Propagation of Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve
Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve is a herbaceous flowering plant native to North America. It is commonly known as Hornemann's willowherb or milkflower willowherb. This plant is an attractive addition to any garden due to its small stature and delicate flowers.
Propagation by Seed
The easiest method of propagating Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve is through the use of seeds. Here are the steps to follow:
- Collect the seeds from the plant when the seedpods have turned brown and are starting to split open.
- Spread the seeds out on a paper towel to dry for a few days and then store them in an airtight container in a cool, dry place until ready to use.
- In the fall, or early winter, plant the seeds in a well-draining potting mix in a seed tray approximately 3mm deep. Cover the tray with plastic wrap to help retain moisture.
- Place the tray in a bright location, but out of direct sunlight, and keep the soil moist.
- The seeds should germinate within 10-15 days. Once the seedlings have reached the two-leaf stage, they can be transplanted into individual pots or into a garden bed.
Propagation by Division
Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve can also be propagated through division.
- To do this, dig up a clump of the plant in early spring or the fall.
- Carefully separate the clumps into smaller sections, making sure each section has some roots attached.
- Replant the divisions in well-draining soil, water them in and keep the soil moist until established.

Disease Management
Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve is generally a disease resistant plant. However, it may occasionally suffer from bacterial and fungal infections. These infections primarily appear on the leaves.
Bacterial Blight: This is a common bacterial disease that affects Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve. It appears as water-soaked lesions on the leaves, which later turn brown. The best way to manage this disease is to apply copper-based fungicides to the affected areas. In severe cases, pruning may be necessary to remove the infected parts of the plant.
Fungal Leaf Spot: This is another common disease that affects Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve. It occurs as circular spots on the leaves, which eventually turn brown and fall off. Fungal spores that thrive in damp environments cause this disease. The best way to manage this disease is to remove and dispose of infected leaves and keep the plant dry as much as possible. Fungicides containing neem oil can help manage the disease.
Pest Management
Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve is generally not prone to pest infestations, but it may suffer from occasional attacks.
Spider Mites: Spider mites are common pests that attack Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve. They appear as webbing on the leaves and cause the plant to look dull and unhealthy. The best way to manage spider mites is to spray the plant with water to dislodge and remove them. Application of insecticidal soap or neem oil can also help control their population.
Slugs and Snails: Slugs and snails can also damage Epilobium hornemannii Reichenb. var. lactiflorum (Hausskn.) D. Löve. They eat the leaves, leaving behind holes and chewed edges. The best way to manage slugs and snails is to remove any hiding places near the plant and keep the surrounding area free of debris. Additionally, beer traps and copper barriers can help control their population.
