Peruvianus

GH5

Partially documented

Also written as gh5

GH5 is a Peruvian torch collected from a wild population rather than bred in a garden. Its selling point is colour: a heavy blue-grey bloom over pronounced ribs and well-developed spines, with the intensity said to move with light levels. The code is the collector's own — the letters stand for Gains Harrison, the number for one selection out of that field work.Too little stands behind this for us to confirm it.

what the record holds

No source in this library records a cross for GH5. Nobody names a mother or a father for it, and no other entry here names it as a parent.

That is the record, not an oversight: of the 749 names in this library, 693 have no recorded relation either. Most named clones were selected, cut and passed along without anyone writing down what they came out of. A parent goes in here when a source states it and never because a name looks like one — a wrong pedigree would travel further than a blank one, because pedigrees get copied.

If you know where it came from, tell us — a person reads everything before it appears.

Notes
The is strongly , which is the reason collectors want it.Reported, but not confirmed.Ribs stand out and are pronounced, with matching wild Peruvian columnar plants.One source states this, and our house botanist has checked it. Prominent ribs, pronounced areoles and that spination are all normal for columnar plants of this group.How deep the blue runs is reported to shift with how much light the plant gets.One source states this, and our house botanist has checked it. The waxy bloom and blue cast do vary with light exposure, so shifting depth of colour is expected.

What the sources say

Everything on the wiki page rests on a single contributor's statement, and the wiki itself marks the entry unverified.Too little stands behind this for us to confirm it.
