Description
Originating in Central America, Seaside Daisy is a low sprawling herbaceous perennial with a woody base. It is common in rockeries and as a border planting. Growing in clusters around the stem, leaves are light green, slightly hairy and often lobed.
Large numbers of small daisy flowers with a yellow centre. Open white, ageing to pink. Flowers all year, and mainly in summer. Each flower produces many small, light seeds.
Dispersal
Seeds are dispersed by wind and water. Stems layer and broken roots regrow. Often dumped as garden waste.
Impact on bushland
Reproduces and spreads rapidly to form dense mats. It can grow in almost any open habitat, including watercourses. Crowds out and displaces ground level plants.
Control
Manual:
- Stems tend to become brittle and break off.
- Pull or dig out.
- Can also be cut and painted using a neat glyphosate based product.
See Manual Weed Control Techniques.
