Busy Lizzie, as they are very long lived - the bergenias, i mean, they probably take some time to reach flowering size (like peonies). There is a huge spread in the Univ. of Bristol Botanic garden whose original garden was built in 1879. They are on the edge of the carpark and get little attention but flower prolifically. I just take off any brown leaves at this time of year and pick bunches of flowers all through the year. They do not need feeding but I occasionally pinch pieces off the original clump for elsewhere in the garden and this seems to give them a boost. They do well under trees and by the sides of buildings so perhap full sun and threat of drought is not for them.
