Picture of 'Silver Dust' dusty miller plants (Senecio cineraria 'Silver Dust'). While its silvery color is striking, this dusty miller has more than just color going for it. The delicate foliage texture of 'Silver Dust' dusty miller, with its deep indentations along the edges, contrasts strikingly with adjacent plants whose leaves have smoother edges, whether it be geraniums (as in the picture above) or red salvia.
