Polygala myrtifolia – September Bush
R79
Polygala myrtifolia, commonly known as the September Bush, is a fast-growing evergreen shrub native to South Africa, cherished for its profuse flowering and graceful form. It features slender, lance-shaped leaves that resemble those of the myrtle (hence the name "myrtifolia"), and produces vibrant purple to magenta flowers with a characteristic tufted keel, resembling pea flowers. Blooming mainly in spring and autumn, it also flowers intermittently throughout the year in mild climates. This resilient shrub is ideal for hedging, screening, or as a feature in mixed borders, bringing color, movement, and pollinator activity to the garden.
