In the garden

Acanthus balcanicus is a herbaceous perennial in the Acanthaceae, native to the Balkans and grown where a strong architectural element is needed. It carries its presence through a compact perennial habit and a season of blooms that occur from June to August. Position it in full sun or partial shade and give it moist, well-drained soil; good drainage is important even where the soil is reliably damp. The species is rated H5 for UK gardens, meaning it is considered hardy across much of the country and will tolerate typical winter conditions in those zones. It performs well in heavier soils provided they are not waterlogged. Use Acanthus balcanicus at the back of a mixed border, as a focused architectural planting, or where tall flowering stems are wanted to punctuate perennial beds. Its seasonal flowering period — June to August — is when the plant contributes vertical structure and presence to borders and architectural groupings.
