Craspedia glauca, partly
Craspedia from the Greek 'kraspedon' meaning a hem or border, referring to the woolly fringes on the leaves of the type species or the feathery pappus of some species. Paludicola from the Latin 'paludosus' meaning marshy and 'cola' meaning dwelling, alluding to the species' usual habitat in swampy sites.

Flower heads solitary, globular shape with bright yellow dense flowers. Flowering in spring and summer. Fruits are yellow-white, globular daisy-head. Seeds are brown ovoid seed to 2 mm long and 1 mm wide, covered in white hairs. Seed embryo type is spatulate fully developed.
Seed collection and propagation
Collect seeds between October and February. Collect heads that are drying off, fluffy and turning yellow-white with hard brown seeds. Pick off whole heads or pluck off mature seeds with your fingers. Place the heads in a tray and leave to dry for one to two weeks. Then rub the heads gently by hand to dislodge the seeds. Use a sieve to separate the unwanted material. Store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was average, at 55%. Seeds are non-dormant, viable seed should germinate readily.
