Description
Hibiscus 'Flower Tower Purple' is a showstopper from bud to bloom, offering an irresistible fusion of elegance and energy. Each flower is a painterly marvel—soft purplish pink petals blending into a rich purple-red throat that feathers outward like watercolour on silk. This bicoloured brilliance glows against the plant’s glossy green foliage, creating a mesmerising display that continues faithfully throughout the late summer months. Even in its early years, a container-grown Hibiscus 'Flower Tower Purple' plant rises to around a metre high, already hinting at its striking upright habit and sculptural poise.
Unlike the traditional rounded forms of old-fashioned hibiscus, Hibiscus 'Flower Tower Purple' grows with bold vertical intent, maturing into a graceful pyramid reaching around 3m high yet just 80cm wide. Its tall, slim shape is ideal for adding height and drama where space is limited—perfect for narrow borders, courtyards, or as a centrepiece among low perennials and ornamental grasses. Tree mallow 'Flower Tower Purple' combines modern breeding with timeless beauty, offering the exotic charm of the tropics with the practicality and refinement of a British garden favourite.
'Flower Tower' hibiscus are sterile—since they produce no seed, all their energy goes straight into a spectacular, extended flowering season.

Useful information
-
Soak the Hibiscus 'Flower Tower Purple' roots in water for 3-6 hours prior to planting
Plant your "Tree mallow" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
