Bulbine frutescens leaves in drought

These Namaqualand Bulbine frutescens leaves show the blue-green or grey colouring that may prevail when the rain stays away for long, the sun is hot and some dust isn’t washed off. 

The long, sometimes terete or cylindrical leaves are here channelled and angular in cross-section, bulging less from sacrificing stored juice for sustaining plant parts elsewhere and everywhere on the body. These leaves may sometimes spiral (Euston-Brown and Kruger, 2023; Vlok and Schutte-Vlok, 2015; Shearing and Van Heerden, 2008; iNaturalist).
