Edraianthus owerinianus is a plant with a matforming, tufted habit in the genus Edraianthus, part of the Campanulaceae family, with deciduous or evergreen foliage. Edraianthus owerinianus grows best in full sun, and tolerates most soils and any pH. Its UK hardiness is rated H5. Suggested uses include rock garden, gravel garden and patio and container plants.
About
Edraianthus owerinianus is a mat-forming, tufted perennial in the Campanulaceae. It may be deciduous or evergreen and flowers in the UK from May to July. It prefers full sun on well-drained chalk, loam or sand and suits south- or west-facing positions. Its low, tufted habit makes it easy to use in rock and gravel gardens or in containers.

In the garden
Edraianthus owerinianus is a mat-forming, tufted member of the Campanulaceae that carries its main display from May to July. Plants may be deciduous or evergreen in habit and are rated H5 — hardy in typical UK conditions — so they will survive winter conditions in most outdoor situations. Give this species a sunny site and sharply free-draining soil: it performs on chalk, loam or sand and tolerates acid, neutral or alkaline pH provided moisture does not remain. South- or west-facing aspects suit it best, and it will take both exposed and sheltered positions where drainage is good. Keep soil reliably free-draining whether grown in the ground, gravel pockets or shallow patio containers. Use Edraianthus owerinianus where a low, mat-forming perennial is needed: rock gardens, gravel beds, patio troughs and containers are all appropriate. Position plants so their tufted habit remains visible and so the May–July flowering period sits at eye level for the border or container display.
