Poona Kheera (Seed Savers Exchange)--(Cucumis sativus) Originally from Poona, India, this very unusual cucumber matures into what looks like a large russet potato. Smooth-skinned fruits turn from white to golden-yellow to russet brown and may be eaten at any stage, skin and all. Tender, crisp, and delicious. Hardy disease resistant vines produce an early crop with good yields. 55 days.
