Summary

Polygala myrtifolia, commonly known as Myrtle-Leaf Milkwort, is an evergreen shrub native to the coastal regions, forest margins, and scrublands of Southern Africa. It typically grows to a height of 5-6 feet and a width of 4-6 feet. The plant has a dense, rounded form with leathery, myrtle-like leaves that are a glossy green. The showy flowers, resembling those of sweet peas, bloom in shades of mauve, pink, crimson, or white, and feature a distinctive brush-like tuft. These blooms are present for much of the year, peaking in spring and summer. The fruit is an oval, brown, narrowly winged capsule that splits open when ripe.

Myrtle-Leaf Milkwort is valued for its long flowering season and its ability to attract pollinators with its unique flowers. It is used in gardens for hedging, as a screen, or as a feature plant in mixed borders. This species is drought-tolerant, making it suitable for xeriscaping and low-water landscapes. It requires well-drained soil and thrives in full sun to part shade. While generally low-maintenance, it can be susceptible to root rot if overwatered. In regions where it is not native, such as California, it can become invasive, so gardeners should consult local guidelines before planting.CC BY-SA 4.0
