All Sweet is an heirloom watermelon, a direct descendant of the Crimson Sweet variety, known for its bright red, juicy flesh with rich sweetness and relatively few seeds. The fruits are large and oblong, typically measuring 17 to 19 inches long and 7 inches across, weighing 25 to 35 pounds on average. The rind is vibrant green with lighter or dark green striping, and the tough outer skin resists bruising, making it suitable for transport. This variety is open-pollinated and has been a favorite among gardeners for generations due to its flavor and dependable performance.
