Where does the name come from? In Volume 3 of the trivia series on this website there is a unit on old mills. Those of us who have been in such a mill, while in operation, have seen white flour everywhere unless corn is being milled, then it is yellow. Over hours of working in the mill the miller is practiaclaly covered with white flour. Someone back in botanical history thought of a dusty miller when he/she saw, then named the plant. Hence, the name dusty miller.
These are good for borders, and are deer proof! Perhaps the wooly surface of the leaves discourage deer for it does not feel good on their tongues.
There is a “Dusty Miller Jig” to play on your mandolin is you choose.
