Bellflowers are perennials found in most of Northern hemisphere. They are popular in landscapes as well as they are maintenance-free and easy to grow. They offer several flower colours: mostly violet and white, and rarely blue and even pink, and bloom from early summer until autumn – upon variety.

Thumbell™ Blue is an improved selection of harebell with cup-shaped, violet-mauve flowers on thin stems. They come out in early June and bloom over a long period throughout summer until September. The bottom leaves are rounded to heart-shaped, and along the stems they are linear.

Thumbell™ Blue forms a bushy clump and prefers a sunny location. It can be grown under trees with thin canopies providing filtered sunlight. The soil should be evenly moist. Harebells are grown in rockeries, too, if the soil is not left too dry. Very hardy to min. -38°C (USDA zone 4), possibly a little more.
