At first glance, both are long, green, and grow on bushy plants. But the stem tells the story: zucchini stems are smooth and round, while squash stems crack and flake at the base.
Zucchini skin is usually uniform and dark green, sometimes with faint stripes. Squash, on the other hand, often wears a yellow necklace right where the fruit meets the stem.
Fun fact: In Italy, zucchini are called zucchine and are treated like delicate pasta. In the U.S., we call them summer squash, but botanically, they’re the same species—Cucurbita pepo.
Growing Differences: The Plants in Your Garden
If you’re a gardener, you’ll notice the leaves first. Zucchini plants have deeply cut, almost jagged leaves with silvery spots. Squash leaves are broader, rounder, and more matt in texture.
Zucchini plants tend to be bush-type, staying compact and tidy in a raised bed. Squash varieties, like yellow crookneck, often send out rambling vines that wander five feet from home.
Practical tip: If you only have a small patio, go for zucchini. It’s the apartment-friendly cousin of the two.
