Like 'Brookside' but with darker blue flowers, 5cm across. The stuff of myth! Average soil in sun, 70cm. Summer with good repeat and super foliage colour in autumn.
Masses of small blue flowers in spring. Alan Bremner's hybrid: a compact clump of leaves and the myriad of flowers are held erect for weeks in late spring. Open or light shade, not too dry. 70cm.
