Giant Moonflower seeds for the garden that has decided it deserves better than the garden centre allows. The Giant Moonflower opens at dusk and closes at dawn, which is a commitment most people could not manage.

Giant Moonflower is a climbing tropical vine with enormous white fragrant flowers that open only 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 Giant Moonflower from Seed

Sowing and Germination

Nick seeds and soak 24 hours. Direct sow or start indoors 4-6 weeks before last frost.

Care and Harvest

Large white fragrant blooms open at dusk and close by morning. Climbing vine to 4m. Tropical.

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.
