Lathyrus odoratus. The Spencers bloom when the heat of mid-summer arrives after a cool spring. The plants produced by Late Spencer Blend sweet pea seeds have strong stems and outstanding fragrance. The upper petals are ruffled, and the lower “wings” are longer than other varieties. All the beautiful, bold colours so loved in these reliable performers—red, pink, white, rose, purple, and blue. Be sure to pick off any spent flowers to keep the vines producing more flowers. If any seed pods form cut them off to keep the plant blooming. Combine some of the earlier flowering varieties with your Late Spencer Blend, and you'll enjoy a much longer sweet pea harvest window.

Sow indoors 6-8 weeks before the last average frost date for your area. Or direct sow outdoors in early spring, while the soil is still cool and light frost is still possible. Plants are strongest from an early, indoor sowing. Sweet peas can also be direct sown in the fall where winters are mild.
Starting
Starting
Sow seeds 1cm (½”) deep. If starting indoors, chip seeds or soak them in warm water for 24 hours. Use a seed inoculant for the best results. Maintain a soil temperature of 12-18°C (55-65°F). Seeds should germinate in 10-20 days.
Growing
Growing
For best results, prepare the sweet pea bed the previous fall. Cultivate the soil to 45cm (18″) deep, incorporating a generous amount of finished compost. Also dig in bone meal. At transplant time, dig ¼ cup balanced organic fertilizer into the soil beneath each plant. Space vines at 15cm (6″) and provide trellis support. Mulch around plants to keep the soil as cool as possible, and water during dry weather. Keep plants picked to prolong the blooming period.
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.
