Swamp mallow and its hybrids have been sought after plants for the past few years now. They are perennials with sturdy stems that have large, tropically looking flowers.Description of the plant:
CAROUSEL® is an attractive series of several swamp mallow cultivars bred by Alain Tan of French Montauban. Géant Red bears large flowers - 15-18 cm across - of deep red colour and come out from midsummer atop well-branched, strong stems reaching about one meter and forming a dense shrub. Deciduous leaves are dark burgundy red, deeply lobed and acuminate. The plant is dependent on regular water and feed supply. Use fertilizers with enough phosphorus for abundant flowering, or any other quick-release fertilizers where nitrogen is not predominant. Any fertilizing has to stop by end September.
For healthy growth and profuse flowering it needs a sunny location with a lot of moisture which can be achieved by good mulching. The soil has to be fertile and permeable, never let it dry out in summer. Hardiness has not been tested under all possible conditions but is expected to reach at least -27°C (USDA zone 5b). Cut back the plant only a few centimetres above ground level in spring.
