Mustard Greens seeds for the kitchen garden that intends to actually produce mustard greens this year. Mustard Greens grow with remarkable speed and the kind of flavour that improves everything it accompanies.

Mustard Greens is fast-growing peppery greens best harvested young and eaten quickly, before they develop opinions. 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 Mustard Greens from Seed

Sowing and Germination

Direct sow in spring or autumn. Fast germination. Harvest young for milder flavour.

Care and Harvest

Peppery, nutritious greens. Cut-and-come-again. Bolts in heat. 30-40 days.

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.
