Birch Hybrid Bellflower is a short, spreading perennial also know as Dalmatian Bellflower, Wall Bellflower, Wall Harebell and Adria Bellflower. The trailing foliage is dark green, heart shaped, and has sharply toothed margins. From late spring to early fall, this perennial produces an abundance of delicate, bell shaped, violet purple to lavender blue-coloured flowers that cover the whole plant.
This plant is an excellent ground-cover or border species when planted in mass groupings. Campanula portenschlagiana 'Birch Hybrid' looks perfect spilling out of a container, cascading over a wall, or rambling throughout a rock garden.
Birch Hybrid has one of the longest blooming periods of any Campanula. Remove spent flowers to encourage more new blooms. This plant is easy to grow in a range of conditions, and behaves less aggressively than other Campanula varieties.
Some sources indicate 'Birch Hybrid' being a cross between C. poscharskyana x C. garganica, rather than a new variety of Campanula portenschlagiana.
