Pattypan Squash
Cucurbita pepo
A scalloped summer squash with firmer flesh, and it stays good at a slightly larger size.

Firmer than a zucchini
Pattypan flesh is denser and less watery than zucchini or yellow squash, which means it grills, roasts and stuffs better and holds its shape in a pan. It is also slightly more forgiving if you miss a day of picking.
Pick small
Two to four inches across is the sweet spot - the whole fruit is tender and the seeds have not formed. At six inches or more the flesh coarsens and the skin toughens. Baby pattypans at an inch and a half are excellent whole.
Compact plants
The bush habit is generally tighter than other summer squash, which makes pattypan a good choice for a small bed or a large container. Still allow a full two to three foot circle.
Sow direct in warm soil
An inch deep, after last frost, in 65F+ soil. Rich soil with plenty of compost; squash are heavy feeders. Side-dress once flowering begins.
Pollination
The first flowers are male and drop; female flowers with a tiny fruit behind them follow. Fruit that shrivels at the blossom end was poorly pollinated - hand-pollinate in the morning with a brush if bee activity is low.
Squash vine borer
The same sudden-wilt killer as other pepo squash. Wrap the stem base, use row cover until flowering, or plant a second batch in early July after the main moth flight. Check the stem base weekly for frass.
Squash bugs and mildew
Crush the bronze egg clusters on leaf undersides before they hatch. Powdery mildew arrives midsummer - space widely and water at the base.
Harvest and storage
Cut with an inch of stem, every day or two. Keeps under a week refrigerated. Roasts and grills well; the shape makes it ideal for hollowing out and stuffing.
