Watermelons are perhaps the most iconic summer fruit, but many other melons offer similar refreshing qualities. The Cucurbitaceae family includes numerous melon varieties beyond the familiar watermelon. Canary melons, with their bright yellow rinds and sweet-tangy flavor, provide a unique alternative to traditional watermelon.

Some lesser-known melons closely resemble watermelons in appearance or taste. The Belmont watermelon, for instance, shares the oblong shape and striped green rind of common watermelon varieties. However, it tends to be larger, often weighing between 20-30 pounds. Galia melons offer another intriguing option, combining a spicy-sweet flavor with a juicy, succulent texture reminiscent of watermelon.

History and Classification

Watermelons have a rich history dating back thousands of years. They belong to a diverse family of plants that includes various melon types and other related fruits.

Watermelon Origins

Watermelons (Citrullus lanatus) originated in southern Africa over 5,000 years ago. Ancient Egyptians cultivated watermelons and depicted them in hieroglyphics. The fruit spread to other parts of Africa and the Mediterranean region.

By the 10th century, watermelons reached China. They were introduced to Europe in the 13th century and arrived in the Americas with European colonists in the 16th century.

Early watermelons were likely smaller and less sweet than modern varieties. Selective breeding has led to the development of numerous cultivars with varying sizes, colors, and flavors.

Melon Family Overview

Watermelons belong to the Cucurbitaceae family, also known as gourds or cucurbits. This family includes:

• Cucumis genus: Cucumbers, cantaloupe, honeydew
• Citrullus genus: Watermelon, citron melon
• Other related fruits: Bitter melon, horned melon (kiwano)

Cucurbitaceae plants typically have trailing vines and produce large fruits. The family includes both edible and ornamental species.

Some unique members of this family are:

• Cucamelon: Tiny melon resembling miniature watermelons
• African horned cucumber: Spiky fruit with jelly-like interior
• Bitter melon: Warty green fruit used in Asian cuisine

Moon and Stars is a striking heirloom variety, easily recognized by its dark green skin decorated with yellow spots resembling celestial bodies. Its red or pink flesh offers a sweet, traditional watermelon flavor.

Seedless varieties, like Trio and Summer Sweet, have gained popularity for their convenience. These hybrids produce sterile seeds, resulting in fruit with few or no hard seeds.

Golden Midget is a unique cultivar that produces small, 3-5 pound melons with golden-yellow rinds when ripe. Its pink flesh provides a surprising contrast to its exterior.

Orangeglo, an heirloom type, stands out with its vibrant orange flesh. This variety offers a distinct, almost tropical flavor profile that differs from traditional red watermelons.

Nutritional Profile

Watermelon-like fruits offer a range of essential nutrients while being low in calories. These refreshing fruits are packed with vitamins, minerals, and antioxidants that contribute to overall health and well-being.

Vitamin and Mineral Content

Watermelon and similar fruits are excellent sources of vitamin C, providing a significant portion of the daily recommended intake. They also contain vitamin A, which supports eye health and immune function.

Potassium is another key mineral found in these fruits. It plays a crucial role in maintaining proper heart and muscle function. Many watermelon-like fruits are also rich in lycopene, a powerful antioxidant that gives them their characteristic red or pink color.

These fruits typically have a high water content, often around 90% of their total weight. This makes them ideal for hydration, especially during hot weather or after physical activity.

Health Benefits

The nutritional profile of watermelon-like fruits contributes to various health benefits. Their high vitamin C content supports the immune system and helps protect cells from damage.

The antioxidants present in these fruits, particularly lycopene, may help reduce the risk of certain chronic diseases. Some studies suggest that lycopene consumption is associated with a lower risk of heart disease and some types of cancer.

These fruits are naturally low in calories, making them a good choice for weight management. They also provide a small amount of fiber, which aids in digestion and promotes feelings of fullness.

The high water content in these fruits supports hydration and may help improve skin health. Additionally, the potassium found in watermelon-like fruits can contribute to maintaining healthy blood pressure levels.

Other Melon Types

Melons come in a diverse array of varieties beyond the common watermelon. These fruits offer unique flavors, textures, and appearances to suit different tastes and culinary applications.

Culinary Uses

Watermelon’s versatility shines in both sweet and savory dishes, as well as refreshing beverages. Its juicy flesh and seeds offer a range of culinary possibilities, perfect for summer enjoyment.

Sweet and Savory Recipes

Watermelon stars in fruit salads, adding a burst of sweetness and color. Combine cubed watermelon with feta cheese, mint, and a drizzle of balsamic for a refreshing appetizer. For a unique twist, grill watermelon slices and serve with a sprinkle of salt and lime juice.

In savory dishes, watermelon pairs well with prosciutto or as a base for fresh salsa. The rind can be pickled for a tangy condiment. Watermelon seeds, when roasted, make a nutritious snack.

Desserts benefit from watermelon’s natural sweetness. Try watermelon sorbet, granita, or popsicles for cool treats. Watermelon juice can be reduced to create a syrup for cocktails or drizzled over cakes.

Summer Refreshments

Watermelon juice is a staple summer drink, easily made by blending the flesh and straining. For added zing, mix with lime juice and mint. Watermelon smoothies offer a nutritious option – blend with yogurt and berries for a creamy texture.

Cocktail enthusiasts can create watermelon margaritas or mojitos. For non-alcoholic options, infuse water with watermelon cubes and cucumber slices for a spa-like refreshment.

Frozen watermelon cubes make excellent ice cubes, adding flavor as they melt. Try blending frozen watermelon with coconut water for a slushy treat. Watermelon agua fresca, popular in Mexico, combines pureed watermelon with water and a touch of sugar.

Growing and Harvesting

Successful watermelon cultivation requires proper planting techniques, optimal growing conditions, and careful harvesting methods. Attention to soil preparation, watering, and timing are crucial for producing sweet, juicy melons.

Cultivation Practices

Choose a sunny location with well-draining soil for watermelon plants. Prepare the soil by incorporating compost or aged manure to improve fertility and drainage. Plant seeds directly in the garden 7-14 days after the last frost date.

Create small hills or mounds spaced 36 inches apart. Sow 6-8 seeds per hill, 1/2 inch deep. Once seedlings emerge, thin to the strongest 2-3 plants per hill.

Water deeply and consistently, especially during fruit development. Mulch around plants to retain moisture and suppress weeds. Fertilize with a balanced organic fertilizer every 3-4 weeks.

For smaller varieties like Armenian cucumbers, plant in rows 3 feet apart with 12 inches between plants. Ash gourds require similar spacing to standard watermelons.

Harvesting Techniques

Watermelons typically mature 70-100 days after planting, depending on the variety. Look for these signs of ripeness:

• Tendril nearest the fruit turns brown and dry
• Underside of melon changes from white to creamy yellow
• Skin loses its glossy appearance
• Thumping produces a hollow sound

To harvest, cut the stem 2-3 inches from the fruit using clean, sharp pruning shears. Avoid twisting or pulling, which can damage the vine.

Handle melons carefully to prevent bruising. Store at room temperature for up to a week or refrigerate cut melons for 3-5 days.
