This unique hybrid sunflower was bred for the florist market. It has very uniform shape and size with big flat discs and evenly radiating, bright yellow petals on strong stems for excellent cut flowers. The flowers produce nectar that is attractive to bees and other pollinators, but no pollen is produced. That means no mess beneath a vase of cut flowers. Jerusalem Gold Organic sunflowers also produce good sized black seeds. The plants are about 1.6 meters (5.5β²) tall with (usually) only one flower each. Plant Jerusalem Gold Organic sunflower seeds to attract pollinators to your organic vegetable garden, and then leave the seeds on the plants for chickadees and other wild birds to forage on.

Timing
Timing
Direct sowΒ repeatedly after the last frost date. Starting indoors is possible, but does not gain much time. If sunflowers are allowed to get root-bound, they will lack stability at transplant time, and will require staking. Optimal soil temperature for germination:Β 21-30Β°C (70-85Β°F). Seeds should sprout in 10-14 days.
Starting
Starting
Sow seeds 5mm-1cmΒ (ΒΌ-Β½β) deep. Space dwarf varieties 15cm (6β³) apart, but give the giants lots of room at 1m (3β²) between plants.
Growing
Growing
ToΒ grow really big plants with really big flowers, enrich the soil with organic matter and incorporate 2 cups ofΒ balancedΒ organic fertilizer per 3m (10β²) of row, and irrigate regularly. When the plants are 30cm (12) tall, dissolve 5ml (1 tsp) of borax (for boron) in 350 ml (12 fl oz) of water and spread the solution over 5m (15β²) of row. Be careful not to over-apply this solution. This application of boron will produce bigger seeds and flower heads. Do not apply boron to other garden plants. When the back of the flower head turns yellow, it is ready to be cut from the plant.
Companion Planting
Companion Planting
Sunflowers planted near rows of corn are said to increase yields. Sunflowers can be used to draw heavy metals, toxins, and even radiation from soil, but should be burned at the end of the season if grown for this purpose. Plant sunflowers amid squash plantings to improve pollination and overall production.

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.
Weβre 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 donβt 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 weβve learned with others.
Gardens donβt 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 β 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 earthβs stewards, planting seeds of creative declaration. The soil provides the canvas, we provide the seeds.
