Hellebore Leaves Are All Yellow
I live in Seattle. My Hellebores are planted in loamy soil, and in part shady area. These plants have been in this location for about 4 years. All the leaves have turned yellow, one even almost white. Any ideas on what could be the issue?

Is there some type of conifer dropping needles onto the area? This could be the issue. When these break down into the soil, it becomes quite acidic. Many plants cannot handle this.
Since they don't normally experience many deficiencies, anything that appears as one will likely be a pH imbalance.
You may look to moving them, or trying to amend the soil. Taking the soil's pH will be a good start: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/soil-ph-plants.htm
