## Description

Seed Needs Onion Seeds for Planting White Sweet Spanish Long Day Onions - Non-GMO Heirloom & Untreated Vegetable Seeds to Plant an Outdoor Home Grown Veggie Garden (1 Pack)

## Features

- Growth Cycle: Long Day Yellow Sweet Spanish onions require long daylight hours for bulb formation, typically needing 14-16 hours of daylight. They are best suited for regions in the higher latitudes, like the northern U.S. and Canada.
- Flavor Profile: These onions are known for their sweet, mild flavor compared to other onion varieties. They have a high sugar content which contributes to their sweetness, making them excellent for caramelizing or eating raw in salads.
- Size and Appearance: They grow quite large, often reaching sizes that can exceed 1 pound each. They have a golden-yellow skin with a white or slightly yellow flesh inside. The bulbs are globe-shaped with a firm texture.
- Storage: While they are sweet and thus less pungent than storage onions, they don't store as long. They can last for a few months if kept in a cool, dark, well-ventilated place, but they are generally recommended for consumption relatively soon after harvest.
- Quality: All Onion seeds packaged by Seed Needs are intended for the current and the following growing seasons. All seeds are stored in a temperature controlled facility that is free of significant amounts of moisture.
- Quantity: Seed Needs offers generous quantities. You can share with friends and family, or you can save the extra seeds until the following season, if properly stored.
- Packets: Each seed packet displays an artful illustration of the variety to be grown, as well as detailed seed sowing information on the reverse side. They measure 3.5" wide by 5" tall.
- Promise: Seed Needs will never knowingly supply GMO based seed products. The vast majority of our seeds are open pollinated & heirloom, with the exception of a few hybrids.
- Germination: Seed Needs packets contain some of the freshest seed available. Direct from the growers. If sown correctly, you will begin seeing results in only a matter of days.
- Freshness: All seeds are packaged in tear resistant and moisture resistant packaging. This keeps the seeds a whole lot fresher than the competitions selection!
