Oxalis seeds for the garden that has decided it deserves better than the garden centre allows. Oxalis has a charming habit of closing its leaves and flowers at night, which is more discreet than most plants manage.

Oxalis is a delicate clover-leafed plant with cheerful flowers that open in sun and close at night. Each packet is hermetically vacuum-sealed -- removing the oxygen that causes standard paper seed packets to lose germination viability within approximately one year. State law requires a 3-year viability label on sealed packaging. NASA research on hermetic seed storage indicates viability of up to 10 years under proper conditions. Every packet is non-GMO and germination-tested at independent third-party labs before it earns its Japanese woodblock print artwork.

How to Grow Oxalis from Seed

Sowing and Germination

Sow indoors or plant corms. Spring planting for summer bloom.

Care and Harvest

Clover-like leaves with white, pink, or yellow flowers. Container or border plant.

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, the Toronto ceramics studio 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.
