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 Y2K 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.

The story

Y2K is known for developing increasingly bizarre growth as it matures, with irregular rib formations, distorted growth, skipped areoles, self-terminations, and the unmistakable "Y2K funk". It is also loved for its beautiful glaucous color and chunky growth. No two plants seem to express quite the same way.

Family line

Grandparents: SS02, Bridgesii family; SS01, Peruvianus family. Parents: Kimnach, Pachanoi family; SS02 × SS01, no page of its own. This cultivar: Y2K.

Over time

Photographed over 34 days — June 2026 to July 2026, on 3 different days.

  1. June 2026

    A single Y2K column standing in a garden bed under flat light, plainly ribbed and dark green up the lower two thirds, then breaking into knobs and bumps with rust-colored spines toward the pale new tip, with a small pale stone Buddha sitting in the bark behind it.

  2. July 2026

    The top of a Y2K column in flat evening light, its ribs swollen into broad rounded lobes with a deep groove down the middle and only a few yellow spines along the flanks; below, it narrows into an older section at a tan corky ring.
    A fat, pale blue-green column in a black nursery pot, its ribs bulging into uneven lumps the whole way down, short yellow-tan spines set far apart, and one branch pushing out low on the right, over bark mulch in low warm light.

  3. July 2026

    A swollen, lumpy head sitting on a much slimmer stem, the join ringed with dried tan tissue and long dark spines coming off it; behind, a mulched bed of upright columns and a black nursery pot.
