Wairoa x Gissy (Yearlings)

"Wairoa" is a specific cultivar of Trichocereus Peruvianus (a type of cactus) that originated from Ross Gurau's garden in New Zealand.
Ross Gurau is known in the Trichocereus community for cultivating and naming various cactus clones. Some of his other named clones include Church Hill, Sheridan, Decosta, Dane, Weka, Guru, Zephyr, Gissy, and Uawa, in addition to Wairoa.
Information about the specific origins and detailed history of Ross Gurau's collection, including Wairoa, can be somewhat limited, even within dedicated online communities like the "Trichocereus Origin & History Facebook group." However, it's mentioned that Ross Gurau is active on Facebook, suggesting direct contact might be a way to gain more information about his specific clones.

Origin: 'Gissy' is a clone that originates from Ross Gurau's garden in New Zealand. Ross Gurau is a well-known grower and breeder of Trichocereus cacti. 'Gissy' is listed among other named clones from his garden, such as 'Church Hill', 'Sheridan', 'Decosta', and 'Weka'.
Species: While not explicitly stated as pachanoi or peruvianus in every mention, its association with other clones from Ross Gurau's garden that are predominantly Trichocereus pachanoi suggests it is likely a form of Trichocereus pachanoi (San Pedro cactus).
Usage in Crosses: 'Gissy' is known to be used as a parent plant in hybridization, as evidenced by references to crosses like "Vawa x Gissy". This indicates it possesses desirable traits for breeding.
General Characteristics (as a Trichocereus clone):
Trichocereus species, in general, are known for being columnar, fast-growing, and relatively cold and wet tolerant.
They typically produce large, funnel-shaped, white flowers that often open at night.
They can be easily propagated from cuttings.
In essence, 'Gissy' is a named Trichocereus clone with a known origin in New Zealand, used in breeding programs, and shares the general characteristics of robust, fast-growing columnar cacti typical of the Trichocereus genus.
