The trumpet-shaped, orange to orange red flowers of Watsonia pillansii grow in a two-sided spike comprising about 35 flowers. Three to eight flowers are usually open concurrently, occasionally more.
Two green, greyish green or dark red bracts clutch each flower base firmly close to the stem, alternating up it. The bracts are about 3,3 cm long, their tips soon dry. The down-curving corolla tube is about cylindrical in its upper part. The six tepal lobes spread to a diameter of about 3 cm.
Blooming happens from late spring to after midsummer (Pooley, et al, 2025; Manning, 2009; Pooley, 1998; Gledhill, 1981; iNaturalist).
