Cultivation Details

The genus Harrisia is found in semi-arid tropical to subtropical regions of the Americas, growing in both the northern and southern hemispheres. There is usually a dry season at the cooler part of the year that can last up to 6 months. Annual precipitation is generally around 500 - 1,200mm. In the northernmost part of its range, in Florida, and in its southwestern range in Argentina and Bolivia, it experiences occasional freezing temperatures, and in cultivation light frosts (1-2 per year) experienced by species in Florida, seemed well-tolerated and not detrimental[
