Hellebores are long living plants they go on for years providing the conditions are right. Mine are grown in the garden dotted around in sun and shade. I cut the tatty leaves off.
Before the flowers come I cut off all the leaves. I will cut off all flower stems when finished flowering. If you want more you can leave a couple on to self seed. It may be white or pink. Hellebores are so promiscuous.You never know what colour the seedlings will be. This one is probably purple.
