It is a very exposed, windy and can get very cold in winter in the Dublin Mountains Ireland. Was thinking of Phormium jester or agapanthus.

Answer 1

The jester may be too short and not withstand the cold. But a similar ornamental grass that is hardy would be superb.

Agapanthus and purple coneflower would be nice in one or more planters.
