Hibiscus syriacus Ultramarine br

Also known as the tree Hollyhock or the Rose Mallow, Hibiscus syriacus 'Ultramarine' is covered in large, purple-blue blooms from July - not stopping until all buds have opened, sometimes right into September. 'Ultramarine' is a medium-sized, deciduous shrub with strongly lobed, dark green leaves and blush-purple flowers up to 9cm (3.5in) in width, each with a bright maroon blotch at the base of every petal. The flowers shimmer faintly with iridescence in the sun, making this a garden plant that everyone will comment on. Despite its exotic looks, Ultramarine is very tough, winter hardy and easy to care for, and is best placed in a prominent position, where it will bring a colourful display when other plants are beginning to look tired. Supplied as a dormant bare root plant ready for immediate planting, 'Ultramarine will reach approx. 2m x 1.5m (6 ft x 5 ft).
