Dusty miller helps the garden to maintain its beauty throughout the heat of the summer.
Although, its flower bloom is mid-summer small yellow blooms are not considered snowy because they are small and they are also frost tolerant.
The plant size grows 1 foot tall and few flowers bloom in the late summer. This plant is grown as an annual and discarded after the first season.
However, it might be common in USDA Hardiness Zones 8-10, where it is often grown as an herbaceous perennial.
- Trim the plant, if it becomes leggy mainly in the mid-summer.
- Although Dusty miller produces lovely flowers, most gardeners find them useless and tend to cut them.
- Remove Dusty miller flowers to make them compact or enjoy their beautiful yellow bloom.
Tips to Grow Dusty miller
They grow a bit overcrowded, so you have to maintain a bit of space about 9 – 12 inches for healthy growth.
Silver ragwort grows faster if you cut them, and find small parts which become woody or snip. Keep them watered and start cutting in a good-quality potting mix.

You can boost growth and produce a more reliable yield by using a rooting hormone. This is an optional step, plant do root without any supplement if provided in good condition.
Keep in mind to snip the flowers if they have grown from their cutting, to increase root and leaves development. This is not essential if your plant is already established in the garden.
However, it becomes an important factor if you attempt to start a new plant by cutting through strong roots.
All varieties of Silver ragworts are best for gardening. Some are very fine, while others are only slightly lobed.
- Variety like “Cirrus” has broad leaves with scalloping on the edges.
- and “Silverado” is the fern-like foliage popular in many gardens.
- Whereas, “Silver Lace” has very fine foliage, as the name implies.
As I earlier mentioned, this species is not good for growing from seed. It might show unexpected results.
Instead, it is better to find plants at your local nursery or garden center. But if you want to give it a try, I will recommend the Silver dust cultivar.

How to propagate dusty miller from division
The ideal time to grow from the division is in the fall season when the dusty miller gets dry. By division, you’re able to grow multiple identical plants of the same cultivar.
This is not true with propagation from seeds. Nowadays most plants are cultivars or hybrids if you try to regrow from their seeds. It will not grow identically to the parent plant.
Here, is how to do division or propagation from stem cutting:
- First, make a spot to plant stem cutting. Rub the soil to make it smooth, where you have decided to grow.
- Root out dry dusty miller from the soil, do this with your hand (gardener gloves on the hand).
- Split the stems and make different stem cuttings. Take a shear and cut the bottom end of the stem cutting.
- Cut till a white-colored tissue gets visible. Make these stem-cutting stands in the soil by using your hands.
- Sprinkle some nitrogen-rich fertilizer on the surface of the soil, this will help the stem to grow roots quickly.
- After some time, spray water on the soil to make it moist.
- The stem cutting will start rooting in 2 weeks and after a month they get well established.
- You also grow them in pots by the division method.
Can dusty millers grow in water?
The dusty miller is a plant that can be propagated in water, although it is not normally a plant that thrives permanently in water. The Mediterranean area is its natural habitat, and soil is the most common medium for growing this beautiful plant that lives for many years.
Having said that, you may start new plants from cuttings by using the water propagation technique, and after the plants have established roots, you can move them to the soil to continue their growth. The propagation of many plants, including dusty miller, is often done in this manner.
How to Propagate dusty miller in water
These are the measures that need to be taken in order to propagate dusty millers in water:
- Pick a strong stem from the plant and cut it just below a node where leaves are attached (the point where the leaf attaches to the stem).
- Take off the leaves that are closer to the base of the stem, leaving just a couple at the very top.
- After filling a small jar or glass with water, insert the stem inside of it while taking care to ensure that the leaf node is completely buried in the liquid.
- Put the jar in a warm, bright spot away from the direct rays of the sun.
- It is recommended to change the water every few days in order to maintain its quality.
- Following a period of a few weeks, roots should begin to develop at the leaf node. When the roots have grown to a length of a few inches, you may then transplant the stem into the soil.
- Be sure to give the plant plenty of water and continue to tend to it in the same manner as you would a mature dusty miller plant.
It is essential to cut the plant using a tool that has been well-cleaned and disinfected before use in order to prevent the spread of any illnesses or infections to the plant. To further reduce the risk of infection, you should be sure to use clean water and a clean container, such as a glass or jar.
