1. Sugar Baby The comparatively small (nine to 13 pounds) sugar baby is often referred to as an icebox watermelon. Developed in 1955, it has soft, sweet fruit and a dark green rind.

2. Sangria Developed in 1985, this supersize variety is beloved for its scarlet-colored, nonfibrous flesh. The melon's popularity has diminished recently owing to a demand for smaller varieties.

3. Golden Midget The rind of the stunning golden midget, a mini weighing only three pounds, turns yellow when ripe. Elwyn Meader and Albert Yeager, well-known breeders at the University of New Hampshire, developed the variety in 1959.

4. Starlight The pristine, amaranth-colored fruit of this mini cultivar glistens with juice. It's easily transportable—and deeply satisfying.

5. Jubilee Developed in 1963, this popular, supersweet cultivar may weigh up to 45 pounds, so it ranks as a giant, a classification conferred on watermelons exceeding 32 pounds at full ripeness.

6. Starbrite The bright pink, medium-firm flesh of this variety, a descendant of the charleston gray and the crimson sweet, is perfect for pureeing into granitas or sorbets.

7. Extazy The pint-size extazy is a seedless melon that averages five pounds and is grown mostly in California and Arizona.

9. Mickylee A lovely, speckled rind and dense red flesh characterize this 22-year-old seedless variety, which averages 12 pounds.

10. Yellow Baby This hybrid is similar to yellow doll in its rind pattern and the color of its flesh; try the tender fruit in a salsa made with jalapeño and tomatillo.

11. Yellow Doll Weighing no more than eight pounds, this extra-sweet, golden-fleshed mini has especially soft fruit, which makes it an excellent ingredient for smoothies and iced cocktails.

12. Little Baby Flower This petite, pink-fleshed cultivar ripens quickly and never exceeds four pounds.

13. Crimson Sweet The amply proportioned crimson sweet is famous for its sugary, bright red flesh; it is a cross of the charleston gray, miles, and peacock varieties and has a honeyed taste that pleasantly offsets feta and mint.

14. Pixie This miniature, seedless melon averages only six pounds and has thick stripes along its rind; the succulent pixie is part of a breeding trend that favors very sweet, seedless fruit.

15. Summer Flavor Numerous subcultivars of this popular variety now exist. Summer flavor #420 is a cross between a crimson sweet and an allsweet.

18. Cream of Saskatchewan This rare, creamy-fleshed melon usually weighs about ten pounds. The cultivar is said to have been brought to North America by Russian immigrants who settled in the Canadian province of Saskatchewan.
