About Broad-leaved willowherb
Epilobium montanum, commonly known as Broad-leaved Willowherb or 'krattmjølke' in Norway, is a perennial herbaceous plant belonging to the Onagraceae family. It is characterized by its erect stems, opposite or alternate leaves, and small, pale pink to purplish flowers. It is ideal for wild-style gardens, roadside borders, or as part of a wildflower meadow, adding a natural and delicate touch.
Native range
Europe and temperate Asia
Care tips
It prefers locations with partial shade or partial sun, though it can tolerate full sun if the soil is kept moist. Regular watering is required to keep the substrate consistently moist, especially during dry periods, but avoid waterlogging. It adapts well to moist, well-drained soils rich in organic matter. A common mistake to avoid is letting the soil dry out completely, which can stress the plant and reduce its flowering.
