Milkwort Plant Info

Common milkwort is found in grasslands, heaths and dunes. It is a familiar sight in the landscape in Britain, Norway, Finland and other European countries. Polygala vulgaris is the plant’s scientific designation. The Greek polugalon means “to make much milk.” This describes the plant’s historic use as an aid to increase lactation in new mothers. There were many medicinal and religious uses for milkwort, some of which persist today.


Milkwort wildflowers are small plants, only 4 to 10 inches in height. It produces many long downy stems that spring from a basal rosette. Flowers are generally deep to light blue but may also be white, purple and pink. Flowers have tiny petals flanked by a pair of flattened sepals that resemble petals. The overall bloom resembles a pea flower with its fused keel and tubular upper petals but is not related to the family.

The slender lance-shaped leaves are alternate along the stem and disappear from the lower plant during bloom time. Common milkwort is listed as endangered in Finland due to habitat loss. In its native regions, Milkwort is found in meadows, pastures, banks, and hummocks.

Growing Milkwort Flowers

Growing milkwort flowers from seed seems to be the best method of propagation. Seeds can be hard to come by, but some online retailers do carry them. Start seeds indoors before all danger of frost has passed or sow into a prepared bed after any frost is expected.

Keep seedlings moderately moist and use a diluted plant food once seedlings have 4 sets of true leaves. Milkwort performs well in either full or partial shade in well-drained soil. These plants are best in a mass of undulating wiry stems and sky blue flowers.

Plants can be cut back in late fall to within 6 inches of the ground. Mulch around them to protect the root zone from winter’s chill.
