Description
Hibiscus 'Flower Tower Ruby' is a statuesque beauty with an unmistakable air of the tropics, yet perfectly suited to a sunny British border. Its sumptuous pinkish-red blooms, each centred with a dramatic blood-red eye, unfurl generously through the warmest months, bringing a vivid, exotic glow to the garden. Unlike the more rounded forms of traditional hibiscus, tree mallow 'Flower Tower Ruby' rises proudly upwards, its slender, pyramidal habit creating a striking vertical accent in beds, borders or large containers. Even as a young, two-year-old plant, it reaches around a metre high, hinting at the grandeur to come.
As it matures, Hibiscus 'Flower Tower Ruby' continues its elegant ascent to an impressive 3m, yet keeps a graceful, narrow silhouette of around 80cm wide—ideal for smaller gardens craving height and structure without bulk. Its glossy green leaves frame the flamboyant blooms beautifully, adding lush texture and depth. Whether used as a single architectural feature, a pair flanking a path, or as part of a mixed planting with ornamental grasses and late-summer perennials, Hibiscus 'Flower Tower Ruby' brings an irresistible touch of the exotic that never overwhelms. This is hibiscus reimagined for modern gardens—sophisticated, sculptural, and splendidly showy.

Useful information
-
Soak the Hibiscus 'Flower Tower Ruby' 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.
