Scallops/Patty Pans Group
One of my favorite groups for eating. The fruit needs to be picked small for best flavor and texture. UPDATED FOR 2021
Yellow Summer Squash Group
This group has the straightnecks and crooknecks and are typically what a lot of folks refer to as yellow summer squash. Best to harvest when 6 inches or less but the fingernail test is best. If it bruises easily when pricked with the fingernail it is still young and tender and ready to eat.
The traditional group of what people refer to as zucchini, usually shades of green, and long, slender fruit.
Summer Marrow Group
The group that is typically white skinned or pale green with some exceptions. Flesh is usually a little firmer than traditional zucchini.
The ones in this group do not fit into any group because of unique traits or growth patterns that they have.
