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[1]. This species has escaped from cultivation and become an invasive weed in countries such as Hawaii, S. Africa and Australia[1]. The flowers open of a night time and are sweetly scented to attract bats and moths[2].
Propagation
Seed - usually germinates quickly and well without pre-treatment, though fresh seed may have a short dormancy of up to 8 weeks, Washing the seed in water prior to sowing can shorten germination time. The seed sometimes germinates whilst still in the fruit[1]. Cuttings. Vegetative reproduction is frequent in nature when stems break and detach from the parent plant. The stems can proceed to produce roots along tissue nearest to the ground and produce a new plant[1].
