The top of a fat pale-green column with a crowd of small heads budding across its crown and two more pushing out of its sides, the body streaked and patched with gray corky scarring, in flat light over a gravel bed by a redwood fence.
Growing

CSD

A Trichocereus bridgesii whose mature growth turns thick, wrinkled and almost monstrous, with the melty look that makes CSD instantly recognizable.

Nothing off this one is listed at the moment. It's growing in the yard and gets cut when it's ready.

Tell me when it’s cut

When a cutting off CSD is listed, I’ll email you to say so (if you are not signed in, after you have opened the link I send first). I only have one of most things, so it is first come — nothing is held.

Email me when this is available. I understand this notice is about the plant I asked about, that I can opt out from any message, and that my address is not shared with anyone.

You'll get emails from the yard. Unsubscribe any time.

From my yard

  • This is very thick csd

    In my yard,

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

The story

CSD is a Trichocereus bridgesii that began as a seed-grown plant standing out for its unusual growth, and was named during a 2014 community giveaway in memory of a Shaman Australis member. Mature plants are known for their thick, wrinkled, almost monstrous growth and the characteristic melty look that makes CSD instantly recognizable. This is NOT a beginner's clone — CSD can be finicky, and it has a reputation for melting or developing cosmetic damage if conditions aren't right.

What it looks like

Skin
Reportedly vivid green with a glaucous finish.
Ribs
Reportedly, the apex forms geometric patterns of deep notches and sharply angled rib valleys.
Spines
Reportedly very short or missing altogether, set in tiny recessed areoles.

Over time

Photographed over 4 months — March 2026 to August 2026, on 3 different days.

  1. March 2026

    One column standing in bark mulch against a redwood fence, pale blue-green with thin white spines, a taller staked column blurred behind it and a striped pebble at its foot.
    Straight down onto a low, fat crown of blunt rounded ribs closing into a tight center, the pale gray-green skin blotched yellow, one thin tan spine standing out of each gray areole; red dirt and green weeds blur out below.

  2. July 2026

    The crown of a CSD column shot straight down in dim light, eight blunt rib tips swelling in toward the middle with their top faces butter yellow where the flanks stay blue-green. A purple flower head sits just behind at the top right.

  3. August 2026

    The top of a fat pale-green column with a crowd of small heads budding across its crown and two more pushing out of its sides, the body streaked and patched with gray corky scarring, in flat light over a gravel bed by a redwood fence.
