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. Fireball is a unique variety with large, about 15-25 cm across, clear red flowers from midsummer until early autumn. The leaves are very attractive, too, they are deeply lobed, dark green with burgundy red shades.
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. Hardy to about -29°C (USDA zone 5). Cut back the plant only a few centimetres above ground level in spring.
