Growing to 1 m (3.3 ft) tall by up to 50 cm (20 in) broad, it is a deciduous sub-shrub with broad downy leaves in groups of three, and delicate clusters of elongated tubular blue flowers in late spring and summer. Mature blooms recurve (bend backwards) into a trumpet shape. Repeat flowering sometimes occurs in autumn.[3]
The Latin specific epithet heracleifolia means "with leaves resembling hogweed" (Heracleum).[4]
The cultivar 'Cassandra', with fragrant flowers, has won the Royal Horticultural Society's Award of Garden Merit.[5]
