You won't find this herb in any supermarket. The only place where you can always buy it - Union Square Farmers Market in NY. It's sold potted, so you can use top of the branches to spice lamb and beans in any form. It's funny but Germans call this herb Bohnenkraut which literally means 'herb for green beans'. Many people use dried and grounded summer savory as a replacement of black pepper if they are allergic to it.
Since I moved to rural area I grow herbs to use fresh in a spring/summer/fall seasons or dry in winter.
Here is the Satureja hortensis - It plays an important role in Georgian cuisine and is called qondari.
