A jam-jar cutting is the one heirloom that's still growing

A jam jar of water on a windowsill, drawn in cream and pale green. One leafy cutting stands in it, roots just visible through the glass. Behind it, the same plant, grown large in a pot. A hand enters from the edge of the frame, holding a second cutting.

Every plant in that chain is both a copy of the one before it and the same plant, still alive. Nothing else handed down in a family works that way.

Why does the picture show two scales of the same plant, not one?

Because the argument is the relationship between them, not either plant on its own.

A single cutting in a jar just looks like a cutting in a jar — pretty, temporary, not obviously significant. Put the grown plant behind it, and the jar stops being a snapshot and becomes a stage in something ongoing: this small thing is going to become that large thing, the way it already has once before. Grafting works on the same principle — a cutting isn't a copy of the plant, it's a continuation of it, started again from a different point.

Why is a rooted cutting both a copy and the original at once?

Because cuttings don't reproduce a plant the way seeds do — they're the same living tissue, detached and given a new root system.

A seed carries a new combination of genes and grows into a related but distinct individual. A cutting is genetically identical to the plant it came from, cell for cell, so the one on the windowsill and the one behind it in the pot aren't parent and child the way two people are — they're the same organism, split and continuing in two places. Neither is more the real plant than the other.

Why does it matter what species this actually is, rather than just a houseplant?

Because different plants propagate, and hold a family's story, in different ways.

A pothos or a spider plant divides easily and keeps going almost indefinitely, which is exactly why those are the ones that get handed down for decades. A plant that's fussier to root, or that only a few people in the family have managed to keep alive, tells a slightly different story about who has the patience for it. Drawn generically, none of that survives; drawn as the actual species, the leaf shape alone tells anyone who's kept one which plant this is.

What is the hand entering the frame from the edge doing there?

It's mid-action, taking a second cutting — the picture catches the plant being passed on rather than sitting still.

Left out, the drawing would just be a still life: jar, plant, done. The hand makes clear this isn't the end state, it's one frame in a sequence running longer than anyone currently holding a cutting has been alive, and set to keep running after them. Unlike a set of keys to houses nobody in the family lives in any more, this is an heirloom that's still doing something.

Who owns a houseplant that's been divided for generations?

Almost always, nobody — the common houseplants passed hand to hand this way are old varieties with no patent on them at all.

A small number of modern cultivars are patented and restrict propagating them for sale, but that rule is aimed at nurseries multiplying stock to sell, not at a cutting given to a relative. An heirloom already several generations of cuttings deep, with nobody able to say which garden centre it started in, is about as far from that situation as a houseplant gets.

Should the print name the person the plant came from, or leave it unnamed?

Either is a complete version, and the two are arguing different things.

Naming the person turns the shirt into a specific line of inheritance — this plant, from this person, on this date. Leaving it unnamed keeps the print about the mechanism itself: that a cutting is a copy and a continuation regardless of whose windowsill it started on. Neither reading is the more honest one.

Does the same idea work as a gift, especially for somebody far away?

Yes, and a cutting travels in a way most inherited objects can't.

A piece of furniture or a photograph can only be handed down in person or shipped whole. A cutting can go in an envelope, root in a new jar hundreds of miles away, and still be the same plant it left. A gift built around exactly that distance runs on the same logic — the object matters less than the fact that it physically crossed the gap.

Does it print well?

Yes — a two-colour line drawing with a clear line between light and dark leaves plenty of room for the roots and the hand to stay legible.

Cream and pale green on olive keeps the cutting distinct from the grown plant behind it without needing a third colour; the leaf shapes just need to stay true to the actual species rather than generic foliage, since that detail is what makes it recognisable.

How do I get one made?

Describe the plant at JustOG — the species, whose windowsill it's on, and whether to name where it came from. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.
