Senecio

With its varied habits, foliage and flower forms, Senecio is a remarkably diverse genus. Commonly associated with ragwort and groundsel, Senecio plants range from herbaceous perennials to shrubs and other forms, but many garden varieties share the same characteristic daisy-like flowers and naturally informal appearance. Yellow blooms are especially typical, often held in loose clusters above divided or textured foliage, giving these plants a relaxed place in wildlife gardens, naturalistic planting and more informal borders.

Depending on the variety, Senecio plants can suit sunny borders, dry planting schemes or more naturalised areas, with individual species differing considerably in habit and growing requirements. Some forms are particularly valuable to pollinating insects, and ragwort species can support a wide range of wildlife, including bees and the caterpillars of cinnabar moths. Certain Senecio and closely related ragwort species are poisonous to horses and cattle, however, so they should be planted with care around grazing animals.

For UK gardens, Senecio offers distinctive foliage, open flowers and a less formal character than many traditional border perennials. Whether grown for its daisy-like blooms, interesting leaves or wildlife value, the genus works particularly well where planting is intended to feel loose, natural and full of life. Choose individual Senecio varieties according to their preferred conditions and eventual size, allowing each plant’s particular form to become part of the wider planting scheme.
