About
Large blocky bell peppers with thick, juicy walls that stay crisp when green and sweeten as they turn red. Plants carry heavy foliage that shades fruit and reduces sunscald, with sturdy stems that hold the load. Use them the same way as any sweet bell: stuffed, sliced raw, grilled, or roasted.
Backstory
Corneli Seed Company of St. Louis listed Keystone Resistant Giant in its 1954 catalogs as a California Wonder type selected for larger size and tobacco mosaic virus resistance.
