Unpack bare roots or rhizomes on arrival and plant them within a week. Until then, keep them somewhere cool and ensure the roots remain slightly moist, never wet.

Hibiscus
'Flower Tower Ruby'
tree mallow
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.

Plant calendar
Remove the packaging straight away, check the compost and water thoroughly if dry. Check the plant’s hardiness before placing it outdoors. Plant into a border or permanent container within a month, choosing the position recommended for the variety. Keep the top of the root ball level with the surrounding soil, firm gently and water well.
Soak the roots in water for three to six hours immediately before planting. Keep any crown, buds or emerging shoots above the water where possible.
Pot most bare roots into 15–20cm pots filled with peat-free multipurpose compost. Large or depth-sensitive roots, including peonies, are often best planted directly into borders.
Arrange the roots naturally without bending them. Cover the roots completely, positioning the crown and buds at the depth recommended for that particular perennial.
Keep pots in a sheltered outdoor position and water whenever the compost begins to dry. Grow on until roots hold the compost together when lifted from the pot.
Plant into a suitable border or permanent container once well rooted. Add a label and water regularly throughout the first growing season while the perennial establishes.
