May Politely Self Sow
Like sails in a summer breeze, purple bell-shaped nodding flowers are hoisted above the petite 8” foliage mounds on 1’ slender stems. May politely self-sow to naturalize. Campanula Collina forms compact, bushy mounds suited for border edges and rock gardens. Best in part shade in hot summer climates and full sun in cool northern areas. Due to its mounding habit, this charmer is named Collina which refers to an area of land that is higher than the land that surrounds it, but not as high as a mountain.

Campanula General Information

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

Depending on the summer and the site, Campanula may benefit from cutting back in the summer to freshen it and keep it blooming. This is best handled in stages by cutting back half of the plant by a third and allowing the rest of the plant to continue. Once the cut section improves, cut back the other section. This will keep the plant in bloom for a majority of the season. Plants will benefit from being divided every 3-4 years in spring or fall.

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!
