For Canadians: Seed Paper vs Regular Paper, What Actually Grows

Seed paper is paper made with embedded viable seeds and recyclable fibres, so it can be planted and grown, while regular paper is designed for writing and printing and usually isn’t meant to germinate anything. We’ve been making plantable cards in Canada long enough to know that planting success still depends on the seed type and how the paper is planted. The difference isn’t just sentimental. It changes what happens to the paper after you’re done with it.

TL;DR:

  • Seed paper is made from recycled fibers with embedded seeds, requiring gentle drying and light handling to ensure germination success.
  • Heavy printing, coatings, or exposure to heat can damage the seeds and reduce the paper’s plantability; testing printers beforehand is recommended.
  • Proper storage involves keeping seed paper dry and at room temperature to prevent premature germination or mold before planting.
  • Successful growth depends on planting the right seed species for your climate, using appropriate soil, and following correct planting procedures.
  • Choosing seed paper with clearly listed seed species and sustainable sources minimizes ecological risks and enhances planting confidence.

What seed paper is and how it’s made versus regular paper

Seed paper starts as pulp, often from recycled office paper, newspaper or cardboard, that gets broken down with water into a soft slurry. Once that pulp cools, seeds are blended in by hand or machine before the mixture is pressed into sheets and air-dried rather than heat-dried, which protects the seeds inside. The result is a thick, slightly textured paper that looks handmade because, in most cases, it is.

Regular paper takes a different road entirely. Industrial mills prioritize sizing agents, bleaching and coatings that make paper smoother, whiter and more resistant to ink bleed. Those additives are exactly what make most regular paper unsuitable for planting: they’re formulated to resist moisture and decomposition, not invite it.

A few production differences stand out:

  • Seed paper is air-dried at low temperatures to keep embedded seeds alive, while regular paper is often heat-pressed and dried at higher speeds.
  • Post-consumer recycled fibres are common in seed paper because the pulping process already breaks the paper down to a stage where adding seeds is simple.
  • Regular paper frequently includes bleaching chemicals and coatings for printability that have no equivalent purpose in a plantable product.

Using post-consumer recycled fibre also closes a loop that virgin paper never does: old paper becomes new paper, then eventually becomes part of a garden.

How seed paper performs for printing, durability and storage

Seed paper handles light use well, but it has limits worth knowing before you commit it to a big project. Handwriting and light ink stamps work fine, but anything involving heavy heat, like laser printing or foil stamping, can damage the embedded seeds or scorch the paper’s texture. Inkjet printing in small doses is usually the safest middle ground.

Storage matters more with seed paper than with regular paper. Keep it dry and at room temperature, since moisture and humidity can trigger early germination or mould long before the paper reaches a garden. Regular paper, by contrast, tolerates a much wider range of storage conditions because it isn’t carrying anything alive.

  • Seed paper suits cards, tags, invitations and other items meant for a single, memorable use.
  • Regular paper remains the better choice for long-term records, archival documents or packaging that needs to survive rough handling.
  • Avoid laminating, gluing or heavily coating seed paper, since all three block both printing quality and the seeds’ ability to grow later.

Pro Tip: If you’re printing on seed paper at home, run a test sheet first. Printers vary, and a thick, textured sheet can jam or smear in ways standard paper won’t.

How to plant seed paper and what germination actually looks like

Planting seed paper is simple, but a few details make the difference between a card that grows and one that sits in a drawer. The process follows a short, repeatable sequence.

  1. Soak the seed paper in water for a few hours or overnight to soften it.
  2. Fill a small pot or a patch of garden soil with seed-raising mix or loosened soil.
  3. Lay the paper flat on top and cover it with a thin layer of soil, no more than a few millimetres.
  4. Water gently and keep the soil consistently moist until seedlings appear, typically within one to three weeks depending on species.
  5. Thin out crowded seedlings once they’re a few centimetres tall so the strongest plants get room to grow.

Lab trials from 2025 found that seed paper can produce germination rates comparable to or higher than other plantable formats like seed balls, when planted correctly. That’s a meaningful data point for anyone assuming a novelty card can’t compete with directly sown seeds.

Several factors still decide whether a seed paper card actually produces flowers. The seed species needs to suit your climate and growing season, since a wildflower blend bred for one region may struggle in another. Paper thickness and seed density affect how evenly seeds are distributed, and paper that’s been stored somewhere damp or too warm may have lower viability by the time it’s planted. Our own guide on how to plant seed paper walks through these variables in more detail, including seasonal timing for different seed types.

What happens to the paper afterward: composting, waste and emissions

Seed paper is designed to end its life in soil or an organics bin, not a landfill. That matters more than it might seem. Federal guidance on municipal organics processing points out that diverting biodegradable, organic-rich paper away from landfill reduces methane emissions that form when paper breaks down without oxygen. Coated or laminated regular paper, by comparison, often can’t be composted or recycled cleanly at all.

What happens to the paper afterward: composting, waste and emissions — overview diagram

Canada generates roughly 6 million tonnes of paper waste annually, and coated or laminated paper streams see recycling rates around 25%, far below what uncoated, post-consumer paper achieves. That gap is exactly where seed paper’s simpler composition offers an advantage: less coating means fewer barriers to composting or recycling.

A few caveats are worth keeping in mind:

  • Confirm seed provenance before planting anything you didn’t grow from a known source.
  • Avoid seed paper with vague or unlisted seed mixes, since species not suited to your region can become invasive.
  • Favour post-consumer recycled paper over virgin fibre wherever possible, since it reduces upstream demand on forests.

How to choose between seed paper and regular paper for your project

The right choice usually comes down to what happens after the paper is used. If you want something printable, durable and meant to be kept, regular paper is the practical answer. If the goal is a gift, a one-time keepsake or something that leaves a living trace, seed paper does something regular paper simply can’t.

  • Match the paper to your goal: crisp print quality and archival life favour regular paper, while plantability and sentiment favour seed paper.
  • Consider the recipient’s interest in gardening, since seed paper works best for someone willing to plant it.
  • Ask suppliers for seed identification, recycled-content proof and clear planting instructions before buying.

Pro Tip: Treat vague seed mixes, glossy coatings or missing planting instructions as red flags. A trustworthy plantable paper product tells you exactly what’s inside it and how to grow it.

Why we design seed paper the way we do

We build every card from 100% post-consumer recycled material embedded with non-GMO, non-invasive seeds, and we make them in Canada rather than importing a finished product. That choice shapes everything from the pulp we source to the seed varieties we select, since we only use species that are safe to plant across a wide range of home gardens.

We also know that a plantable card is only as good as the instructions that come with it. Our planting and troubleshooting guide and our wildflower planting walkthrough cover the details buyers actually ask about: soil depth, watering frequency, what to do if nothing sprouts after a few weeks. For readers comparing broader sustainability claims across paper products, our own sustainability audit of plantable cards breaks down the materials and lifecycle questions worth asking any supplier.

Our take: plantability matters more than the marketing around it

The seed paper market leans hard on the feel-good angle, and that’s fair since growing a card into a plant is genuinely satisfying. But the detail that gets glossed over is seed provenance. CFIA guidance on seeds bought online flags a real risk: packets without listed species can introduce plants that don’t belong in a given region, and a well-intentioned gift can quietly become an ecological problem.

Our stance is that plantability without transparency isn’t much of an upgrade over regular paper. The paper itself matters less than what’s growing inside it. If you’re choosing a seed paper product, the planting instructions and seed list deserve more scrutiny than the texture or the packaging. Buy from a supplier who names the species, not just the colours of the flowers on the box.

FAQ

Does seed paper actually work?

Yes, seed paper germinates reliably when planted correctly, with lab trials showing germination rates comparable to or better than other plantable formats. Success depends on soaking the paper, covering it lightly with soil and keeping it consistently moist.

What paper to use for seed paper?

Seed paper is typically made from recycled pulp such as used office paper, newspaper or cardboard, since these break down easily into the slurry seeds get blended into. Non-coated, untreated paper works best because coatings and heavy inks interfere with both pulping and germination.

How long can seed paper last?

Seed paper stays viable for planting as long as it’s stored dry and at room temperature, away from humidity and direct heat. Moisture is the main threat, since it can trigger early germination or mould before the paper ever reaches soil.

Can you print on seed paper?

Light inkjet printing or handwriting works well on seed paper, but heavy heat processes like laser printing or foil stamping can damage the embedded seeds. Testing a sample sheet first is the safest way to confirm your printer handles the texture properly.
