buddlia

You can trim it once flowering is over but in early Spring you can prune it hard back and it will flower on new wood. I like to leave some of the old wood so that there is a succession of flowering, old wood first, young wood following.. It is one of my favourite shrubs

Do you know the name of your Buddleja?

I am not aware of a dwarf Buddleja , would be interested to know the name too?

Hi Dwarf Buddleia is usually Nannho Blue. It is still likely to reach 6ft. but leaves are only half size and it is easily kept as a 4 or 5ft. shrub. Pruned hard back in early Spring. Butterflies love it
