What is the best time to plant Brunnera?

Brunnera can be planted in early spring before other perennials have begun to grow. This will give the plant a head start on the growing season. It is best to plant Brunnera in moist, well-drained soil. The planting site should receive full sun to partial shade.

How often should you water Brunnera?

Brunnera should be watered on a weekly basis, providing the soil has dried out somewhat since the last watering. Allow the top inch or two of soil to dry out before watering again. Overly wet conditions can lead to root rot and other fungal diseases.

What type of fertilizer is best for Brunnera?

A slow-release, balanced fertilizer is the best option for Brunnera. In the early spring, when growth begins, you can apply a high-nitrogen fertilizer to promote new growth. Once growth has begun and the plant is established, switch to a low-nitrogen or slow-release fertilizer to maintain optimal health.

How do you care for Brunnera plants?

In order to care for Brunnera plants properly, it is important to monitor soil moisture levels regularly and water as needed. You should also remove any dead or wilted foliage from time to time in order to keep your plants looking healthy and vibrant. If you notice any signs of pest infestations or fungal diseases, take steps to address these issues immediately in order to prevent further damage. Additionally, you may need to trim your Brunnera plants from time to time in order to maintain their size and shape or propagate new plants using cuttings. With proper care and maintenance, your Brunnera plants should thrive for years to come!


Brunnera is a beautiful perennial that can be used in many different ways in the landscape. It’s perfect for shady areas where other plants may not thrive.
