Shishigatani Squash Seeds, Rare Kyoto Heirloom

Since the early 1800s, Shishigatani has been one of the official kyo yasai , the traditional vegetables of the Kyoto region, a short list of heirlooms so tied to Japanese culture that the regional government formally protects them. Buddhist priests have grown this squash in temple gardens and cooked it in shojin ryori, the austere, vegetable-centered cuisine of Zen monasteries, for generations. It is one of the oldest continuously cultivated vegetables in Japanese history.

And almost nobody in the American seed market carries it.

Shishigatani is unmistakable. The deeply ribbed and warted skin starts green and slowly turns a warm tan-brown as it ripens, developing a texture that looks almost ancient. At 110 to 120 days it has one of the longer maturity windows in our catalog, but patience pays off. The flesh inside is a delicate pale yellow, completely different from the orange of most winter squash, with a fine-grained, dry texture and a mild, clean sweetness that disappears entirely in soups and braises. It holds its shape exceptionally well when cooked, which is why Buddhist temple cooks have used it for centuries in dishes where the vegetable needs to carry the meal without falling apart.

It is not a loud vegetable. It is a precise one.

Shishigatani is Cucurbita moschata, the same species as Seminole, Thai Kang Kob, and Waltham Butternut. That matters for Kansas and Midwest gardeners because moschata varieties carry natural resistance to the squash vine borer, the pest that kills most backyard squash before it produces anything worth harvesting. You do not need to spray. You do not need row covers. The plant handles it.

Plant after last frost when soil is warm. Give it room to run or train it up a trellis. Water deeply and step back. At 110 to 120 days it is one of the slower maturing squash in the garden, so plan your start date accordingly for your region.

• Species: Cucurbita moschata
• Days to maturity: 110 to 120 days
• Flesh: Pale yellow, fine-grained, dry texture
• Skin: Deeply ribbed and warted, turns tan-brown at maturity
• Vine borer resistance: Yes, naturally, as C. moschata
• Seed saving: Open-pollinated, non-GMO. Save seed from your best fruit and replant every year.
• Plant after: Last frost, soil temperature 60 degrees or above
• Spacing: 4 to 6 feet between plants, or train vertically on a trellis
• Use: Soups, braises, tempura, shojin ryori, roasted whole

The pale yellow flesh and dry texture make Shishigatani better suited for some preparations than the denser orange moschata varieties. It absorbs broth and seasoning beautifully without going mushy, which makes it exceptional in slow-cooked soups and Japanese-style simmered dishes. Cut into large pieces, simmered in dashi with a little soy sauce and mirin, and it becomes something genuinely extraordinary. It also roasts well whole, and because the flesh is drier than most squash, it holds together cleanly when sliced.

If you have never cooked with a pale-fleshed squash before, the flavor is milder and more delicate than orange-fleshed varieties. It pairs well with subtle broths and seasoning rather than aggressive spice.
