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.
Silverado Swiss chard seeds produce relatively compact plants that have heavily savoyed, deep, dark green leaves with bright white stems. A taste test favourite, its beautiful appearance and very high resistance to bolting make it a great home garden and market variety. Silverado will be ready to harvest as baby greens in only 25 to 30 days. Compared to some other varieties, this is a fairly slow growing chard that eventually reaches 35-40cm (14-16") in height. Harvest individual leaves by cutting from the base, or cut whole plants for easy transport and display on market tables.
Matures in 60 days. (Open-pollinated seeds)

Ideal pH: 6.0-6.5. Swiss chard prefers loose, deep, and fertile soil that is rich in organic matter. Plenty of consistent moisture is required, especially as plants grow larger. It grows best in full sun, but will tolerate light shade in summer. A liquid fertilizer or compost tea applied twice during summer will keep chard growing well.
Harvest

For salad mix, seed more densely and cut as baby leaves. Cut individual mature stalks using the large outer ones first.

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.
