A pretty South African Composite, known as the "Blue Marguerite", owing to its blue aster- or daisylike heads of blossom. It flourishes in a loamy soil with a little sand and leaf mould, and may be raised from cuttings of the half-ripened shoots almost at any time. It is often bedded out in summer. The variegated form is valuable for carpet bedding, as the leaves lie close to the ground.
