Euphorbia tuberosa flowers, false flowers or cyathia do make a strong colour statement, supported by the leaves when attacked as here by the relentless Namaqualand sun.
Replenished as needed by the invisible tuber hidden below-ground, the lush flowers are surrounded by five yellow-green, flat and succulent lobes that dominate the pointed bracts sometimes protruding more conspicuously from below (Grenier, 2019; Frandsen, 2017; Vlok and Schutte-Vlok, 2015; Manning and Goldblatt, 1996; iNaturalist).
