roof buster

Well documented

Also written as Roof Buster

Roof buster is a sales name, not a : in 2021 one grower's cuzcoensis plants got tall enough to push through the shade cloth over the growing area, so the tops were cut and sold under that name, partly to move a that was not selling. Anything bought under the label is a cuzcoensis, and specimens may include material from that grower's 2006 seed-grown . They are fast and get big, so they want height or open sky. This is a useful worked example of a market name that describes a situation rather than a genetically distinct plant.Too little stands behind this for us to confirm it.

what the record holds

No source in this library records a cross for roof buster. 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.

The longer version

Species, as our sources record it: cuzcoensis, which the wiki page says is frequently marketed as "peruvian torch".Reported by one source, and not corroborated anywhere else.

Several of the grower's cuzcoensis plants grew tall enough to stretch up and push through the shade cloth over the growing structure.Too little stands behind this for us to confirm it.

Those tall cuts were sold under the roof buster name, partly to shift a variety that was less popular than the rest of the stock.Too little stands behind this for us to confirm it.

Some of the material may also have come from seed-grown KK stock raised in 2006.Too little stands behind this for us to confirm it.

The better-selling plants were pruned more often and so never got that high: among them Cactus Kate , Rimac, Wild Andes, , the one billed as "fastest", and Juuls.Too little stands behind this for us to confirm it.

Where the name comes from

The name started in 2021 with the grower Verne, who is associated with Cactus Kate.Too little stands behind this for us to confirm it.

Character

A bar is drawn only where one of the lines below states it — never from the species, never from a photograph.

  • slow and steady to fast grower: this one leans towards fast grower, read from the growth line below.

Growth habit
Fast, and capable of real height — they need high clearance indoors or a spot outdoors.One source states this, and our house botanist has checked it. Vigorous growth and substantial height are normal in this genus, so tall clearance or outdoor space is a fair requirement.
Notes
appearance: the plants show the ordinary cuzcoensis look, with heavy and tall columns.One source states this, and our house botanist has checked it. Heavy spination and tall columnar growth are ordinary for this species and nothing in the description falls outside the genus.

What the sources say

The wiki page carries a banner saying it was assembled by a bot from community chat and has not been checked by an editor. The wiki page says plainly that the label describes a sales situation rather than a genetically distinct plant, which cuts against how a buyer would normally read a name.Too little stands behind this for us to confirm it.The plants were also sold under the label "peruvian torch" while being cuzcoensis, so the same material has circulated under two misleading names. The mislabelling this entry complains about is a real species-level error, not a naming quibble: the current treatment keeps Trichocereus cuzcoensis as a species distinct from macrogonus, so a cuzcoensis sold as a peruvian torch is being sold as something else.Reported, but not confirmed.
