Description

Oleraia phlogopappa grows to between 0.3 and 3 metres in height. The leaves are quite variable, but are usually grey-green with minute hairs on the underside which impart a whitish or yellowish appearance. The leaf margins are often bluntly toothed. White, pink or mauve "daisy" flower heads around 20-25 mm in diameter are mainly produced in spring and early summer.
