There are several different dusty millers within the genus Centaurea. All are grown for silvery gray foliage, useful when mixing flowers of contrasting colors. They grow in any fertile, well drained soil and prefer hot, dry, sunny locations.
Dusty miller is propagated by seed or cuttings. The seeds germinate in 10 to 15 days at 75 degrees. Do not cover the seed. Centaurea candidissima seeds require temperatures of 60 to 65 degrees and are germinated in darkness.
There are no serious pest problems.
