This is an upright, regularly rounded selection, well branched from the base. The floral stems are robust and straight and carry numerous wide and brightly-coloured flowerheads. The elegantly cut ray florets are blue-purple surrounding a white disc. Flowering from the end of June, a profusion of blooms are renewed all summer. They attract butterflies. 'Mels Blue' is recommended for flowerbeds or tubs; it catches the eye from a distance.
Remove faded flowerheads to encourage the arrival of new buds.
