About

The conical fruit runs about 5 to 8 cm long with thick, smooth walls. Pods are pale waxy yellow at horticultural maturity, then pass through orange before they turn red. Flavor is tangy and a little sweet, with medium heat that many people find gentler than a green jalapeño. Compact upright plants, usually 45 to 90 cm, set fruit steadily and carry resistance to tobacco mosaic virus pathotype 0. Yellow fruit is the classic pickle harvest. Red-ripe fruit is sweeter and works in salsa or sauce.

Backstory

Paul G. Smith released Caloro at the University of California, Davis in 1967 as a tobacco mosaic resistant yellow wax for California growers. In Mexican markets the same fruit class is sold as güero. It is a wax pepper, not a jalapeño, even though many packets use that nickname.
