A bushy shrub with prettily lobed leaves, Hibiscus syriacus Oiseau Bleu has the most wonderful deep blue/purple petals, unfurling to reveal deep cherry markings and a white eye. Because it is late flowering, it creates a wonderful display when other plants are starting to fade. A recipient of the RHS AGM (Award of Garden Merit), for all round excellence in the garden.


In their native Asia and Pacific Islands, the exotic, trumpet-shaped flowers of hibiscus entice hummingbirds to collect pollen, but flowering in a sunny border here, they are a late summer treat for bees and other pollinating insects.
