This semi-herbaceous/semi-woody herb is an extraordinary performer. And, yes, there are two “G’s” in the name. Typically, I wouldn’t recommend an herb for commercial landscape projects, but this one doubles as a fine evergreen ground cover as well as a culinary flavoring. It forms thick mats of bright green, thick foliage that morphs to grey in the winter. Wait until early spring to prune back old, woody growth, just as you should for all herb plants. Pruning in the fall can open stems to moisture and decay.
If you have colorful conifers nearby, Berggarten sage is a perfect counterpoint. The contrast of pale, purplish-blue-grey looks striking next to lime golds, pinks, and oranges. The leaves are much wider than regular garden sage, too. Regular garden sage burns out and goes spindly at the end of fall, but Berggarten sage revives and thrives with the change of seasons.
You will love this plant so much, you’ll want more of it. That’s simple. Just root the long, thin, old growth when you prune in the spring.
