Sunburst is a pattypan summer squash, treat it exactly like a zucchini, it is a bush so it will not trail along the ground, The span will be about 4 feet across. They will not keep long,about the same time as a cucumber. Pick when small best at about three inches and keep picking, you can eat them when bigger but they are nicest samll and the more you pick the more you will grow.
Start one seed to a pot in three inch pots and you will only need a few plants. Unless you are a very big zuchinni fan or have a large family four should be tons.
