Dusty Miller
Jacobaea · Asteraceae
Dusty miller, botanically silver ragwort, carries what is probably the whitest foliage in all of floristry: deeply lobed leaves that look dusted with flour and appear frosted in a bouquet. It has been indispensable in wedding and winter floristry for years. We source our cut foliage in firm quality via the Veiling Rhein-Maas.

Botanically the plant is now Jacobaea maritima, though many still know it as Senecio cineraria or simply as cineraria. Two leaf types circulate in the trade: finely divided, fern-like varieties such as „Silver Dust“ and broad-lobed ones such as „Cirrus“, whose leaves almost recall oak foliage. Both are densely white-felted on either side — hence the silver effect.
In floristry dusty miller is a foliage for special moments. No other green brings as much brightness into an arrangement; next to white and blush it looks festive, next to bordeaux and deep violet, dramatic. In bridal bouquets it often replaces coarser eucalyptus when a softer, more romantic expression is wanted.
Its second big season is winter: in Advent arrangements, grave planting and winter bouquets the frost-white foliage plays the layer of rime that nature provides outdoors. As a bedding plant, dusty miller shrugs off light frosts and keeps window boxes silvery into December.
There is one trick to working with it: the felted leaves must not dip into the vase water, or they soak themselves full and rot. We strip the lower leaves generously and stand the stems in just a few centimetres of water — that way the foliage easily lasts more than a week.
Worth knowing: like many ragworts, silver ragwort contains pyrrolizidine alkaloids, which damage the liver in larger quantities. For normal use in a bouquet this is uncritical, but pets and small children should not nibble on it — a point we always raise with pet-owning customers.

Like other Senecio species, dusty miller contains pyrrolizidine alkaloids that can damage the liver when eaten. Toxic to cats, dogs and children — keep strictly out of reach and seek medical or veterinary advice if ingested.
Typical symptoms: After ingestion: vomiting, diarrhoea, loss of appetite; with repeated intake, gradual liver damage with lethargy and yellowing of the mucous membranes.

Overview: toxic & non-toxic plants for cats, dogs and children
Care
- 01Cut the stems at an angle and stand them in just a few centimetres of clean water.
- 02Remove every leaf that would touch the water — the felt rots quickly.
- 03Change the water every two days and rinse the vase.
- 04Keep cool and avoid splashing water onto the foliage.
- 05Keep out of reach of pets and small children.
- 06As a bedding plant: full sun, free-draining soil, sparing water — tolerates light frost.
Frequently asked
- Is dusty miller toxic to cats and dogs?
- Yes. Like other ragworts it contains pyrrolizidine alkaloids, which can damage the liver of cats and dogs after ingestion — the harm can build up gradually. Bouquets with dusty miller therefore belong strictly out of pets' reach; if ingestion is observed, seek veterinary advice.
- Why is the foliage so silvery white?
- The leaves are covered on both sides with a dense white felt of hairs. In its Mediterranean home this protects the plant from strong sun, wind and salt spray. That very felt creates the frosted look that makes dusty miller so sought-after in floristry.
- How long does dusty miller hold up in a bridal bouquet?
- Well hydrated, the foliage sails through a long wedding day even out of water — the felt slows evaporation. In the vase it lasts seven to fourteen days, provided no leaf sits in the water.
- Can you dry dusty miller?
- Yes, it dries well and largely keeps its pale silver tone. The leaves do become brittle, breaking more easily than cotton lavender or eucalyptus — so for wreaths, work it gently while still fresh and let it dry in place.
