1. Please identify the large-leafed plants in the photo "large plants". They look the same, except the one is the foreground is about 2 feet high, and the one behind it is about 3 feet high. Photo taken June 30 in Potomac, MD.
2. Please identify the plant in the photo "serrated leaf plant." Photo taken June 30 in Potomac, MD.
3. Can you determine a likely cause or causes for the leaf browning and decay in the photo "lenten rose"? This lenten rose (and several nearby) looked healthy and bloomed in the spring, but now look pretty bad.

The large-leaved plants resemble Pokeweed, though it's hard to tell through the deer netting. It is a native perennial, but can be very hard to remove where it's not wanted, due to a deep and massive taproot on established plants.
The second plant is hard to ID through the netting as well, but somewhat resembles Lambsquarter. It's a non-native annual, and is usually easy to remove.
It's hard to tell what is damaging the Hellebore. You can look around the crown (where leaves emerge from the roots, at the soil line) for indications of a disease like Southern Blight, and if found, the plant might need to be removed. Otherwise, the spotted and browned leaves can be trimmed off, given how extensive the damage is, to help the crown get better airflow. We can't determine if it will recover, but there is no other intervention (like fungicide use) that would provide any benefit at this point, so it's a wait-and-see situation with monitoring it for other symptoms or indications of regrowth. If it rebounds but then succumbs to damage again, feel free to send us more photos for assessment.
