Epilobium komarovianum, commonly known as Bronzy Willowherb, is a creeping perennial herb in the Onagraceae family. It is native to New Zealand, but has been introduced to other parts of the world including western Europe and the USA. It forms mats of tightly appressed leaves up to 1m in diameter, with individual flowers arising from the leaf axils. The flowers are white and bloom in the summer. It is an invasive species and can cause problems in areas where it has been introduced, as it can outcompete native species and alter the structure and composition of habitats.


Bronzy Willowherb (Epilobium Komarovianum) is a rare species of herbaceous plant that is native to the northern hemisphere. It is known for its unique foliage, which is bronze in color, and its delicate, bell-shaped flowers that bloom in the late summer.

Epilobium Komarovianum is a perennial plant, meaning it will grow back each year from its roots. It typically grows to be about 50 cm tall, but can reach up to 80 cm in some cases. The plant has narrow, lance-shaped leaves that are typically about 5 cm long, and its bronze coloration is a result of a dense layer of hairs on the underside of the leaves.

The flowers of Bronzy Willowherb are a soft, pale pink color and bloom in the late summer, typically in late August or early September. They are arranged in clusters at the top of the plant, and are held above the foliage on long, slender stems. The flowers are about 2.5 cm long and have four petals that form a bell shape.

Epilobium Komarovianum grows best in moist, well-drained soils, and in full sun to partial shade. It is an adaptable plant that can tolerate a range of soil types and pH levels. It is also tolerant of drought and can survive in dry conditions once established.

This rare species of willowherb is often sought after by gardeners and botanists for its unique foliage and delicate flowers.

One thing to keep in mind when growing Bronzy Willowherb is its invasiveness. While it is a hardy plant that can adapt to a range of growing conditions, it can spread quickly and become invasive in some areas. To prevent this, it is best to plant it in an area where it will be contained, such as in a rock garden or raised bed.

In terms of care and maintenance, Bronzy Willowherb is relatively low maintenance. It will benefit from occasional watering during prolonged dry spells, and may need to be cut back after flowering to maintain a neat appearance.

For division, the plant can be divided in the spring or fall, when the soil is moist. Simply dig up the clump, separate it into smaller pieces, and replant each piece in a new location. Be sure to water the newly divided plants well and keep the soil moist until they are established.

Bronzy Willowherb is also a great choice for container gardening. If you are growing the plant in a container, be sure to choose a pot that is large enough to accommodate the plant's root system, and use a high-quality potting mix that is well-drained.
