Overview

Cucurbita pepo 'Spaghetti' is spaghetti squash (vegetable spaghetti), a trailing vining annual growing 12-18 inches (30-45 cm) tall and 96-144 inches (240-360 cm / 8-12 feet) wide. Oblong yellow-skinned winter squash 8-12 inches (20-30 cm) long and 4-5 inches (10-13 cm) diameter, weighing 4-8 pounds (1.8-3.6 kg). The cooked flesh separates into spaghetti-like strands — the cultivar's defining trait. Bright yellow funnel-shaped flowers — separate male and female on the same plant (monoecious). Dark green large palmate foliage with light green veining. In the gourd family (Cucurbitaceae). Classified as C. pepo (not C. maxima or C. moschata). Winter squash — harvest mature when rind turns deep yellow and cannot be dented with a fingernail. Requires 100-110 days from seed — a limitation for short-season climates. Vines require 8-12 feet (240-360 cm) of space. Squash vine borer (Melittia cucurbitae) and powdery mildew are primary pests/diseases. Stores 2-3 months at 50-60°F (10-16°C). Open-pollinated — cross-pollinates with other C. pepo. Non-toxic (edible crop). Tender annual. Full sun. Growth rate is fast.
