Traditional Italian heirloom with great flavor.

This distinctive zucchini is medium gray-green, with pale green flecks and prominent ribs. Big, large-leafed, semi-vining plants with only about half the yield of hybrids, but much better flavor; clearly better textured, nutty, and delicious, raw or cooked. Also a good producer of heavy male blossoms for cooking.

  • Edible Flowers: Blossoms bear a mild, squash-like flavor and are great stuffed and fried, or sliced for used in soups, omelets, salads, and pasta dishes.

  • Packet: 25 seeds
  • Avg. 2,700 seeds/lb

SCIENTIFIC NAME

Cucurbita pepo

CULTURE

Fertile, well-drained soil with a pH of 5.8–6.8 is best. Plastic mulch and fabric row covers (AG-19 grade) can aide plant establishment and exclude insect pests during the seedling stage. Row covers should be removed when plants begin to flower. Poor fruit development may indicate insufficient pollination. For highest quality fruit, succession plantings every 2-3 weeks may be needed.

PLANT SPACING

Space plants 18-24" apart in rows 6' apart. Wider spacing may allow for easier harvesting.

DISEASES

Common cucurbit diseases include powdery mildew, downy mildew, bacterial wilt, and phytophthora. Avoid problems with adequate soil drainage, good air flow, insect pest control, and crop rotation. If necessary, check with your local Cooperative Extension Service agent for specific control options.

INSECT PESTS

Cucumber beetles, squash bugs, and vine borers are all common pests for cucurbits. Protect young plants with floating row cover. Squash bug eggs found on the undersides of leaves may be crushed by hand. For vine borers, cut out of vines and hill soil over the wound. Keep field borders mowed and remove plant refuse in the fall; spring plow to bury pupae. Pyrethrin sprays may offer some control.

HARVEST FRUIT

For some varieties, it is common for the first fruits to be malformed, wither, or blacken, which indicates poor pollination and is usually remedied as more male flowers appear. Harvest regularly, 2-3 times a week, once plants begin to produce. Cut or gently twist off fruits when they have reached the desired size. For zucchini, 6-8" long. Handle with care to avoid scratching fruits.

HARVEST BLOSSOMS

Harvest male blossoms (with thin stems) or female blossoms (with thick stems and an immature fruit at the base of the flower) in mid to late morning when fully open. Clip flowers 1-2" below flower base. If a squash fruit crop is also desired from the same planting, only harvest male flowers, leaving a few to pollinate the female flowers.

STORAGE

Keep fruit at 40-50°F (5-10°C), 95% relative humidity for up to 2 weeks. Use as soon as possible for best quality.

DAYS TO MATURITY

From direct seeding; subtract about 14 days if transplanting.
