|'Black Spanish' is an heirloom variety of watermelon. The fruits are squat and oblong, with deep ribbing. The rind is blackish green, and 1.5 inch thick. The flesh is red and sweet.
C. lantatus generally do best in warm climates. Cool weather will not produce good fruits, but some of the adversity of cool weather can be overcome by starting seeds early indoors, and transplanting them out at the height of summer. Plastic groundcovers are highly recommended to increase soil temperature in the spring, and rowcovers will help the crop ripen in the fall.
