Romaine Lettuce seeds for the kitchen garden that intends to actually produce romaine lettuce this year. Romaine lettuce grows with the kind of upright confidence that suggests it has always known what it would become.

Romaine Lettuce is the classic upright romaine lettuce with crisp texture and sweet flavour that holds well in the heat. 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 Romaine Lettuce from Seed

Sowing and Germination

Direct sow in spring or autumn. 0.5cm deep, thin to 25cm. Cool season crop.

Care and Harvest

Upright heads with crisp, sweet flavour. 75-80 days or harvest leaves earlier. Slow to bolt.

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.
