Hibiscus acetosella Mahogany Splendor seeds

Hibiscus 'Mahogany Splendor' is exceptionally ornamental due to its deeply dissected foliage, whose deep purple to brownish colour evolves with the light. Within just a few weeks, this tropical perennial transforms flower beds, borders, and other planters. Its foliage, reminiscent of a purple maple, creates a sensation in contemporary or exotic compositions. This hibiscus is widely used in landscaping as an accent plant. It can be overwintered similarly to citrus trees.

Hibiscus 'Mahogany Splendor' is a cultivar selected in 2012 by PanAmerican Seeds for its deeply cut and remarkably coloured foliage. Belonging to the Malvaceae family, this plant is also commonly known as "purple hibiscus" or "red-leaf hibiscus". Native to tropical regions of Africa, particularly Angola, Sudan, and East Africa, the species Hibiscus acetosella is theoretically perennial. It is believed to have originated from hybridisation between Hibiscus asper and H. surattensis, two species often grown together. It is found in moist savannas and forest clearings. Its hardiness is around -8°C at peak (for the crown) in very well-drained, even dry soil. It is typically grown as an annual due to its sensitivity to frost.

Hibiscus acetosella 'Mahogany Splendor' has an upright, bushy habit, reaching a height between 90 cm and 1.50 m with a spread of 60 to 90 cm in a single season. In the ground in mild climates, it can form a true small bush up to 2 m tall. If not pinched or pruned in spring, the plant will develop a dominant stem, but with one or two prunings, it will take on an oval, upright form and maintain more harmonious proportions. The alternate, deeply palmate and finely lobed leaves have a smooth and supple texture. In a greenhouse, they display green to rust tones. Outdoors, in full sun, they take on a very dark burgundy colour, sometimes with reddish highlights depending on exposure. These leaves measure between 15 and 25 cm long, featuring acute, deeply cut lobes. The foliage retains its beautiful colour throughout the season, then disappears with the onset of cold. The sturdy and cylindrical stems are frequently streaked with dark red.
The flowering is infrequent in temperate climates: it occurs late in the season (from October onwards) and will be absent if the summer is short. When conditions are favourable, this variety produces solitary, funnel-shaped flowers, measuring about 5 to 7 cm in diameter, coloured purple to dark red, with a darker centre. The flowers are ephemeral but renew themselves for 5 to 7 weeks. Pollination is carried out by bees and other pollinating insects. The root system of this hibiscus is a taproot, adapted for deep rooting, which gives the plant some drought tolerance in the ground.

Hibiscus acetosella 'Mahogany Splendor' is as decorative as a Japanese maple with purple leaves, adding an incredibly exotic note to summer compositions. It can be used as a backdrop in a tropical-inspired setting or as an accent in a flower bed. It pairs well with anise-green foliage, the large smoke-pink panicles and purple foliage of Pennisetum advena ‘Rubrum’, the silver foliage of Artemisia ludoviciana ‘Valerie Finnis’, or the small pink flowers of Laurentia or Isotoma 'Stella Pink'. Train a few young plants of Morning Glory 'La Vie en Rose' through its purple foliage and plant it next to a Plumbago auriculata for a guaranteed spectacle! Placed in a pot on a sunny terrace or integrated into a contemporary garden, it plays the soloist or the charming partner, depending on the gardener's mood.

In Africa, Hibiscus acetosella is used for its tangy young leaves, sometimes eaten raw or cooked, particularly in sauces or as a leaf vegetable. They retain their colour when cooked.
