This is a wonderful plant in the summer garden and equally good in the winter garden. (The top photo is from our 50 degree day in late January.) We got a little snow this morning and it looks very happy. It is called a rosemary-leaf santolina (Santolina rosmarifolia). It has the yellow button flowers and smell of the santolina, but the leaves of a rosemary. I love the blue-green color in the winter garden. Here it is just a little while ago. I found this wonderful plant at Mulberry Creek Herb Farm in Ohio several years ago. I think their mail order days are over, but they are located near Cedar Point in Huron, Ohio and I know they would love you to come and visit them.
