Astilbe General Information

Astilbe lend a refined grace to perennial borders. Perfect for the shade garden along with Hostas and Ferns. Lush deeply cut foliage is attractive for the entire season and is colored from green to bronze. Effective anywhere with rich moist soil and partial shade.

Astilbe Plant Care

Low care. Needs moisture during dry spells. Dried heads can be left standing if desired or cut down at anytime. Can be divided every 3-5 years in early spring. Cut through woody crowns to separate eyes to form additional plants. Add fertilizer or compost if desired when planting or moving and in late fall to winter.

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!
