Heat-tolerant and reliable. Open-pollinated. 80 days.

Why Grow Yellow Gem?

• Bright yellow, crisp, very sweet flesh — a showstopping alternative to red-fleshed watermelons
• Heat-tolerant — thrives in warm summer conditions
• 14–16 lb oval fruits — bold dark-striped rind, medium thickness
• Conversation piece — yellow flesh surprises and delights at the table
• Open-pollinated heirloom — save seed year after year

In the Kitchen

Slice into thick wedges and serve ice-cold for summer snacking — the yellow flesh is visually striking on any table. Cube into fruit salads alongside red watermelon and cantaloupe for a colorful spread. Blend into agua fresca or lemonade. Serve at backyard cookouts and watch the reaction when guests cut into the golden interior. The crisp, very sweet flesh holds up well and has minimal seeds.

Growing Notes

Start indoors 3–4 weeks before last frost, or direct sow after last frost when soil has warmed to at least 70°F. Sow 1 inch deep in rich, well-draining soil (pH 6.0–7.0) in full sun. Space plants 36 inches apart and give vines 6–8 feet to run. Water deeply and consistently — reduce watering as fruits approach maturity to concentrate sweetness. Harvest when the ground spot (belly) turns creamy yellow and the tendril nearest the fruit dries and browns completely.
