I grow a variety of summer squash called trombomcino (it's is very long and somewhat shaped like a trombone) and tastes like zucchini. Also it vines rather than makes a bush. The description said it was unique, implying there are no other vining summer squash. Th advantage of vining is if part of the plant is attacked by SVB then you can bury the stem and it will make new roots and survive the attack. Keep us posted on what happens with Dunja.
