The Pyramidal Bellflower is a striking perennial or biennial, known for its impressive height and abundant, showy flowers.

The plant produces masses of star-shaped, bell-like flowers in shades of pale blue. The flowers are densely packed along tall, upright flower spikes, creating a pyramid effect and giving the plant its name.

One of the tallest Campanula species, reaching heights of 90–180 cm (3–6 ft) or more under optimal conditions.

Usually grown as a biennial cut flower.
