Answer: What you describe sounds like crown rot, brought on by overly moist (poorly draining) soil. Brunnera like moisture but requires fast-draining soils. In your growing region, they prefer morning sun and afternoon shade. If you try again, use a good grade potting soil and make sure there's adequate drainage holes in the bottom of the container. Water throughly, then allow the top half-inch of soil to dry before watering again. The key is to have the potting soil damp but not soggy wet. Stick your finger down into the soil; if it is still moist 2" beneath the soil surface, you won't need to water for a day or two. If it's dry, it's time to water again. Hope this information helps you grow healthy Brunnera!
