Silky, snow-white pattypans with a gently fluted crown arrive at maturity like small porcelain saucers—tender, mild, and delicately sweet.

Their firm, fine-grained flesh holds its shape beautifully, offering a satisfying bite whether you savor them fresh or roast until lightly golden. White Flat Boer is a standout for gardeners who want abundant, attractive fruit that shines in summer displays and performs reliably from bed to basket for sauces and quick pickling.

Culinary Notes


Chef's Note

White Flat Boer pattypans are mild and sweet with flesh that stays composed—perfect for high-heat cooking where you want browning without mush. Think crisp pickles or lightly charred rounds: they hold their shape, take on lemon-vinegar brightness, and make an elegant little platter without tasting “too squash-y.”

Best Uses

  • quick pickling for crisp, fluted rounds
  • roasting or sautéing until the flat edges brown and caramelize
  • light summer sautés with herbs and lemon to keep the sweetness clean
  • thin-slice skillet cooking for bite-sized, shape-holding pieces

Frequently Asked Questions


What pest or disease problem is most common on Cucurbita pepo (white flat boer), and how do I treat it?
Powdery mildew often shows up on Cucurbita pepo as a white, powdery coating on leaves during warm, humid spells. Remove the most heavily infected leaves early, then improve airflow by training plants to sprawl less and spacing them adequately; avoid wetting foliage when watering. If it keeps spreading, use a labeled sulfur-based fungicide or potassium bicarbonate at the first signs and repeat according to the product label.
How often should I water Cucurbita pepo during the main growing phase, and what soil moisture target should I maintain?
During active vine and fruit growth, keep soil evenly moist but not soggy—aim for about 1–1.5 inches (2.5–4 cm) of water per week, adjusting for heat and rainfall. Water deeply at the base when the top 1–2 inches (2.5–5 cm) of soil dry out, because Cucurbita pepo roots struggle in waterlogged conditions. Reduce watering slightly once fruits are sizing up to avoid split or watery fruit.
How can I tell when Cucurbita pepo (white flat boer) is ready to harvest?
Harvest at about 95 days when the rind has turned fully hard and the surface color looks mature (for white types, a creamy white rather than pale/greenish). The stem should start to dry and the fruit should feel heavy for its size; press the rind with a fingernail—if it resists denting, it’s ready. Cut the fruit with a bit of stem attached and cure it warm and dry for better keeping quality.
