Giant Aconcagua is a scrumptious, gigantic sweet red pepper from Argentina that commands attention in any garden. These heirloom plants tower over 3 feet tall and produce abundant peppers, each reaching nearly 12 inches long with thick, juicy flesh that's remarkably sweet. Mature fruit appears in 75 to 85 days, and the plants thrive in full sun with warm temperatures between 70 and 85°F. Grown as an annual in most climates, it becomes perennial in frost-free zones, rewarding patient gardeners with generous harvests of frying peppers that rival store-bought quality.

Giant Aconcagua produces enormous, thick-walled peppers that are surprisingly juicy and exceptionally sweet, making them a standout choice for frying and fresh eating. The plants grow tall and vigorous, reaching over 3 feet, and they need staking as the weight of dozens of peppers loads the branches. The sheer productivity of these plants, combined with the premium quality of the fruit, creates a genuinely thrilling growing experience that justifies the space and attention they demand.
Giant Aconcagua excels as a frying pepper, where its thick flesh and high juice content create tender, juicy results when cooked quickly over heat. The large size and sweet flavor also suit it well to fresh eating, whether sliced raw into salads or stuffed whole with grains, cheeses, or vegetables. The abundant production means gardeners often preserve some as roasted peppers or freeze them for winter use.

Start seeds indoors 7 to 14 days before your last frost date, sowing them 1/4 inch deep in warm soil maintained between 70 and 85°F. Transplant seedlings outdoors after the soil has warmed thoroughly and all frost danger has passed, typically 8 to 10 weeks after sowing.
Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days. Transplant into garden beds or containers when soil temperatures reach at least 60°F and nighttime lows stay above 50°F. Space plants 18 to 24 inches apart in full sun.
Harvest peppers when they reach full size, approximately 10 to 12 inches long, and have turned deep red. They'll feel firm and glossy to the touch at peak ripeness. Use a sharp knife or pruners to cut peppers from the stem rather than pulling, which can damage the branches. Harvesting regularly encourages continued flowering and fruiting throughout the season.
Prune lower branches as the plant grows to improve air circulation and make staking easier. Remove any competing central leaders to encourage a single, strong main stem that's easier to support as it bears heavy fruit.
