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.
Nasturtium officinale. True Watercress seeds produce a perennial cress that is rich in vitamins and has a delicious, distinctive taste for salads and vegetarian dishes. Little, dark-green leaves grow on crisp stems that come from thick, long roots. Direct-seed watercress about 5mm (1/4") deep and 1cm (1/2") apart, ideally in full sun near clear running water. Thin plants to 10cm (4") and keep very well watered. Watercress does not thrive in acidic soil, so spread enough lime in the growing area to bring the pH as close to 7.0 as possible. Well finished compost is the other trick that will keep watercress growing rapidly. If you fail with watercress in your summer garden, try planting it beneath a cloche row cover for winter harvesting. The low light levels and cool temperatures seem to be ideal.

We Recommend
We Recommend: West Coast Market Mix (MS489) isn’t just for the West Coast. It’s a fast-growing blend of lettuces, chicories, arugula and herbs intended to be harvested as baby greens. Tasty! Enjoy repeated harvests of crisp and succulent salad greens.
For Urban Gardeners: City Garden Blend (LT450) is lovely. Several different seeds are pelleted together, so you only need to plant three or four pellets in a 3 to 5 gallon container. Watch as a beautiful selection of different green and red lettuces grows in, and then start harvesting! This blend requires very little space, and can be accomplished on a sunny windowsill.

Timing
Timing
Seed every three weeks from just before the last frost date until the end of summer for a continuous harvest. Provide frost protection with a cloche or heavy row cover when frost looms in the fall. Many mesclun types and mixes will continue to grow all winter where winters are mild.
Starting
Starting
Plant in a block or in a wide row. Sprinkle the seeds evenly over prepared, moist soil. Try to space seeds about 1cm (½”) apart. Cover lightly with soil, and firm them in. Four grams of seed will plant a 12m (40′) row that is 7cm (3″) wide, so don’t plant the whole packet at once. For container growing, choose containers that are at least 10cm (4″) deep. Wider is better. The most common mistake is over-planting.
Growing
Growing
Moderately fertile soil – particularly if you’re planning multiple harvests. Dig in 1 cup of complete organic fertilizer for every 3m (10′) of row. For containers, use peat or coir based mix with compost added. Water regularly. If growth slows after harvest, use a bit of kelp or fish based fertilizer to provide a boost of nutrition for the next growth spurt.
Harvest
Harvest
There are two methods of gathering salad greens. You can use scissors to cut everything about 2-5cm (1-2″) from the ground, when the plants are about 10-15cm (3-4″) tall. Or, you can pick individual leaves as they’re needed. The first cutting may contain more brassicas than lettuces (arugula, mizuna) but if you cut the mix back when the leaves are still small, the lettuce will catch up. The salad greens will regrow for a second harvest in another 2 or 3 weeks.

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.
