Eryngium General Information

Eryngium are thistle-like flowers that blanket spiny foliage. Flowers dry beautifully adding texture to bouquets, borders or containers. Great for cut flowers too. Blooms hold their color while lateral flowers develop, until the entire stem is covered with mature blossoms. All are hardy, long-lived, salt and drought tolerant. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Eryngium Plant Care

Loves a sandy, well-drained site. Will tolerate drought and neglect in hot dry spells. Cut down flower stems to prevent seeding or let it fill in a difficult spot. A long taproot makes it difficult to move or divide this plant, but can be done in spring if necessary. Plants will be slow to recover.

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!
