Echinops General Information

Echinops are not thistles despite their common name, Globe Thistle. Provides carefree late summer color. Does well in any soil. Provides good color and contrast in the perennial border, especially toward the back, or in the cut flower garden. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Echinops Plant Care

Deadhead initial blooms and several smaller shorter blooms will appear. Once done blooming, cut all flower stalks to the basal foliage and leave to overwinter. Clean up in spring. These plants are slow to recover after being moved or divided. Can be divided in early spring by carefully splitting a few offsets from the base of an established clump.

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!
