'Multi Blue' is a hardy deciduous climber to 1.5-3.5m tall with bronze young leaves, maturing to mid-green. Blue flowers, 8-13cm across, are borne from early summer to early autumn. The central tepals gradually expand as the flower matures, revealing a fully double flower; flowers become paler and more silvery with age.
Plant in moist but free-draining soil with roots in the shade. Plant with the crown 10cm below soil level. Likes full sun or partial shade
