West Coast Seeds ships anywhere in North America. However, we are not able to ship garlic, potatoes, asparagus crowns, bulbs, onion sets, Mason bee cocoons, or nematodes outside of Canada. We regret, we cannot accept returns or damages for orders outside of Canada. The minimum shipping charge to the US is $9.99.
For every order online, we donate a pack of seeds to gardens and communities worldwide through our Seeds of Growth program, supporting sustainable growth and local food systems.
Mild and sweet enough for salads, the thin, light-green, feathery leaves are deeply-cut but not curled. Plants grow vigorously so thin to at least 20cm (8"). Cut the whole plant about an inch above the ground and it will re-grow or pick individual leaves. Mizuna mustard seeds can be planted for cut and come again harvests, or grow to full size. Plant in late summer and provide frost protection - it will grow even under low light conditions. Note that it will bolt in April if overwintered. Mizuna works well in containers, and makes excellent, fast-growing microgreens and baby leaf salad greens.
Matures in 45 days. (Open-pollinated seeds)

Mustards are cool season plants that grow quickly and then bolt. Direct sow with frost protection as early as late winter or without protection from early to late spring. Sowing short rows every 3 weeks allows for a continuous harvest of both baby leaves and full sized plants. Sow again in late summer for late fall and winter harvests. Optimal soil temperature: 21°C (70°F). Seeds should sprout in 5-10 days.
Starting
Starting
If growing to full size, sow 3-4 seeds in each spot you want a plant to grow. Sow 5mm-1cm (¼-½”) deep and thin to the strongest plant, spaced 10-15cm (4-6″) in the row. All mustards can be grown in containers for baby salad greens. Sow these as you would mesclun mixes, with seeds spaced as near as possible to 1cm (½”) apart.
Days to Maturity
Days to Maturity: From direct sowing.

Ideal pH: 6.0-6.5. One cup of complete organic fertilizer will provide nutrition for 3m (10′) of row. Water regularly. Expect mustards to bolt in hot weather. Provide protection in winter by using a cloche or heavy row cover. At all other times, plan on growing fast and harvesting fast, like spinach. Planting short rows every two weeks works best for the home garden for a constant harvest.
Harvest
Harvest
Cut individual leaves, or the whole plant at whatever stage of maturity you desire. Young leaves tend to be more tender and less powerfully flavoured as mature leaves. Some varieties will develop a slight bitterness in fully mature leaves. The leaves can be blanched (or run through a food processor) and then frozen, or even dried and flaked for soup mixes. But the plants are so cold hardy, fresh leaves should be available to the determined gardener 12 months of the year. Whole plants can also be pickled for long term storage.

Diseases & Pests
Diseases & Pests
Slugs and woodlice (sow bugs) may nibble young seedlings, but overall, these plants are trouble free. Keep the garden free from debris and excess water, where both of these pests like to go during the day. If leaves show lots of tiny holes, flea beetles are the problem. Prevent early spring infestations by using lightweight row cover.
West Coast Seeds is a family-owned company that embraces an organic lifestyle. A group of imagination catalysts and passionate educators, dedicated to producing products and services that better the environment. As part of our mission to repair the earth, we aim to inspire and empower people to take responsibility for the state of the planet. For us, organic is about much more than saying no to chemicals, it is about saying yes to building a healthy soil for the future.
For over 35 years, we have upheld our strong reputation as a leading seed supplier, seeking out the highest quality untreated seeds for organic growing and putting them through rigorous independent testing. We built our company on the exchange of generational wisdom in a masterclass community of newbies and masters alike. Our world may have changed, but our commitment to our people, our customers, and our planet has not.
We’re a values-based business that has blossomed into a lifestyle ethos, with products that support seeders, feeders, keepers, and the tiniest of creepers. Our mission? To mobilize the next generation of gardeners with products that nourish soil and grow vigorous, sustainable gardens. We believe all plants should be grown without the use of chemicals, and that the seeds we supply are an important component of regenerative gardening.
We don’t just offer seeds, we offer experience, insight, and understanding. From timeless garden wisdom to new tech know-how, this is learning on the job: knowledge gleaned not from the pages of a book but from burying our fingers in the soil. We test, experiment, observe and adapt, never happier than when we get to share what we’ve learned with others.
Gardens don’t just grow seeds. They grow minds and imaginations, people and communities. Our vision encompasses both the micro and the macro. We eat locally, protect pollinators, teach people to grow from seed, and support regional biodiversity. We think big but act small and deliver unexpected impact — always with community and purpose.
At West Coast Seeds we believe in the power of small and that little can be large. Like the tiniest seed germinates to evoke incremental change with massive potential, so to can our community of gardeners and growers together. Gardeners are the earth’s stewards, planting seeds of creative declaration. The soil provides the canvas, we provide the seeds.
