Helianthemum General Information

Sun Roses, evergreen subshrubs, are extremely drought tolerant once established. Vivid colored flowers will blanket the low mound of wiry stems. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Helianthemum Plant Care

Plants must have good winter drainage. Best grown in dry, alkaline, sandy well-drained soil in full sun. Shear lightly immediately after flowering to shape and encourage additional growth and possible rebloom.

Plantable Pots

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!

100% Guarantee

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!
