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.
Perilla frutescens var. crispa. Red Perilla shiso seeds grow into substantial plants with wide, deep purple leaves. The dark ruby leaves of this sharply flavoured Asian herb have nicely frilled edges. They look a little bit like stinging nettle leaves, but rounder, and without any prickles. Grow as a bright-red micro-green, or let the plants mature and enjoy the leaves in pho, salad rolls, or other dishes. Shiso makes a wonderful pairing with unctuous dishes like sushi, and it combines beautifully with cilantro, mint, Thai basil and fresh lettuce leaves. Shiso has a very similar growing season to basil, and performs just as well in containers as in the garden bed. Provide full sun and well drained soil.

Timing
Timing
Start indoors in early spring, a couple of weeks after the last frost date, or direct sow outdoors in late spring, once night time temperatures are steadily above 8°C (45°F).
Starting
Starting
If starting indoors, use equal parts sterilized seed starting mix to perlite. Mix well and add to seed trays with domes. Use bottom heat from a Seedling Heat Mat to maintain a soil temperature of 20°C (70°F). Seeds should germinate in 7 to 14 days. Be careful not to over-water, particularly once seeds have germinated, as the seedlings are prone to damping off. Remove the dome at germination, but maintain bottom heat until seedlings are large enough to pot on into larger containers.
Alternatively, direct sow outdoors into well-drained garden soil. Seeds should germinate in 14 to 20 days.
Growing
Growing
Shiso does best in full sun to partial shade, in fertile, well-drained soil. Allow transplants to become established, and then grow as you would basil — pinch growing tips regularly to produce bushier plants with more leaves. Water regularly, more so in hot weather. If growing in containers, mix equal parts potting soil and composted fine bark. Orchid bark works well.
Harvest
Harvest
Pick leaves as needed throughout the summer, and harvest the flowering tops in late summer. As autumn approaches, harvest the seeds for planting next spring.

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.
