focusing on soil prep, spacing, and seasonal timing to optimize harvest windows and bulb development.

For best results, align sowing with local frost dates and maintain consistent moisture. As with other Southport varieties, providing a long-day photoperiod will encourage bulb formation in suitable climates, while cool-season growth supports robust scallion outputs in early stages.

The smallest listed option offers 25 seeds, suitable for trial plots or gardeners testing germination rates before expanding their seed stock. While volume is reduced, the seeds belong to the same Southport White Globe heirloom family, enabling either quick scallion harvests or gradual bulb development across growing seasons. Depending on geography, planting may follow spring direct sowing or late summer sowing for a fall harvest window.

Careful planning remains essential: provide well-drained soil, consistent moisture, and appropriate spacing. Northern climates benefit from longer day exposure to push bulbs, while southern regions may prioritize earlier sowing and staggered harvests for successive crops.

Buying Guide: Southport White Globe Onions

When selecting Southport White Globe seeds, consider climate, intended harvest, and garden space. The variety thrives under long-day conditions, producing globe-shaped bulbs in cooler-than-average nights and longer daylight periods. For home growers, deciding between seed counts depends on plot size, seed germination rates, and whether you want immediate scallions or bulbs.

  • Climate suitability: Northern regions favor bulb formation; southern regions may focus on scallion production and fall crops with appropriate timing.
  • Seed quality: Non-GMO and heirloom designations reflect traditional breeding goals and storability; check seller notes for germination guidance.
  • Spacing and depth: Most sources recommend shallow sowing (about 1/4 inch) and row spacing of 12–18 inches; thinning is essential to prevent overcrowding.
  • Planting timing: Direct sow in spring, with an August option for a fall harvest in suitable climates. Cold-hardiness can extend growing windows in milder winters.
  • Harvest planning: For bulbs, monitor for bulb size and neck firmness; for scallions, harvest when stalks reach the desired length without stressing the plant.

Comparative considerations across product options include seed count, seller trust, and packaging convenience. Gardeners with limited space may start with a 25 or 50-count pack to gauge germination and performance before investing in larger packs. Always ensure seed packets are clearly labeled as Southport White Globe and non-GMO when that designation matters to your gardening goals.
