Description
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.

Useful information
-
Soak the Hibiscus 'Carousel Geant Red' roots in water for 3-6 hours prior to planting
Plant your "Rose 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.
