Dusty MIller as a Perennial?! Believe it!!
I had to share this trick I've picked up with all of you. About 6 years ago we purchased a flat of Dusty Miller in the early summer and planted it in the normal fashion. Shortly afterwards baby #4 was born and that fall left me too busy to pull out my annuals before snow fell. Oddly enough, most of the Dusty Miller looked pretty, even in the winter. The next spring, still busy with 4 little ones, left me unable to 'clean' out my flower-bed. By the time my oldest got out of Kindergarten that May, my Dusty Miller were thriving, all on their own. I finally got down and dirty and trimmed the hard, dead stalks and leaves off the new, young foliage. I always cut off the flowerings as they occur, but that first summer I did allow a few to go to seed for collection. Now, my original flat of Dusty Miller are big, beautiful 'bushes'. I've never taken them out in the fall, just leave them and I don't even prune them until about May. This spring it looked as though I might lose them all, they looked pretty bad....the neighbors were joking about my 'Adam's Family Garden'. But I left them anyway and now I've got the last laugh, they're gorgeous!! They measure anywhere from 18' wide to 12' tall.
Take a look for yourselves at a 6-year-old Dusty Miller!! I'll post the two photo links I have...
