Weird Worm

Partially documented

Weird Worm is a , import from Brazil, described by the grower who brought it in. The odd growth is the attraction and also the problem: it is unstable and prone to fungal trouble, so the grower sprays a fungicide and keeps on hand in case a piece needs rescuing. No species, count or spine detail is recorded.Too little stands behind this for us to confirm it.

  • monstrose
  • variegated
  • fungus-prone
  • keep graft stock

what the record holds

No source in this library records a cross for Weird Worm. 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
Health: the odd growth is fickle and inclined to fungal trouble, so the grower treats it with the fungicide mancozeb.Too little stands behind this for us to confirm it.Propagation: the advice is to keep grafting stock ready, because the plant does better kept on its own.Reported, but not confirmed.

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.
