Helianthus add structure to the summer border. Performs from late summer into October when other perennials rest. Plants are carefree in full sun. Finches flock to the dry seed heads.
Idaho has restricted all potted plant material from being shipped into Idaho
at this time.
Prefers average, neutral to slightly alkaline soil. Well-drained soil is good for overwintering, but give Helianthus a good soaking if August begins to overpower. Can be divided in spring every 3-4 years.
Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
We offer a 100% unconditional guarantee for all our perennials to reach you in good condition and to grow. If you're not satisfied, we'll reship or refund immediately. Please don't hesitate to contact us if you have questions or concerns—we share your passion for gardening and want your new plants to thrive in your border!
We use custom, earth-friendly packaging to make sure your order arrives in great condition, and we ship based on the best planting time for your growing zone (see the approximate dates below), unless otherwise indicated at checkout. If you wish, you can indicate a specific ship date during checkout.
