Citrullus lanatus

S tier

Citrullus lanatus is the cultivated watermelon—a trailing annual cucurbit grown for large watery fruit with sweet red, yellow, orange, or white flesh inside a thick rind. Wild relatives are more bitter; domesticated types concentrate sugar and reduce bitterness in the edible flesh. Seeded diploids and seedless triploids both belong here commercially. Wedges, cubes, agua fresca, grilled slices, and pickled rind all start from C. lanatus. When recipes say watermelon without a cultivar, this species is meant. Ripeness cues include a creamy ground spot and dried tendril near the stem. China leads production volume; local peak fruit often outflavours long-hauled imports.
