Kakai Styrian Pumpkin — The Austrian Heirloom With Hull-Less, Oil-Rich Seeds Made for Roasting
The Kakai Styrian Pumpkin is unlike any other pumpkin you’ve grown. Developed in the province of Styria in Austria, this unique cultivar produces large, striking fruits — green ripening to striped orange-green — whose seeds have a thin membrane instead of a hard shell, making the entire seed fully edible without hulling. The seeds are high in oil and exceptionally delicious eaten roasted or raw, with a rich, nutty flavor that makes them a gourmet snack and a prized ingredient in Styrian pumpkin seed oil.
The plant itself is problem-free, fast-growing, and a prolific producer. The flesh is thin, bright yellow, coarse-textured, and tasty — a dual-purpose pumpkin for seeds and eating. 90 days.

Growing Notes
Direct sow outdoors after last frost when soil has warmed to at least 65°F. Prepare hills with compost or aged manure. Sow 3–4 seeds per hill, thinning to 2–3 strongest seedlings. For rows, space plants 3 feet apart. Keep weeded and watered consistently. Harvest at maturity when fruits turn from green to striped orange-green, or just after first frost. To save seeds: cut open, scoop seeds onto a screen, and work free of pulp by hand (avoid water). Spread on paper plates to dry, stirring several times daily. Store in paper bags.
