In the garden
Watsonia densiflora is a bulbous perennial in the Iridaceae, originating from KwaZulu-Natal and the Eastern Cape of South Africa. In cultivation it contributes a clear summer phase, flowering in the UK from June to August. The species’ southern African origin means it performs best where it receives strong sun through the main growing season. Site selection is straightforward: choose a location in full sun with well-drained soil and avoid waterlogged hollows. Maintain a moderate level of soil moisture through the growing season rather than constant wetness; established bulbs appreciate a drier rest when above-ground growth dies back. Feed lightly in spring with a balanced fertiliser if the soil is poor, and protect from winter waterlogging in cooler, damp areas of the UK. Use Watsonia densiflora where you need reliable midsummer interest in sunny borders or mixed perennial beds. Because its main flowering window is June to August, place it where surrounding plants can be timed to either lead into or follow on from its display, so the bed remains active through summer.
