About
Watsonia rosea is a bulbous perennial in the iris family that produces its main flowers in summer between June and August. Native to South Africa, it is suited to a sunny, well-drained site and prefers moderate soil moisture. Plants form clumps from their bulbs and are best given an open, sunlit position. Allow good drainage and avoid sites that remain waterlogged through winter.

In the garden
Watsonia rosea belongs to the Iridaceae and originates from South Africa; it is a bulbous perennial valued for its summer flowering, with the peak display from June to August. It suits warm, open spots where bulbs can establish without sitting in cold, saturated soil. Choose a position that receives full sun for most of the day. Cultivate in free-draining soil amended where necessary with grit or sharp sand to improve drainage on heavier ground; maintain moderate soil moisture rather than constant wetness. Position bulbs so they get direct sun in the growing season and some airflow to reduce the risk of rot in damp weather. Water in dry spells while shoots are active but avoid overwatering once growth has finished. In a UK garden Watsonia rosea works well at the back of a sunny border, in gravel beds or sunny bankings where its summer flowers can be seen above lower plants. Planting in small groups gives a clearer summer display than isolated specimens. Expect the main flowering period to run from June to August, when the plant produces its seasonal blooms.
