Triamble Squash Seeds – Rare Heirloom Winter Squash, Blue-Green Fruits (25 Seeds)

Triamble Squash is a rare heirloom winter squash prized for its distinctive three-lobed, triangular shape and striking blue-green skin. The fruits typically weigh 6 to 10 pounds and store well, making them a valuable addition to the fall and winter harvest. The deep orange flesh is dense, sweet, and smooth, ideal for roasting, soups, and baking. This Australian heirloom dates back to the early 20th century and is relatively uncommon in modern gardens, offering growers a unique and productive winter squash.

Triamble Squash grows on vigorous vines that can spread 10 to 15 feet, so provide plenty of space or a sturdy trellis. The plants are generally resistant to common squash pests and diseases, and the fruits mature in about 100 to 110 days from transplant. Whether you are an heirloom enthusiast or a market grower looking for a standout variety, Triamble delivers both visual appeal and excellent eating quality.

Planting & Care

Sow Triamble Squash seeds indoors 3 to 4 weeks before the last frost date, or direct sow outdoors after the soil has warmed to at least 70°F. Plant seeds 1 inch deep in rich, well-drained soil. Provide full sun and consistent moisture, especially during flowering and fruit development. Mulch to conserve moisture and suppress weeds. Vines can be trained onto a sturdy trellis to save space, but support the heavy fruits if growing vertically.

Harvest when the skin is hard and the stem begins to dry and turn brown. Cut the fruit with a few inches of stem attached and cure in a warm, dry, well-ventilated area for 7 to 10 days before storing. Store cured squash in a cool, dry place at 50 to 55°F for several months. Monitor for pests and diseases, and rotate crops to avoid soil-borne issues.
