An easy but rarely offered evergreen japanese perennial from Honshu to Shikoku.
Lanceolate evergreen leaves are semi-glossy and slightly serrated, around 5 cms long but only 1 cm or so wide. It forms dense low clumps of foliage and spreads by stolons mainly although it will thicken up by rhizomes.
The flowers are small but numerous giving rise to it's common name 'Japanese Foam Flower'. These are creamy coloured and a fine scent is also present. Easy on moist fertile soils but will tolerate a degree of dryness once it is established.
