Round Zucchini Seeds – Heirloom Round Summer Squash for Stuffing, Roasting and Grilling

Round Zucchini is a unique heirloom summer squash known for its small globe-shaped fruits and tender zucchini flavor. These attractive round squash are harvested young while skins are smooth and glossy, producing compact fruits that are perfect for stuffing, roasting, and grilling.

Productive bush plants grow quickly in warm summer gardens and produce abundant harvests throughout the season. The compact growth habit makes round zucchini easy to grow in backyard gardens, raised beds, and larger containers while still producing reliable yields.

The round fruits have a mild, slightly sweet zucchini flavor and tender flesh. Their natural bowl-like shape makes them especially popular for stuffed squash dishes, while their texture also works well for sautéing, grilling, and roasting.
