Winter melon
Benincasa hispida
Overview
A massive Asian gourd that can grow over 50 pounds, winter melon has a very mild, almost neutral flavor that absorbs surrounding flavors beautifully in soups and braises. Despite the name, it is a warm-season crop harvested in fall and stored through winter — its thick, waxy rind allows storage for months. It is a staple in Chinese, Vietnamese, and Indian cuisines.
Growing Conditions
How to Grow Winter melon
Winter melon (Benincasa hispida) is a vine that grows to about 1.5 feet tall and 13 feet wide.
To grow winter melon, give it full sun. It is hardy across USDA hardiness zones 8–11. Plant it in rich, well-drained, warm soil with plenty of organic matter, at a slightly acidic pH of 6–7. It does best with even, moderate watering.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Its flowers appear from May through August, offering high value to pollinators. Give it a season to establish, and it carries itself through the dry stretches.
Companion Planting & Soil
Winter melon grows well alongside corn, bean, and sunflower — but keep it clear of potato.

Uses
In the Kitchen
In the kitchen, winter melon turns up in more than one form: braised in Chinese soups and stews; made into winter melon tea (a sweet Southeast Asian drink); candied as a confection in Chinese cuisine.
Medicinal & Folk Use
In herbal and folk tradition, it has been valued in several ways: diuretic properties support kidney and urinary health; low-calorie, high-water-content vegetable for weight management; traditional use in Chinese medicine for reducing internal heat. These are traditional uses, not medical advice.
Beyond the Garden
Winter melon earns its keep past the plate, too: stores for months due to thick, waxy rind.
