Delphinium consolida. Sow Rocket Larkspur delphinium seeds in fall or in early spring, when some risk of frost is still possible. Stunning spires in shades of purple and blue grow up to 1.2m (4') tall, attracting wild and domestic pollinators. Grow this southern European native in full sun or part shade, but keep soil relatively moist. This annual Delphinium produces copious seeds and will self sow from year to year. The seeds are easy to collect and share. Alternately, simply cut the seed heads down after the flowers have faded and avoid self sowing all together. Rocket Larkspur looks amazing when contrasted with yellow or orange flowers of a similar height. Try planting it near Black-Eyed Susan Rudbeckia.

Timing
Timing
Sow indoors 8-10 weeks before planting out. Or simply direct sow in early spring, when a light frost is still possible, or early autumn. Seeds take 14-28 days to sprout.
Starting
Starting
Just cover the tiny seeds. If starting indoors, vernalize seeds by planting them in trays in sterilized seed starting mix. Place these inside plastic bags and refrigerate for 2 weeks. Then place them in total darkness and maintain a soil temperature of 10-12°C (50-55°) until sprouted. Once sprouts appear, place below bright light. Space or thin to 30-45cm (12-18″) between plants.
Growing
Growing
Deep, rich, well-drained, slightly acidic soil. For the most bloom potential, water well throughout the season, and feed once in the early spring. Remove spent flowers immediately after the first bloom, and feed again. When new growth reaches about 20cm (8″) tall, cut back old growth completely.
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.
