Maintenance- Design- Planting Tips

Watsonia is a South African plant that grows well in the Santa Clara Valley. The pink gladiolus-like flowers are a highlight of late spring gardens. The sword-shaped leaves provide strong accent points in beds. Some retail nurseries carry a selection of Watsonia corms (bulbs) in the fall.

PADG Notes: This is a summer dormant plant, which means it can get by on almost no water in the summer but has unattractive leaves starting in July. We solve the ugly leaf problem by cutting the leaves back to a couple inches above ground in mid-summer. This results in a bare spot in the bed. If that bothers you, install a plant next to the Watsonia that will fill in the bare spot during the summer and fall months.
