'Carousel Geant Red'
rose mallow
Hibiscus 'Carousel Geant Red' doesn’t do subtle—it’s all drama, glamour and tropical flair, right here in a temperate garden. This hardy rose mallow from the Carousel Series boasts deeply cut, dark green foliage that forms a dense, bushy clump, providing a perfect stage for its magnificent flowers. And what flowers they are—rich, velvety red blooms up to an astonishing 18cm across, unfurling like silken fans through the height of summer. Each blossom looks as though it belongs in an exotic paradise, yet Hibiscus 'Carousel Geant Red' is perfectly content in an ordinary UK border or large patio pot.
Low-maintenance, long-flowering and surprisingly tough, Hibiscus moscheutos 'Carousel Geant Red' keeps up its spectacular display from mid-summer into early autumn, its blooms popping against the moody backdrop of dark, glossy leaves. It’s happiest in full sun and a spot sheltered from strong wind—after all, even showstoppers appreciate a bit of protection. A true performer, Hibiscus 'Carousel Geant Red' brings warmth and theatre to any setting without demanding constant attention. If you’ve ever dreamt of tropical borders but lack the climate to match, this exuberant red rose mallow is your chance to cheat the weather with style—and a healthy dash of red-hot attitude.

Plant profile
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.
