Highlights
The flesh deepens in flavor and sweetness as weeks pass in storage, rewarding patient gardeners with squash that tastes better in January than in October. At 6 to 10 pounds, each fruit is substantial enough to feed a family but still manageable to handle and store. The combination of ornamental blue-gray skin and intense orange flesh creates a plant that's as beautiful to look at in the garden as it is delicious to eat.
Common Uses
New Zealand Blue Squash excels in the kitchen as a roasted side dish, in creamy soups where its dense flesh breaks down into silken puree, and baked whole or halved. The fine texture and sweetness make it particularly suited to dishes that highlight the squash itself rather than using it as a neutral backdrop, so it shines in autumn bisques, grain bowls, and simple preparations with minimal seasoning.

Care Instructions
Direct Sow
Direct sow seeds after the last frost date when soil has warmed and all danger of frost has passed.
Harvesting
Harvest New Zealand Blue Squash when the skin has hardened and turned a deep blue-gray color, typically around 110 days after sowing. The stem will feel woody and resist puncture from a fingernail when ripe. Cut the squash from the vine with several inches of stem attached, which helps extend storage life. Handle carefully to avoid bruising, as any damage shortens how long the squash keeps.
