Introduction to Dusty Miller Plants

Every flower garden can benefit from the presence of dusty miller plants. Their silvery leaves add a touch of elegance and sophistication to any landscape, making them the perfect foil for colorful blooms. Whether you prefer cool purples and blues or hot reds and oranges, dusty miller is a versatile plant that pairs well with a variety of flower colors. Even white flowers can benefit from the soft glow of dusty miller’s wooly textured leaves, especially in moon gardens.

Dusty miller is a sun lover that thrives in full sun exposure. While it is typically grown as a tender perennial in zones 8 to 11, it can sometimes survive the winter in slightly colder climates. However, in colder regions, it is best grown as an annual. Dusty miller produces tiny bright yellow flowers that contrast with its silvery leaves, but to maintain a compact growth habit, consider removing the flowering stalks before the buds open.
