Firework like spires of flower burst into life during the summer. Deep, rich blue flowers with exerted stamens cluster around slender stems. The green lance-shaped leaves have slightly serrated margins.
'Marietta' has a compact habit and is regularly used towards the front of beds and borders. This plant is often planted in boggy situations as V.longifolia can cope with very moist soils 'Marietta' can conversely, cope fantastically well with dry situations. Sun or part-shade positions are desirable. Cut back the stems after the blooms have gone over, to encourage further flowering down the stem.
