Lamb’s Ear (Rose Campion, Artemisia) – Diseased

Q: We went out of town for a few days and returned to find several of my lamb’s ears, rose campion, and artemesia severely afflicted! Is it a fungus?

A: Yes, it’s a fungus and it’s all a result of regular rainfall and high humidity. Plants with fuzzy leaves or dense foliage hold lots of moisture for extended periods, leading to disease. I suppose you could prevent it with a fungicide but that presumes you can predict the weather.

When things dry out, the plants will recover.
