What is the dusty miller plant? The botanical name Senecio cineraria, the plant originates from the arid regions of the Mediterranean. It is also known as silver ragwort or jacobaea maritima. The scientific name is often either misspelled as “cenecio cineraria” or mistaken for centaurea cineraria. This mound forming plant grows to 12″ inches tall and is an ideal choice for flower bed edging or companion planting.
