Developed for southern growing conditions, this onion thrives in warm climates and produces globe-shaped, golden-yellow bulbs with a mild, sweet taste. Its high sugar content makes it perfect for fresh salads, caramelizing, grilling, and adding to dishes raw or cooked. Texas Supersweet onions are day-neutral to short-day onions, meaning they require 10-12 hours of sunlight to form bulbs, making them ideal for southern states and warm regions.
