All of these are bush type. So your choices should be what you like best. I prefer crooknecks lime Horn of Plenty or Summer Crookneck. If you like starightnecks Superpik or Early Prolific. I prefer the Mediteranian/Lebanese type zucchini like Profit or Barque. Dark Green zucchini Senator or Fordhook. Partenon if you need to grow under row covers. I have not grown the long yellow zukes for years, but do like round zukes, for yellow Sunday or One Ball. I also like scallops which come in colors from white to extra dark green.
