CLEMATIS ‘Perle d’Azur’
Sumptuous, bee-friendly BLUE flowers of this perennial climber shared pergola and rose arch with Morning Glories here for years. ‘Perle d’Azur’ is generous with its flowers, which bloom from June to late Autumn.
Its leaves may suffer from powdery mildew by September, but the flowers remain perfect. Spray with dilute washing-up liquid, but nothing more lethal than that. After flowering, cut back to young sideshoots or strong buds lower down.
Penelope Hobhouse grew ‘Perle d’ Azur’ in the garden at Tintinhull, Gloucester, where she underplanted it with Cranesbills – Hardy Geranium x oxonianum ‘Wargrave Pink’.
