About

Aconcagua is an heirloom Capsicum annuum variety originating from Argentina and named after the towering Mount Aconcagua in Mendoza Province. This giant sweet pepper features elongated, cone-shaped fruits that commonly reach 9–12 inches (23–30 cm) in length and 2–3 inches in width, with thick, juicy walls and smooth skin. Fruits mature from green through yellow and orange stages to vibrant red, developing increasing sweetness and a fruity, almost apple-like character when fully ripe. Completely mild (0 SHU), it excels in culinary applications from fresh eating to roasting and frying. Vigorous plants grow over 3 feet (90+ cm) tall with heavy yields but require staking. It matures in approximately 75–85 days under warm, full-sun conditions with moderate watering.

Backstory

This variety takes its name from Mount Aconcagua, the highest mountain in both the Western and Southern Hemispheres, located in the Andes of Mendoza Province, Argentina. It is an heirloom likely selected from local cultivation or markets in Argentina and introduced to wider gardening circles by seed savers who appreciated its remarkable size and superior sweet flavor compared to standard sweet peppers.
