Each order gets you heirloom summer squash seeds.  I'm not sure of the exact variety, I've been growing these each year for over 20 years.  They do very well here in zone 7.  Vines are normal size; Fruits are best if harvested semi early so they don't get tough.  We canned these this year and they came out beautiful!  Certain types can up better than others, and this one is a gem!
