A well-deserved Award of Garden Merit (1993)*
Senecio cineraria 'Silverdust' or silver ragwort is a perennial subshrub that belongs to the Aster family.
It has finely indented, beautiful and highly ornamental silver foliage, which makes it a great choice to break up the monotony of a bed, by adding a flash of contrast or to decorate compositions in a planter.
As border edging with Salvia, Sedum, Thymus or Dianthus.
Senecio cineraria 'Silverdust' is a xerophyte (desert plant) and is happy in full sun and in ordinary soil that can be poor and dry.
Like most other silver leaved perennials, this plant does not like too much damp or heavy, badly-drained soil.
It is ideal for temperate climates (zone 8b to zone 10) and by the sea can put up with salty sea breezes and does not mind the wind.
In continental zones (zone 5 to zone 8a), this plant can be grown as an annual, but will only withstand subzero temperatures if the soil is properly drained.
Maintenance: deadhead and prune in the spring to keep the bushy habit.
