45 days. Truly living up to its name, Goliath produces very large, 9-inch, dark green cukes with a pale green interior, up to four inches in diameter. The plants are heavy producers and adaptable to different climates while boasting a good disease package. Straight, uniform fruit with smooth skin that doesn’t turn bitter makes it the perfect addition to salads and fresh veggie platters! MO. CMV, DM, PRV.
