Polygala myrtifolia: A Beautiful Indigenous Shrub for South African Gardens
Trade And Home Solutions Pty Ltd | Complete Garden Solutions
Polygala myrtifolia, commonly known as the September Bush, Augustusbossie or Myrtle-leaf Milkwort, is a versatile indigenous South African shrub that brings colour, texture and natural beauty to residential gardens. Its attractive mauve, purple, pink or occasionally white flowers appear mainly in spring, with additional flowering throughout the year.
For homeowners looking to create a colourful, water-wise and wildlife-friendly garden, Polygala is an excellent choice.
Appearance and Growth
Polygala myrtifolia is an evergreen shrub with slender branches and neat, oval leaves resembling those of the myrtle plant. Depending on the growing conditions and variety, it typically reaches around 1–2 metres in height and spread, although some plants can grow larger.
Its delicate, sweet-pea-like flowers provide seasonal colour against the fresh green foliage. The flowers also attract beneficial pollinators, including carpenter bees, making this indigenous shrub a valuable addition to a biodiversity-friendly garden.
Ideal Growing Conditions
Naturally occurring from the Western Cape to KwaZulu-Natal, Polygala grows in a variety of environments, including coastal dunes, rocky slopes, forest margins and open grassland. Its adaptability makes it suitable for many South African gardens.
Growing tips:
Sunlight: Prefers full sun for the best flowering, but tolerates light shade.
Soil: Adapts to different soil types, provided drainage is reasonable.
Watering: Water regularly while establishing. Once established, it can tolerate relatively dry conditions.
Climate: Suitable for many winter- and summer-rainfall regions, including Johannesburg, although performance depends on local conditions and frost exposure.
Maintenance: Responds well to light pruning to maintain a compact, attractive shape.
Landscaping Uses
Polygala myrtifolia is ideal for indigenous garden designs, informal hedges, mixed shrub borders and colourful planting schemes. Its upright growth makes it useful beside pathways, along boundaries and in smaller garden spaces.
It can also soften walls, paved areas and hard landscaping with its foliage and flowers. Plant it in groups for a more impressive display, or combine it with other indigenous shrubs and flowering plants for year-round garden interest.
Prune lightly after the main spring flowering period, or in autumn where appropriate, to maintain its shape without unnecessarily removing developing flower buds. Avoid cutting it back too severely.
An Indigenous Plant Worth Growing
Polygala myrtifolia combines attractive flowers, evergreen foliage, adaptability and value for pollinators. With suitable positioning and basic maintenance, it can provide long-lasting colour while supporting local biodiversity.
