gh5

“gh5” is a distinct clone of Trichocereus (syn. Echinopsis) characterized by its striking glaucous blue epidermis. It exhibits prominent ribs, pronounced areoles, and a spine profile consistent with wild-type Peruvian columnar cacti. The blue coloration is highly sought after by collectors, with growers noting its intensity varies depending on environmental exposure.

The clone “gh5” is a wild-collected landrace Trichocereus peruvianus (Peruvian Torch) sourced by Gains Harrison. The designation “gh” directly corresponds to the initials of Gains Harrison, with “5” representing the specific selection or collection number from his field work.

As a wild-collected landrace T. peruvianus, “gh5” thrives in well-draining mineral soil mixes and benefits from deep, infrequent watering during the active growing season. To maximize the signature glaucous blue coloration of the epidermis, growers often experiment with light exposure, as the development of the waxy epicuticular bloom can be influenced by the balance between direct sunlight and partial shade.
