Dusty miller plants that survive winter produce clusters of small yellow flowers in spring. The flowers are usually clipped off to encourage the plants to develop new leaves. The light-catching gray foliage of dusty miller makes it a good choice for areas used in the evening.
Snip off blossoms and old leaves to keep plants looking neat. In fall, gather and dry perfect leaves before the plants are damaged by freezing weather.
Too much water or very high humidity can occasionally lead to problems with diseases.
