Dudleya brittonii, with the common names Britton's dudleya and giant chalk dudleya, is a succulent plant in the family Crassulaceae. It is native to Mexico and cultivated as an ornamental plant in well-drained rock gardens and as a potted succulent.
The 'silver dollar plant' (Dudleya brittonii) is a solitary, succulent plant in which the stem terminates in a rosette of slender leaves densely covered with a white, waxy coating (farina). However plant may sometimes be found without its grey, waxy coating (farina), but these plants are not as popular. It makes neat, compact plants with juicy, spatulate leaves of a watery sea-green colour, covered by waxy bloom. Flower stems are bright red and very showy combined with the starry, pink-bracted yellow or orange flowers above. As the plants mature, the old dead leaves hang on and form a rough "tutu" on the main stem. It is the most common in cultivation, resembles a chalky gray echeveria (Dudleya pulverulenta), but Dudleya brittonii grows larger, eventually forming a solitary rosette 50 cm in diameter.
