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.
Technically a wax bean until it develops its purple streaks, this beautiful Dutch heirloom is wonderful to eat fresh, or to save and use as dried beans. When the flat 21–25cm (8–10”) beans turn from a lime green to yellow with bright purple stripes, they are ready for cooking or freezing. Dragon Tongue bush bean seeds are also known as Merveille de Piemonte.

Direct sow from mid-spring to early summer. Try to plant during a warm, dry spell. Soil must be warm – if it is not warm enough, the seeds may rot, especially our untreated seeds. Optimal soil temperature for germination: 21-32°C (70-90°F). The seeds should sprout in 8-16 days, depending on conditions.
Starting
Starting
Sow seeds 2-5cm (1-2″) deep, 5-8cm (2-3″) apart, in rows 45-60cm (18-24″) apart. Thin to at least 15cm (6″) apart in each row. If the weather is too wet, beans can also be started in pots indoors and set out carefully a few weeks later. For a continuous harvest, plant at 3 week intervals.

Growing
Growing
Ideal pH: 6.0-6.5. Well drained, warm soil in full sun is best. Raised beds help with both drainage and warmth. Use 1 cup of complete organic fertilizer for every 3m (10′) of row. Too much nitrogen fertilizer is often the cause of poor pod set and delayed maturity. If the plants flower but do not set pods, the cause may be zinc deficiency. Try spraying the plants with kelp-based fertilizer. Wet leaves on crowded plants are subject to diseases. Thin plants to increase air circulation and avoid touching the leaves while they are wet.
Harvest
Harvest
Pick beans regularly to keep the plant producing (if pods get fat with seed, the plant will stop flowering). The smaller the bean, the more tender they are.

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.
Direct sow mid-to late spring. Try to plant during a warm, dry spell. Soil must be warm—if it is not warm enough, seeds may rot, especially since our seeds are not treated with fungicide. Sow drying beans as early as possible, so they can mature before rainy/cold weather sets in. Optimal soil temperature: 21-2°C (70-90°F). Seeds will sprout in 8-16 days, depending on conditions.
Sow bush bean seeds 2-5cm (1-2”) deep, 5-8cm (2-3”) apart, in rows 45-60cm (18-24”) apart. Thin to at least 15cm (6”) apart in each row. If the weather is too wet, beans can also be started in pots indoors and set out carefully a few weeks later. For a longer harvest, plant at 3 week intervals.
