About Common milkwort
Polygala vulgaris, commonly known as Common Milkwort or "storblåfjær" in Norwegian, is a small perennial herbaceous plant belonging to the Polygalaceae family. It is characterized by its delicate blue, pink, or white flowers arranged in terminal spikes. It is ideal for rockeries, naturalistic gardens, or as part of a wildflower meadow, where its modest beauty can be appreciated.
Native range
Europe and temperate Asia
Care tips
It prefers full sun to light partial shade and well-drained soil, preferably calcareous or neutral. Watering should be moderate, allowing the substrate to dry slightly between waterings, as it does not tolerate waterlogging. Avoid very acidic and heavy soils, which can lead to root rot. A common mistake is planting it in deep shade, which will result in sparse flowering.
