Polygala myrtifolia Grandiflora

Common Name:
Large-Flowered Sweet Pea Shrub

Description:
Polygala myrtifolia 'Grandiflora' is a fast-growing, evergreen shrub known for its profusion of vibrant purple, pea-like flowers with delicate fringed petals. Blooming almost year-round, with peak displays in spring and summer, this hardy shrub provides long-lasting colour and interest in the garden. Its dense, dark green foliage and upright, rounded habit make it ideal for hedging, borders, and feature planting. Thriving in Melbourne’s climate, ‘Grandiflora’ prefers well-drained soil and a sunny to partly shaded position. It is drought-tolerant once established and requires minimal maintenance beyond occasional pruning to maintain its shape and encourage continuous flowering. Its nectar-rich flowers attract bees, butterflies, and birds, enhancing biodiversity in the garden.
