Triamble PUMPKIN or Shamrock WINTER squash SEEDS

Triamble Pumpkin | Shamrock Winter Squash

Cucurbita maxima — Also known as Triangle, Tristar, or Shamrock Squash

A Living Heirloom from Down Under

Imagine harvesting a striking three-lobed, slate-blue squash that has graced gardens since 1918 — first in Australia, then exported to the United States in 1932 by Arthur Yates & Co. of Sydney. The Triamble is not just a squash; it's a piece of horticultural history you can grow in your own backyard.

Why Gardeners Love Triamble

• 🍂 Exceptionally sweet, dense flesh — rich flavor that holds remarkably long after harvest
• 🏡 Outstanding storage life — keeps well into winter, making it a true pantry staple
• 🌿 Rare & unique appearance — the distinctive three-lobed shape turns heads at markets and on the table
• 🌍 Heritage variety — documented in Australian seed catalogs as early as 1918

Growing Guide

• Days to maturity: 110–120 days
• Direct sow: Plant seeds outdoors in 12" diameter hills after all danger of frost has passed
• Spacing: Hills should be spaced 6 feet apart in all directions to allow vigorous vines to spread
• Head start indoors: Start seeds inside 3 weeks before your last frost date, then transplant out

Whether you're a heritage seed collector, a market gardener, or a home cook who loves a deeply flavorful winter squash, the Triamble delivers season after season.
