Why Vacuum-Sealed Seeds Last Longer
Standard paper seed packets are permeable to oxygen and moisture -- the two primary causes of seed degradation. Most paper-packaged seeds begin losing germination viability after approximately one year, contributing to significant garden-industry waste: packets purchased, not planted, expired, discarded. Shido Seeds are hermetically vacuum-sealed. The packet does not expire quietly in a drawer. It waits.
About the Packaging
Every Shido seed packet is illustrated in the style of Japanese 1910s woodblock printing -- designed and drawn in-house by Chive, that has been exhibiting at the Chelsea Flower Show in London every year and does not, as a matter of principle, sell to big-box retailers. Customers collect the packets as a series. This was not the original plan.
We stand by the quality of our flower seed packets! Every Shido seed packet is lab-tested for germination before it ships. If your seeds do not perform to the stated germination rate under correct growing conditions, contact us and we will replace or refund. Guaranteed!

What makes Shido Seeds different
Shido Seeds are designed by Chive Studio, a ceramic design company. We are not a seed conglomerate. We do not sell through big-box retailers. Each variety in the catalog was selected because it is worth growing — not because it ships well in bulk or photographs well in marketing materials.
Every packet is germination-tested at an independent third-party lab before it earns its woodblock illustration. The vacuum seal removes the oxygen that causes standard paper packets to degrade. The stated germination rate is a floor, not a marketing figure.
If something goes wrong, contact us. We will make it right.
