Whale Spinach is an F1 hybrid variety that produces dark green, nearly smooth, elongated leaves on short upright plants. Known for its resistance to 7 races of downy mildew, Whale Spinach has moderate tolerance to bolting and good heat resistance which allows for summer crop production with this variety. Often grown as a baby-leaf variety for its notably tender and uniform flat leaves which make a delicious addition or base green for mixed salads. 25 days. Packet: 250 seeds.
