About

Marconi peppers, also called Giant Marconi or Marconi Red, are elongated Italian sweet peppers that can reach 8 to 12 inches in length and about 3 inches across at the shoulders. The fruits taper to a point and have thin walls with a crunchy texture, ripening from glossy green to deep red, golden yellow, or even purple depending on the cultivar. They offer a mild, sweet flavor with subtle smoky undertones that intensifies when cooked, making them perfect for Italian dishes, salads, sauces, and stuffing. Plants are compact, bushy, and productive, typically reaching 2.5 to 3 feet tall with high yields. The variety includes both heirloom strains from southern Italy and improved hybrids like the AAS-winning Giant Marconi. They are versatile for home gardens and excel in Mediterranean-style cooking.

Backstory

Heirloom variety from southern Italy (regions like Calabria and Campania), improved in the US with the Giant Marconi hybrid winning All-America Selections in 2001 for its earliness, yield, and flavor.
