Be the first to Write a Review Berggarten is an especially aromatic and flavorful variety of sage (Salvia officinalis) that particularly enhances pastas, roasted meat and poultry, stuffings and cream sauces. The leaves also can be steeped in hot water to produce a soothing tea, a natural remedy for sore throats. Snip the gray-green leaves as needed, and this perennial plant will keep producing all year. Spikes of purple flowers bloom in midsummer and will attract honeybees to your garden.
