Decosta

Partially documented

Decosta is a New Zealand with a keeper's name attached to it. The traces to an old stand an elderly gardener had held for years, which the breeder Ross Gurau lifted and then sent out around the world. While the stand was being moved a large section came to light, and taken off it went on cresting under the new owner's care — the test that separates a heritable crest from a one-off deformity. Gurau ran a set of domes full of big mature and produced seed from them in quantity, so Decosta crosses have been grown out in gardens on several continents.Too little stands behind this for us to confirm it.

what the record holds

No source in this library records a cross for Decosta. 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

Gurau kept domes of large mature Trichocereus and used them to raise seed in quantity, which is why Decosta crosses turn up in gardens far from New Zealand.Too little stands behind this for us to confirm it.

Where the name comes from

The clone comes out of a long-standing New Zealand planting kept by an elderly gardener, which the breeder Ross Gurau relocated and then circulated internationally.Too little stands behind this for us to confirm it.

Growth habit
The mother stand carried at least one big crested section, and cuttings taken from it kept cresting afterwards.Too little stands behind this for us to confirm it.

What the sources say

The breeder has since stopped, sold the property and moved on, and nobody has reported back on the original stands, so their condition is unknown.Too little stands behind this for us to confirm it.Our own earlier note filed Decosta among names with no verified traits. That was accurate when it was written and the wiki page has since been filled in; the note is kept so the change is visible.Reported by one source, and not corroborated anywhere else.
