Rosemary is such a wonderfully armoatic plant. I wasn't sure I would like it when we planted it at the end of the walkway up to the front door but it's still one of the best things when I come home. As I brush against it walking by it fills the air with its scent.
It's also one of the hardest plants to kill. I rarely water it and, even in the hot July months of Texas, it just doesn't care and keeps on growing. if all plants did this there would be no such thing as a desert.
You also can't cook with all plants so I guess it evens out in the end. It keeps growing and I keep eating it. Well, not by itself but on pork or chicken or in a cream sauce over noodles. Any of these options will do.
It's also good for sachets!
