Here are some factors to consider when choosing which Zucchini to grow:
1. Plant size. Most heirloom zucchini varieties are big, sprawling plants. If you have a small amount of space to devote to zukes, choose a bush variety: Custard White, Nero di Milano, or Novodiamant. 2. Fruit shape. Most zucchini are long and slender, which makes them good for slicing lengthwise for the grill or crosswise for salads and sautés. Some are round like baseballs—Tondo di Piacenzaand Tondo di Nizza— which makes them perfect for stuffing. Or go halfway with Bolognese, which has short, thick fruit. 3. Ribbing. If you like them smooth, try Genovese. If you like them heavily ribbed (which makes for interestingly shaped slices), tryRomanesco. If you like them in between, tryStriato d'ItaliaorVerde d'Italia. 4. Flowers. If you want to grow squash exclusively for squash blossoms, tryda Fiore, San PasqualeorAlbarello sel. Valery, varieties selected for their high proportion of flowers. (If you don't pick all the flowers, you will get some squash.) If you want both blossoms and a good zucchini, try Lunga Fiorentino. 5. Pest problems. If your zucchini plants are usually plagued by cucumber beetles or squash bugs, try growing a Zuchetta, which is a different species (Cucurbita moschata) and more resistant to pests. We haveTromba d'Albengaand Rugosa Friulana. Picked young, these two zuchettas have similar taste and texture to zucchini.
