Like "It has soft leaves so low humidity might be a bother to it. I have only two plants right now to experiment with. You dry the leaves or steep fresh ones and from the links that Kaiyle gave, the ones the average person gets may not be as sweet as the commercially grown ones, but they are still sweet. So for about $3 you can get one and give it a try. The links below are very helpful. Oh and your rosemary should survive quite well outside even in winter. It is an evergreen plant and holds up well in the cold."
