The Texas 1015 onion is a famous sweet onion variety that was first developed by Texas A&M University in the 1980s, and it remains one of the best choices for gardeners in warm regions like South Florida. The name “1015” comes from its ideal planting date, October 15th, but don’t worry, you can plant them in South Florida through the end of the year. These are a “short day” onion, which means you plant them in fall when the days are shortening, and you harvest in spring, as the days start to lengthen. These onions are known for their large, round bulbs, mild flavor, and high sugar content, making them excellent for fresh eating, grilling, and caramelizing.

Unlike pungent storage onions, 1015s are best enjoyed soon after harvest, as their high water content means they don’t keep as long. To grow them successfully here, start with transplants rather than seed, planting in the fall so they can establish through the cooler months. They prefer full sun, loose and well-drained soil, and benefit from plenty of organic matter. Consistent watering is important during bulb formation, but the soil should never stay soggy or the roots will rot. By late spring, you’ll have big, sweet onions ready to pull, but you can also enjoy them anytime along their growth cycle wether small or large. Texas 1015 onions are sometimes called the “million-dollar onion” because of their popularity and the boost they gave to Texas agriculture.
