Providing late season colour, Hibiscus syriacus ' Oiseau Bleu' has large lavender-blue flowers, with maroon & cream centres, from August until October. It is a nice addition to wide garden borders in sunny locations, especially in gardens where most of the shrubs flower earlier in the year, such as Rhododendrons. This beautiful Rose Mallow has been awarded an RHS AGM for its outstanding garden performance.
