As the leaves were beginning to fall last year, I decided to see if I could overwinter rosemary. I cut several tender branches and placed them in water to see if they would root. In time, some did. And when the roots were sufficiently developed, I planted each sprig in it's own small pot. Only one plant made it through the winter. Mind you, I probably could have increased the chances of all of the cuttings if I had used grow lights on some of the dark cloudy days of winter, but I was trying to see if I could manage to be successful using a minimum of resources.
I'm glad that the plant that did survive is growing so robustly. I guess my experiment proves you don't need a great deal of green if you want to keep some green in your life.
