Propagation and Dividing Dusty Miller

If you want to expand your Dusty Miller garden, there are two main methods of propagating and dividing the plant: seed collection and stem cuttings. Division is also possible for established plants that have multiple stems.

Seed Collection

When the flowers of Dusty Miller dry out and turn brown, they produce seeds that can be collected for propagating new plants. However, be aware that Dusty Miller is not a particularly reliable self-seeder, and the resulting plants may not be true to the parent plant. If you choose to collect seeds, wait until the flowers have turned brown and dry on the plant. Once fully dry, gently shake the flower heads to release the seeds onto a sheet of paper. Clean out any debris and transfer the seeds to an envelope or seed packet, store it in a cool, dry place until planting time.

Stem Cuttings

Propagating Dusty Miller from stem cuttings can be another way to expand your garden. Select a healthy-looking stem with several leaves attached and cut it just below a node. Strip the leaves from the lower half of the cutting and dip the cut end in rooting hormone. Plant the cutting in moist, well-draining soil, and cover it with a plastic bag to create a humid environment. Keep the soil moist and the cutting in a warm and bright location until it roots and new growth appears. Once rooted, the cutting can be planted in the garden.

Division

Established Dusty Miller plants with multiple stems can be divided to propagate more plants or to thin out overgrown clumps. Using a clean, sharp knife, carefully dig up the plant and separate the stems or root clumps, ensuring each division has some roots attached. Replant the divisions in well-draining soil and water them thoroughly. It’s best to do this in early spring or fall when the plant is not actively growing.

With these simple propagation methods, you can easily multiply your Dusty Miller garden and enjoy this beautiful plant in different areas of your landscape.
