Deliciously sweet Italian peppers turn a rich shade of purple when they are fully ripe, adding a beautiful new color choice to Marconi peppers. Expect plentiful harvests of these peppers, which become about 6-in. long with a tapered shape ending in a blunt tip. Traditionally used for frying, Marconis are also wonderful when eaten fresh. Create a beautiful salad with Purple Marconi, either by itself or in combination with the red and golden versions. 90 days.
