SWIM seal. Plain ring: nothing here sets a rib count, a spine length or a growth form the ring can mark.

SWIM

Name only

SWIM is one of the named selections growers pulled out of Ikaros DNA seed batches, listed on the community record beside Althea as a pick from that Peruvian seed line. That one line of parentage is everything our sources hold: no count, spine detail or description of the plant itself has been written down, so for now the name marks a documented origin rather than a described cactus.Reported, but not confirmed.

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

Of the 4 things this page says, 4 are 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 dashed line is a cross we can report but cannot confirm. Every cross drawn here is at that weakest reading, which is the true state of this plant's record.

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

Recorded as a named selection pulled out of the Ikaros DNA seed line, alongside Althea. Because that line is a variable seed population rather than a single , the honest phrasing is that SWIM was selected out of it — not that Ikaros DNA is a parent in the ordinary sense. The father, some plant in an open-pollinated wild stand, was never recorded.Too little stands behind this for us to confirm it.

The longer version

Those batches come from wild mother stands that are pollinated in the open, so which plant fathered any given seedling was never recorded.Too little stands behind this for us to confirm it.

Nobody has described the skin, the ribs or the spines of this one anywhere we could cite, so there is nothing here to draw or to list.

What the sources say

No source we have found argues about this name — nobody has written that it is confused with another plant, or that two growers mean different things by it. That is worth knowing in itself.
