In the garden

Clematis integrifolia olgae is a perennial member of the Ranunculaceae, native from central Europe to central Asia. It produces its flowering display from May to September and suits gardeners who want long-season interest from a non-vining clematis. In the UK it is classed H5, which means it is hardy across most areas of the country. Position plants where they receive full sun or partial shade; a south-facing, sheltered site is ideal. Use a fertile, well-drained soil with a neutral to slightly alkaline pH and keep the root area moist without allowing waterlogging. Good drainage is important; an organically rich soil will help retain even moisture while preventing stagnation. This clematis works well in mixed borders, containers or on a low support within rock gardens, where a sheltered microclimate can be provided. It is also suitable where a compact, flowering perennial is required rather than a climber. Take care when handling because the sap can irritate skin and keep rabbits away from foliage, as it is harmful if eaten; for further information and contact numbers regarding pets, see the HTA guide to potentially harmful plants.
