10"-ish Sherman tip cutting.
Bridg? Peru/bridg hybrid? I don't know. In my eyes, it doesn't matter. It's Sherman :)
Sherman is a clone near and dear to me. It's named after an old-timer here in Phoenix who I've spent a lot of time cactusing with.
This is another Arizona plant that can handle FULL Arizona sun once established. In shady locations and through the Winter months, it develops a deep blue hue.
