In the garden
A low, shrubby ground cover from Sardinia, Vinca difformis subsp. sardoa is grown where shade and a light, free-draining soil meet. Its season of interest runs through late spring and the summer months, with flowering from May to September. The plant belongs to the Apocynaceae family and is used where a spreading, low-growing shrub is required. Choose a position in partial shade or full shade; exposed, sunny sites are not recommended. It adapts to sandy and loamy soils across a wide pH range (acidic to alkaline) provided drainage is good. Moisture should be moderate — the plant tolerates soil that remains reasonably moist but does not stand in waterlogged conditions. Rated H4 for UK hardiness (average), it is suitable for most gardens that do not experience extreme winter conditions. Use it as a ground cover beneath taller shrubs, in rock gardens with shaded pockets, or at the front of a shaded border where a low, matt-forming shrub will fill gaps. Expect a sustained run of flowers from May through September, after which the plant continues to contribute low-level cover through the growing season.
