As I remember this has a yellow flower, but it has been so long since I saw one in bloom, I forget. Also known as Bible Leaf, it was pressed in the bible you carried to church to be crumbled under your nose, to wake you up. It has a strong chemical and mint smell. Not unpleasant, but you would not want a perfume. It can grow a couple of feet high in good soil.
A little butter and sage makes a wonderful sauce for pasta etc. I love it and it is hardy here. However I buy new plants every other year as it does not seem to be long lived. the new one on the right is struggling in the heat of June.
