Front of house is lined with azaleas and hellebores next to the foundation. Landscaper mowed hellebores down. Will they return in the spring?
There are about 15 different species of Hellebores.
Most of the common plants produce leaves on one stem and flowers on another.
Cutting the leaves back should have no effect on the flowering.
If they were of the Christmas Rose species, you will likely have no flowers during this bloom period, (Dec. thru about Feb).
This variety has leaf stems and a flower stem that also has a leaf.
I generally recommend you not cut this variety back.
I do think your plants will come back in time.
