Zucchini, Costata Romanesco (55 days) 

Delicious Italian heirloom summer squash produces pale green fruits with distinct ribs. Although it yields lower than hybrid varieties, its flavor is far superior - creamy, nutty and with great texture. Exceptionally large blossoms lend themselves to frying well.
