Kellogg's Breakfast tomatoes

Indeterminate · Solanaceae

Kellogg's Breakfast is a famous orange beefsteak heirloom grown for huge fruit, low-acid sweetness, and vivid juice color. Individual tomatoes commonly weigh 1 to 2 pounds, so plants need strong support and steady watering to avoid splitting. It suits gardeners who want impressive slicers and have room for an indeterminate vine.
