Campanula General Information

Campanula glomerata does well in most soils as long as it is well-drained. Sun to part shade. Campanula are versatile perennials that provide a wide range of colors, shapes and uses. Many varieties offer long bloom time and easy care, while others feature some of the best blues and deepest purples in the perennial world. Spikes, globes, carpets-Campanula offer many pleasing forms. Idaho has restricted all potted plant material from being shipped into Idaho at this time.

Campanula Plant Care

Removing spent flowers stalks will encourage rebloom and discourage seeding (if not wanted). Leave any new fall foliage at the base to overwinter. Can divide every 3-4 years in the spring or fall. Tolerant of alkaline soils.

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!
