Acorus Ogon is evergreen grasslike plant that spreads quickly and well. It will merge pond edges. on the outside ajuga will spread nicely with reddish foliage and purple flowers and is evergreen. On the outer edge ferns are perfect.
Chameleon grows well in the pool....not evergreen but vigorous in foliage colours of red, cream,,pink,,yellow etc and orange scenfed white flowers. Grows to 50 cm. lobelia Victoria is a tall purple foliaged perennial with scarlet flowers in mid summer onwards. Try growing this lobelia in the shallow edge AND in the ground bordering the pond to create continuity. Grows 60 plus cm. all of these grow on the shelf in the pool not in the deep parts of it. Arum lily too is a consideration.
Astilbes, primulas, astrantias and a fav grass of mine, viz., hackonochloa which will cascade into the water, will look good out of the pond but edging it.
