In nature, Watsonia transvaalensis occurs en masse and is quite spectacular to see a whole field in bloom in early summer. They are endemic to the northern part of Limpopo where it occurs in well-watered areas.

The four leaves are rigid in texture and sword-shaped. The peduncle can contain up to 16 flowers and may be 1 m or more in length; the petals are deep pink.

Grow it in a damp spot for best results and keep dry in winter.
