Shrubby ragworts are useful foliage plants where the silvery leaves can be used to brighten a variety of areas.
Most varieties are wind and salt tolerant, making them very useful as seaside plants. They are drought tolerant once established.
Ideal as part of a Mediterranean style garden or as a ground-cover for a sunny well-drained site. Certain varieties make a good medium height hedge.
Water thoroughly during dry weather until well established. Mulch with organic matter in spring and apply a general fertilizer suitable for shrubs.
Dead head after flowering - although the fluffy seed heads can look attractive on some varieties.
Prune every few years after flowering, to maintain size and shape. Prune hedges after flowering.
Generally pest and disease free.
Semi-ripe cuttings can be taken in late summer.
