Grouping
Hybrid
A hybrid is two plants crossed on purpose, and the name usually records which two. It is a group rather than a species, because the whole point of a cross is that it does not sit cleanly in either parent's description.

Worth knowing
A cross name read backwards is not evidence of anything — several well-known crosses are written in both directions by different growers.
A clone name is not proof of a species, and a photograph is a pointer rather than an answer.

Names in the library
The seal draws the plant behind the name where the ring can mark it: the ribs, the spines, the growth form. A plain ring has nothing marked on it.

Every photograph in the yard pages and the shop is of a plant grown here, except where a listing says it was grown by somebody else — it says so on the listing, above the price.
