This part of my garden is a horticultural representation of the Hokusai's famous print 'The Great Wave of Kanawaga' (see https://theculturetrip.com/asia/japan/articles/hokusai-s-great-wave )
There is a mound representing Mt Fuji, with silver foliage/white flowering planting on top to represent snow, and two weathered limestone rocks represent the two fishing boats.
Planting includes large diagonal drifts of perennials in mostly blue/pink/white colours, some chosen for their ability to remain still (e.g. Bergenia, Agapanthus, Kniphofia) and others which will move with the wind (Phlox, grasses). Key shrubs and conifers add height and representing the great wave itself is Sequoia sempervirens 'Adpressa'.
As in other areas of the garden, this is not just a summer display - it's intended to have interest year-round.
This area needs time to develop, more than any other area in the garden, so as yet there are few photos!
