Two years ago I grafted a 2 cm (~0.8'') wide Lophophora williamsii v. caespitosa cutting on a Trichocereus bridgesii stock. The main head has now grown to a width of 5.5 cm (~2.2'') and the total width of the scion exceeds 10.5 cm (~4.1'') – unfortunately the plant hasn’t flowered yet.

Grafted Lophophora williamsii v. caespitosa
I’ve given up keeping count of the number of offshoots; the plant is virtually exploding with growth.
Trichocereus bridgesii is an exemplary stock plant; it’s long-lived, fast growing, not offsetting and almost spineless.
Last year I also posted a picture of the – then much smaller – Lophophora williamsii v. caespitosa graft. A photo of the flowering plant can be found in this post.
