Senecio cineraria also known as Dusty miller is a species of Senecio from the family Asteraceae, a native perennial of the Mediterranean and widely cultivated as an annual for its silver, felt-like leaves.
Senecio cineraria shares the common name Dusty miller with other plants that also have silvery leaves; the two most often to share the name are Centaurea cineraria and Lychnis coronaria.
Jacobaea maritima is a very white-woolly,[1] frost tender, heat and drought tolerant, evergreen,[2] perennial, dicot, subshrub[3] that can grow to be 2 ft m 1 or less tall[1] and 18 to 24 inches (45 to 60 cm) wide.[2]
Leaves and stems: Stiff stems[2] branching from the base, and covered in long, white, matted hairs. The leaves are lance-shaped, 2 to 6 inches (5 to 15 cm) long, serrated, pinnately cut,[2] stiff, with oblong and obtuse segments,[1] numerous and like the stems, also covered with long, white, matted hairs.[2]
Flowers: Yellow or white in daisy-like,[4] 1.5 in cm 0 wide,[2] rayless,[1] compact flower heads resembling a single flower, but really composed of several florets inclosed in a common whorl of sepals or ring of bracts at the base of the flower stalk.[1] S. cineraria does not produce flowers the first year.[4]
Seeds: Fruit are cylindrical achenes.[2]
