Spaghetti Squash Tivoli is a compact, bush-type winter squash that produces oval, pale yellow fruits filled with tender, spaghetti-like strands. When cooked, the flesh separates into noodle-like ribbons, making it a popular low-carb alternative to pasta. Tivoli is earlier and more compact than traditional vining types, making it ideal for smaller gardens and containers while still delivering reliable yields.
