Senecio cineraria Dusty Miller

Edward F. Gilman and Teresa Howe


Dusty miller is grown for its spectacular foliage: silvery-white, delicately divided leaves covered with a very soft, dense fuzz. Reaching 12 to 18 inches in height, dusty miller is ideal for neat edgings or for breaking up large masses of flower color. It can be planted in containers where the foliage can be viewed up close. Dusty miller is especially dramatic when viewed at night, the silvery leaves catching and reflecting the faintest moonlight. While the small blooms are somewhat attractive, they are usually removed to encourage leaf growth.
