Looking for advice to plug a big hole left by the snow killing a stand of echiums . I was hoping they might rally but they all clearly properly dead. It’s about 3m x 2m, acid soil , reasonable sun but quite windy in a large bed with mature trees behind . Camellias do very well there but I’ve got a few in there already so trying to be more adventurous. Could get some hydrangeas but again have some elsewhere. Looking for small trees or big shrubs . Just thinking about an elder maybe? Also open to things like gooseberries / fruit trees eg sour cherry but not sure about the exposed site. I’m a beginner so any advice welcome.
