Watercress Vegetable Seeds Packet
Couldn't load pickup availability
Watercress seeds for the kitchen garden that intends to actually produce watercress this year. Watercress is the vegetable that grows in water, which is either a solution to the irrigation problem or an entirely new one.
Watercress is a peppery aquatic green that grows in shallow water or constantly moist soil and delivers exceptional nutrition. 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 Watercress from Seed
Sowing and Germination
Sow in spring in constantly moist or shallow water. Can be grown in containers kept very wet.
Care and Harvest
Needs constant moisture or shallow water. Harvest young stems. Peppery, nutritious. Cut-and-come-again.
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.
We stand by the quality of our flower seed packets! With high germination rates and vibrant blooms, your garden is sure to flourish. If you're not completely satisfied, we’ll replace or refund—guaranteed!

Types of Seeds We Offer
Hybrid Seeds (F1)
F1 hybrid seeds are the garden’s high achievers — created by crossing two specially chosen parent plants for superior vigor, uniformity, and performance. We use only traditional breeding methods to produce these powerhouse seeds.
Open-Pollinated & Heirloom Seeds
Our open-pollinated (OP) seeds naturally reproduce through wind, insects, water, or self-pollination. When grown in isolation, they produce true-to-type plants year after year.
Among our OP seeds are treasured heirloom varieties — old favorites that have been carefully passed down for generations. While OP plants can be less uniform than hybrids, we run our Open-Pollinated Project to select the most reliable, flavorful, and beautiful strains. Many are also available as certified organic seeds.
Non-GMO: What It Means and Why It Matters
A GMO (Genetically Modified Organism) is created when scientists alter a plant’s DNA in a lab — often by inserting genes from completely unrelated species — to achieve certain traits, like pest resistance or herbicide tolerance. This is a far cry from natural plant breeding.
At Shido, we believe gardening should stay as close to nature as possible. All our seeds — whether hybrid, heirloom, organic, or open-pollinated — are Non-GMO. They’re bred using traditional methods that respect natural biodiversity, giving you safe, wholesome seeds that grow into plants just as nature intended.
When you plant Shido Non-GMO seeds, you’re choosing purity, sustainability, and peace of mind — along with a garden full of flavor, color, and beauty.
Vacuum-Sealed for Freshness — Good for 10 Years
Every Shido seed packet is vacuum-sealed to lock in freshness and protect your seeds from moisture, air, and pests. This careful packaging not only preserves their quality but also extends their shelf life dramatically. Stored properly in a cool, dry place, our seeds remain viable for up to 10 years — so you can plant them now, next season, or even years down the road. Whether you’re planning a garden this spring or building a long-term seed stash, Shido seeds are ready when you are.
