Y2K

Grown herePartially documented

Y2K is a selection out of a named seed batch, and the batch is written down. Our own catalogue records the grower Toadstool Todd picking it out of a Misplant sowing made as Kimnach by SS02 crossed with SS01 — which puts a documented behind a plant most collectors know only for how strange it gets with age. On the mother-first convention that places Kimnach on the seed side and the SS02 by SS01 line on the side, so the father here is a line rather than one named plant.Reported by one source, and not corroborated anywhere else.

PeruvianusNamed clone: One original plant and every cutting taken from it, given a name by a grower.

Of the 11 things this page says, 10 name who reports them and 1 is marked as something we cannot confirm. Where a line is not settled, it says so underneath.

Every ring is that plant’s own seal, in its family’s colour — open one to keep going.

Each plant wears its own seal here, coloured by its family — so a cross shows which side brought what before you read a name. A dashed ring is a plant with no page here yet, and a wire is only ever drawn from a parent somebody wrote down. Children are worked out from the other entries rather than stored on this one, so recording a cross anywhere lights it up on both plants.

The line matters as much as the box. A medium line is a cross on record as a report.

Drawn 3 generations each way. Everything our sources record for this plant is in the drawing; the family stops there, not the tree.

Recorded in our own catalogue as a selection out of a batch written Kimnach by SS02 crossed with SS01; on the mother-first convention that puts Kimnach on the seed side and the SS02 by SS01 line on the pollen side, which is how the cross is written rather than something the account states separately. Because the father is an F1 line, no single pollen plant can be named.Reported by one source, and not corroborated anywhere else.

The longer version

The owner records it as picked out of a seed batch by a named grower.Reported by one source, and not corroborated anywhere else.

Crosses are written mother by father, which is the convention the community's own seed pages set out.Reported by one source, and not corroborated anywhere else.

Skin: — that dusty blue bloom.Reported by one source, and not corroborated anywhere else.
Ribs: Irregular, with that get skipped.Checked and judged by our house botanist; no outside source states it. Skipped areoles and irregular ribbing are a normal expression of disordered growth in this genus.
Growth habit: Increasingly bizarre with age, terminating itself and starting again.Reported by one source, and not corroborated anywhere else.That pattern of alternating normal and strange growth is documented across generally.One source states this, and our house botanist has checked it. Alternating normal and disordered growth is typical of monstrose plants, so the description is consistent.

What the sources say

No source outside this yard records the name.Reported by one source, and not corroborated anywhere else.Matching the catalogue's bare word Kimnach to the accessioned Kimnach collection filed elsewhere in this library is a match of names, not something either account states.Reported, but not confirmed.

Filed under the same family, Peruvianus. The better-documented ones come first.

Links go to the channel, the subreddit or the front page of a site — never to one video, one post or somebody else’s product page. Nothing above is copied from any of them: every entry is written fresh from a fact list, with the source recorded against each fact as it went in.

Written from scratch off a cited fact list, never copied. Learned from the sanpedrocact.us community wiki (CC BY-NC 4.0), @sanpedromastery6262 and @IMDAVESBUD on YouTube, r/sanpedrocactus and medicactus.com's buyer guides, then checked against university extension horticulture, botanical gardens, cactus and succulent societies and the published botanical record. I will not name a plant from a photograph.
