Hibiscus moscheutos Cherry Cheesecake - Swamp Rose Mallow

The 'Cherry Cheesecake' Hibiscus moscheutos is a spectacularly hardy perennial for wet terrain. From July to September, it produces huge white flowers with pink markings, reaching up to 20 cm (7.9 in) in diameter. The lush dark green foliage will bring an exotic touch to your flower beds, whether planted along a pond edge in rich compost or in a large pot kept constantly moist in full sun.

The 'Cherry Cheesecake' marsh hibiscus belongs to the Malvaceae family. While we are familiar with bushy hibiscus plants, from the same family and commonly planted in gardens, the Hibiscus moscheutos (formerly H. palustris) are more rarely encountered. This giant perennial, also known as Marsh Mallow, is native to the marshy areas of the Eastern United States and can grow stems over 2 metres (6 feet 7 inches) tall. In our gardens, it generally remains more modest and emerges quite late in spring, between April and May. Its growth is then rapid: in just a few weeks, it forms a lush clump of upright stems adorned with large lobed leaves, emerging from a thick base. From mid-summer to early autumn, huge flowers appear, with open cup-shaped blooms, large rounded and slightly crumpled petals. In the centre, a long tube formed by fused stamens adds grace to the flower. In autumn, the foliage also takes on beautiful golden colours, and then the plant disappears.

The 'Cherry Cheesecake' Hibiscus is a compact variety, forming a dense clump 1.20 to 1.50 m (3 ft 11 in to 4 ft 11 in) in height and width. Its very large flowers, appearing between July and September and reaching 20 cm (7.9 in) in diameter, are white with pale pink veins and bright pink petal margins. The flower's centre is an intense purple-pink. This variety belongs to the Summerific series, obtained by Walter Gardens nurseries in the United States, which is characterised by dark foliage, moderate size, and abundant flowering.

The 'Cherry Cheesecake' Marsh Mallow is, as the name suggests, fond of moist soils. If the soil is rich and consistently moist, the plant will show vigorous growth. In dry or poor soil, it will produce mediocre results. Additionally, it requires plenty of sun to fully express its flowering potential. Despite its exotic appearance, it is hardy and will easily withstand temperatures down to -12, even -15°C (5 °F). Undoubtedly, it is a perennial that brings a great presence to the garden, and it should be placed judiciously: combine it with other plants with an "exotic look" to create a striking scene, such as the Sikkim Banana, 'Himalaya' Arum, Tetrapanax, Rostrinucula dependens, or the tree fern Dicksonia antarctica. If your soil is not moist enough, choose to grow it in a large container, which will provide excellent results as long as the soil does not dry out - allowing you to enjoy it on your terrace!
