Looking down into a shallow gray bowl planter packed with dozens of short knobby TBMB stems in dark grit, small yellow-green shoots pushing out from areoles here and there, with terracotta pots on either side and a speckled gray boulder behind.

From my yard

  • Tbmb has never flowered yet.

    In my yard,

My plants grow outdoors in Discovery Bay, California. Yours may do something different.

Sold recently

Proof this one does come up: these went in the last three months.

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.

What it looks like

Spines
A specialist reference says the spines show even on a small plant, which is one of the ways this form is told from the long one.
Growth habit
It reportedly grows in short, thick segments a few inches long that stop and put up new pups on top of and beside one another, slowly building a low, bushy clump. Plants in this yard grow in knobby, stacked segments, and no two take the same shape. Once acclimated they thrive in California full sun, staying compact with excellent color.

    Close in and low down: two blunt pale-green tips with long amber spines fanning across them and a dry tan scar on the nearer one, everything past them soft and out of focus.
