Calamagrostis General Information

Calamagrostis are prized for the bold vertical accent that they lend to the border. Among the earliest flowering grasses, they are very mannerly and stay attractive all winter. Thrives in clay and wet soils. Ornamental grasses are restricted in Oregon.

Calamagrostis Plant Care

Cut back in early spring to approximately 6-12" before new growth appears. Divide in spring or fall. Attractive seedheads add winter interest and provide food for the birds.

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% 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!
