TBMB

Also written as TBM-B

TBMB (Trichocereus bridgesii monstrose 'B') grows in knobby, stacked segments, and no two plants take the same shape.

Read the reference entry → — what the name TBMB means, where it came from, and what other growers record about it.

One of these is in the shop right now.

Each listing is one specific plant, photographed as it is today.

The story

Each one develops its own character, which is most of the fun of growing it. In California's climate it thrives in full sun once acclimated, staying compact with excellent color.

Photographs
