Zucchini is probably the most reliable of warm season vegetable through summer, even when tomatoes are having a bad year. A single zucchini plant produces enough for a household. Two plants produce enough to share with neighbors. Pattypan, crookneck and other varieties of summer squash may not be quite as reliably productive individually, but can be assembled as a delightfully variable team that produces early in summer, and is just now finishing.
The fruit of summer squash is best when immature and tender. It gets tougher and loses flavor as it matures. Because development of seed within maturing fruit exhausts resources, plants are actually more productive if the fruit gets harvested while immature. In other words, they can either make many small fruits, or a few large fruits. The plants have coarse foliage on big but relatively confined annual plants.
Winter squash is very closely related to summer squash. The shabby annual vines sprawl over much larger areas, and can even climb fences and shrubbery. The main difference though, is that each plant produces only a single fruit or only a few individual fruits that are allowed to mature completely through summer. Their ripening fruit is just now becoming available as summer squash are running out. The fruit is supposed to be best after frost has killed the foliage, which could take a while here.
Hubbard, acorn, turban, spaghetti, kabocha and butternut squash, as well as the many varieties of pumpkin, are the more popular types of winter squash. Unlike summer squash, winter squash can be stored for quite a while, and need to be cooked to be eaten. While winter squash do not produce as many fruiting female flowers as summer squash produce, they seem to make at least as many male flowers that can be harvested while still fresh.
Male flowers can be stuffed, battered and fried, or simply fried. After they have been pollinated and set fruit, female flowers are typically too wilted to be eaten. All squash produce more male flowers than female flowers. Even the most fruitful of summer squash produce about three times as many male flowers as female flowers.
Actually, it is a fruit; a rather BIG fruit. It happens to be one of the more familiar of winter squash, but is not too commonly eaten. Although it makes excellent pie, and provides edible seeds and flowers, pumpkin is more popularly known as jack-o’-lanterns or Cinderella’s ride to the ball. Pumpkin is not for every garden, since each big and coarsely foliated annual vine needs regular watering, rich soil and considerable space to grow all through summer to produce only one or two big fruit in autumn.
Most pumpkins are big and round, and have smooth and bright orange skin. Those grown for jack-o’-lanterns are brighter orange, and not quite as meaty. Those grown for pie are often a bit smaller and meatier, with a rustier orange color. The biggest pumpkins get too huge to move easily, but lack flavor. The flavors and densities of many weird modern varieties are as variable as the green, red, pink, yellow and white hues of their skins. Some pumpkins have been developed specifically for their seeds, which are known as pepitas, or are used for production of pumpkin seed oil.
