This classic heirloom icebox type melon was first introduced in 1959 and quickly became popular for its small size and high sugar content. Sugar Baby vines produce small, round watermelons averaging eight to ten pounds each, with a very sweet, crisp, red flesh. The Sugar Baby watermelon ripens in about 75 days, compared to 120 days for full-sized watermelons. This compact variety is an ideal candidate for smaller gardens.
