Ratibida columnifera. Plant this perennial wildflower in your organic flower garden, or grow it in containers. Ratibida Prairie Coneflower seeds are useful for water-wise xeriscaping plans because the plants are native to the central prairies and mountains, and accustomed to drought, high heat, and high humidity. The central cone of each flower is surrounded by lovely bright red petals tipped in fiery sun-bright yellow. The strap-like leaves are bluish green and form a rosette. Avoid getting the leaves wet (or water only first thing in the morning) to prevent the onset of foliar disorders like powdery mildew. Flowers appear from late spring to autumn, and stems can range from 60-150cm (24-60") tall.

Timing
Timing
Start transplants in a cold frame in early spring, or direct sow in May to June. Starting indoors requires vernalization – wrap planted pots in plastic and store in the refrigerator for one week, and then provide 20°-24°C (68°-75°F). Do this step 4-6 weeks before planting out. Seeds will germinate in 7-42 days.
Starting
Starting
Barely cover the seeds with soil. Transplant or thin to stand 30-60cm (12-24″) apart.
Growing
Growing
Stake tall growing plants in windy gardens. Ordinary, well-drained soil will do. Ratibida is susceptible to foliar diseases like powdery and downy mildew, fungal spots, and leaf smut. To avoid these, mulch around the plants and only water in the morning, avoiding getting the leaves wet. These plants are highly resistant to heat and humidity, and they are suitable for xeriscaping.
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.
