Sage is a pretty tricky herb. I think Clary sage is the variety that I usually grow. I've tried bicolor sage before and it never makes it past midsummer. I tried golden sage and it shared the miserable fate of the tricolor. Silver sage was nice for a season. It had a very distinctive foliage but I didn't have anything to do with it except for letting it look cool in the garden. I need to harvest the sage at the end of the fall. Cut the stalks down and harvest the dried leaves. This spring there is a nice crop of new growth coming from the bottom of the plants.
