Winter squash is also a warm-season vegetable, although this type is harvested when fully mature and it's skin has hardened. At this stage, squash can be stored in a cool, dry storage area for the winter (hence the name). They are mostly vining type plants and need lots of room. They can be trellised to save space in the garden.
Plant in the spring after the last chance of frost in a rich, well-drained soil, in full sun.
Note: All squash flowers are edible.
