‘Sweet Princess’ is an open-pollinated, disease-resistant heirloom watermelon bearing oblong fruits that reach 20-30 pounds.

Fruits have thin but tough rinds that are light green with dark green marbling. Flesh is pink, crisp, and sweet, with a fine texture and very small tan seeds.

These pink-fleshed picnic watermelons grow to 15 inches long by eight inches wide.

‘Sweet Princess’ has good resistance to fusarium wilt and anthracnose, and will be ready to harvest in 85-95 days.
