Alcea rosea. Sow Indian Spring hollyhocks seeds in full sun. This is a selection of our most popular Hollyhocks seeds, blended for planting en masse to create a beautiful cottage garden. Tall spires grow to 2m (6') or more, with single, double, and ruffled flowers that fill in empty garden spaces with blooms in rose, pink, white, chocolate, purple, and lavender. This blend looks sensational from late spring to frost. Hollyhocks are both tall and drought tolerant, so they are a nice choice for xeriscaping. Avoid overhead watering with hollyhocks in order to delay foliar diseases, including rust and powdery mildew. These are not uncommon problems for hollyhocks, but rarely make much impact.

Timing
Timing
Start hollyhocks 6-8 weeks before planting out after the last frost date. In mild winter areas, start seeds indoors in late February to early March, and transplant out in April or May. An early start usually results in flowering the first year. Seeds germinate in 10-14 days. Ideal soil temperature for germination: 15-21°C (60-70°F).
Starting
Starting
Sow seeds on the surface of the soil, and provide bright light. Use peat or coir pots in an effort to minimize root disturbance. Transplant at 45-60cm (18-36″) apart.
Growing
Growing
Grow in rich, moist soil with good drainage and a neutral pH range of 6.0-7.5. The most important factor is good air circulation, so do not crowd plants or plant too close to structures, hedges, etc… Keep well watered and feed a few times during the growing season. If the flower stalk is cut back immediately after finishing, plants may bloom again. Stake tall plants.
Rust is a leaf disease to which hollyhocks are especially prone. It is worse on older plants and can be kept in check by replacing plants every couple of years.
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.
