Fruit Type is usually the first consideration for gardeners thinking about which zucchini varieties to try, but vine size is also important, especially for small space or container gardeners.
Disease Resistance can also be a factor, especially if you're growing zucchini where particular diseases are prevalent.
Fruit Type. Green, cylindrical squash are what most people think of when they think of zucchini, but the color can vary from a solid, deep green, to lighter shades with streaks or blotches of darker green. There are also bright yellow and bi-color cultivars.
Zucchini can be smooth, or have pronounced ridges that produce star-shaped slices.
Shapes also vary from the typical long thin cylinder, to bulbous at one end, to egg-shaped and even round. Pay close attention to the size of harvest for each zucchini variety in the descriptions below, and try to harvest at or near that size.
Growing Zucchini Problems
Cylindrical zucchini should be harvested at the recommended size or smaller, while heirloom, bulbous zucchini can be harvested a little larger.

Flavor, of course, is another consideration. Most zucchini are bland, and take on the flavoring of what they're cooked with. They offer a pleasant, moist crunchy texture to vegetable sautes. But some have an almost nutty flavor. The Middle Eastern Cousa squash are known for deep flavor and dense flesh that stands up well to grilling.
Growing Zucchini In Containers
Vine Size and Habit are another thing to consider to when selecting among zucchini varieties. Even bush-type zucchini need 3-4' (1 m) of space to grow in. Heirloom and older zucchini types can be larger, and take up more space. They may also have spines on the stems of the fruit or ribs of the leaves.
Some heirloom and most of the newer hybrid zucchini varieties are selected for compact, bushy habits and minimal spines, so they're easier to harvest, and work better in small gardens.
If you don’t have much space, or if you’re growing zucchini in containers, look for compact bush varieties in the descriptions below. ‘Raven’, 'Black Beauty', ‘Bush Baby’, and ‘Patio Star’ are the best varieties for container gardeners.
Finally, Disease Resistance can be important for some gardeners. If you live in a wet climate, look for varieties with some resistance to powdery mildew, and allow more space between plants for better air circulation. If yellow mosaic virus is a problem in your area, look for resistant zucchini varieties.
