4678 - Squash, Guatemalan Blue Banana. (Cucurbita maxima) Belongs to the Banana group of squashes, noted for their fine table quality. This selection is dark “blue” with light stripes; golden-yellow flesh is thick and firm. Fruits range up to 20 inches in length and average 5 pounds. We like to keep this one in the refrigerator after the initial cutting and continue to slice off small rings that can be either baked or roasted. 90-95 days.
