Muraltia spinosa aka Muraltia Spinosa

Taxonomy ID: 3662

Muraltia spinosa, commonly known as tortoise berry (Afrikaans: skilpadbessie, duinebessie), is a much-branched, stiffly erect, rounded shrub native to South Africa. It typically reaches about 1 metre in height and spread, with arching, spine-tipped stems clothed in small, narrow, deciduous leaves. The plant belongs to the milkwort family (Polygalaceae) and was long classified under the genus Nylandtia before molecular studies relocated it to Muraltia in 2006.

The flowers are sweetpea-like in appearance, produced in purple, pink, or white, and are borne from autumn through early spring (April to October). Fleshy, bright red fruits follow throughout summer; these are edible, rich in vitamin C, and described as thirst-quenching. Tortoises and birds consume the fruits and disperse the seeds, giving rise to the plant's common name.

In the wild, Muraltia spinosa grows on sandy flats and rocky slopes from Namaqualand through the Western Cape and along the Eastern Cape coast, inhabiting the Fynbos, Succulent Karoo, and Savanna biomes. It is a South African endemic with a stable population and is assessed as Least Concern on the SANBI Red List.

The plant is well suited to water-wise and coastal gardens. It tolerates frost, drought, and wind once established, and is considered easy to grow in full sun with well-drained, sandy to loamy, acid to neutral soil. Moderate growth rate; light pruning encourages a bushy habit. Propagation is best achieved from fresh seed, which germinates in approximately two to three weeks.

Traditionally, the plant has been used medicinally: fermented leaves in small amounts are said to aid sleeplessness; a stem or leaf tea is used for abdominal pain, tuberculosis, and as a bitter digestive tonic; when combined with Lebeckia multiflora, the preparation is used for colds, flu, and bronchitis; and Tswana healers use the roots to treat malaria. The plant also attracts honeybees and birds, and can be used to stabilize coastal sand dunes.

The flowers are sweetpea-like with three to five petals in purple, pink, or white, and are produced from autumn through early spring (April–October). The lower petals form a boat-shaped structure with seven fused stamens, characteristic of the Polygalaceae family.

Are there varieties of Muraltia spinosa?

Muraltia spinosa belongs to the genus Muraltia, which contains 119 accepted species. It was formerly placed in the genus Nylandtia (as Nylandtia spinosa) before molecular studies in 2006 moved it to Muraltia. It shares the "tortoise berry" common name with the closely related Muraltia scoparia.

Can Muraltia spinosa be grown outdoors?

Muraltia spinosa is exclusively an outdoor plant suited to warm, sunny positions. It performs well in rockeries, on slopes and embankments, in mixed shrub borders, fynbos gardens, and coastal gardens. It is wind and drought resistant once established and can be used to stabilize coastal sand.

How should Muraltia spinosa be pruned?

Light, regular pruning encourages a bushy habit. No heavy pruning is necessary; the plant requires no special treatment beyond removing straggling growth.

How is Muraltia spinosa propagated?

Propagation is best achieved from fresh seed. Remove the fleshy covering from seeds and sow in spring or early summer in well-drained soil; germination typically occurs within two to three weeks. Cuttings are slow and difficult to root and are not the preferred method.
