Come summer, there's always zucchini on the menu! How lucky for us that something so delicious is also a prolific grower. National "Sneak Some Zucchini into your Neighbor's Porch Day" is August 8, about the time when zucchini crops across the country abound.
Enjoyed as a vegetable but actually an immature fruit, zucchini is a relative of the cucumber and the melon. Formerly called Italian squash—the word "zucchini" comes from the Italian word for small squash, "zucchino"— it was likely introduced to the United States by Italian immigrants in California in the early 1920s.
Zucchini takes just about 50 days from planting to eating. It's not cold hardy, but it'll grow easily in many parts of the world, including throughout the United States. And it comes in all sizes, from just a few inches to the largest zucchini to date, grown in Niagara Falls and measuring 8 feet 3 inches.
The zucchini is an excellent source of manganese and vitamin C and a very good source of magnesium, vitamin A, dietary fiber, potassium, folate, copper and phosphorus. It's a good source of omega-3 fatty acids, vitamins B1, B2 and B6, calcium, zinc, niacin and protein.
The edible flowers are a good source of beta-carotene and vitamin C.
The best known of the summer squash, there are at least 50 varieties of zucchini, from smooth, long, thin specimens (Fascienne and Cocozelle) to squat and round ones (Black Ball and Lucky 8). Skin colors range from yellow (Golden Girl and Grenade) to dark green (Nano Verde di Milano) and some with striped or speckled skin (Green Tiger and Lucky 8). There's even a rectangular variety (great for grilling) called Green Griller and a grey-skinned variety, called Greybeard.

Zucchini is available throughout summer, and its peak season is May through August.
Small to medium-sized zucchini are generally more tender than older, larger vegetables (the vegetable develops more seeds and becomes tougher as it gets larger).
Look for bright, blemish-free skin, and avoid zucchini with soft spots. It should be firm and heavy for its size. If the rind is too hard it may be over-mature.
Take care not to puncture the skin, or the fruit will decay more quickly. Store zucchini unwashed in a perforated plastic or vegetable bag in the refrigerator for up to a week.
