Seed paper — plantable paper, seeded paper, call it what you like — is handmade paper with living flower seeds pressed right through the sheet. Print on it, hand it out, and when it’s done its job the person holding it can plant it, water it, and grow wildflowers from what would otherwise have been bin-fodder. It’s the only piece of print marketing with an afterlife.
How seed paper is made
Proper seed paper starts as recycled paper pulp. The pulp is blended with water, seeds are folded through the wet mixture — not sprayed on the surface, which is the shortcut some producers take — and the sheets are formed, pressed, and dried. At our workshop the drying is done by hand, in small batches. That’s slower than machine drying, but it keeps temperatures down (seeds are alive, and heat is their enemy) and it gives every sheet the soft texture and visible seed flecks that make people keep the thing rather than bin it.
The result is a thick 300gsm sheet — heavier than most greetings cards — flecked with seeds you can see and feel.
How does printing not kill the seeds?
This is the question that matters, because a lot of “plantable” print out there will never grow a thing. Seeds die at sustained high temperatures — and most commercial printing is hot. Laser printers and digital presses fuse toner to paper with rollers running well over 150°C. The print looks lovely; the seeds are cooked.
The answer is cool-running inkjet. Ink is laid onto the sheet with no fusing heat at all, so the seeds arrive at your door as viable as the day they went into the pulp. It’s why we print exclusively with inkjet techniques refined over fifteen years — and why, if you’re printing your own blank seed paper at home, we’ll tell you to use your inkjet and avoid the office laser.
What grows out of it?
Ours comes in two papers. The wildflower mix grows a bee-friendly spread of blooms; the poppy paper grows a single striking flower. Either way, the growing part works the same: tear the paper up, lay it on compost, cover with about 5mm more compost, water well, and keep it moist somewhere bright. Expect shoots in two to four weeks — faster in spring and summer, slower but still willing in autumn.
What people use it for
Wedding invitations are the classic — an invite guests literally plant in the garden after the day. Beyond that: business cards that never see a bin, event flyers with a second life, orders of service, swing tags, packaging, and blank sheets for craft projects. Anything paper can do, seed paper does with a better ending.
Quick answers
Does seed paper really grow?
Yes — if the seeds were embedded in the pulp and the printing was done without high heat. Cool inkjet printing keeps seeds viable; hot laser or litho printing kills them.How long does seed paper last before planting?
Stored flat, cool and dry, it germinates well for around twelve months. The seeds are alive, so fresher is always better.Is seed paper recyclable?
Better than recyclable — it’s compostable and plantable. If it doesn’t get planted, it breaks down harmlessly.Can I write or print on it myself?
Yes. It takes pens beautifully and prints well on any home inkjet set to a heavyweight paper setting. Avoid laser printers — the fuser heat damages the seeds.
