Holothrix grandiflora is a robust, tuberous perennial reaching heights from 19 cm to 58 cm.
The species distribution is in the Western Cape from the Olifants River and the west coast across the Little Karoo and the Agulhas Plain near Bredasdorp to the Eastern Cape as far as Gqeberha. The photo was taken on the Minwater farm near Oudtshoorn.
The habitat is semi-arid sandstone or quartzite outcrops and among fynbos and shrubs at lower elevations. The information for determining the status of the population in nature is lacking early in the twenty first century (Vlok and Schutte-Vlok, 2015; Liltved and Johnson, 2012; Bond and Goldblatt, 1984; iNaturalist; http://redlist.sanbi.org).
