Salvia mellifera

Salvia mellifera, the Black Sage or honey sage, is a botanical species from southern California with remarkably aromatic foliage: its leaves emit a sweet scent of honey and Eucalyptus in hot weather. Its very pale flowering in early summer is nectar-rich, but not very spectacular.  This sage is perfect for rockeries or borders in a dry garden, highly beneficial to bees, best suited to mild climates and well-drained soils, dry both in summer and winter. In colder regions, it can be grown in pots, allowing it to be stored indoors during wet and severe frost. Place it on the terrace or near well used areas to enjoy its fragrance.

Salvia mellifera thrives in regions which are very hot and dry in summer. However, its cold resistance is quite limited: the crown dies below -8 to -10 °C, or even at -5 °C if the soil is moist. Like all other salvias, it belongs to the large family of lamiaceae or labiates.

Salvia mellifera is a woody-based perennial plant. It forms a branched and generally rounded clump that can exceed 1.20 m high when flowering, with a spread of 80-90 cm. Under certain conditions, the plant can reach a height of 2 m and form a very wide clump, 1 m in diameter. Its foliage is theoretically evergreen in winter. It consists of elongated, hairy, fairly dark green leaves. They are elliptical, with a crenate edge. These leaves release an intense fragrance, especially in dry and hot weather. They are covered with small glands from which essential oils drip. Flowering occurs from June to August, depending on the climate. From the foliage tall, unbranched flower stalks bearing small flowers emerge that are slightly bluish, or even white, arranged in whorls around the stem. They are intensely nectar-rich and loved by bees.

Salvia mellifera thrives in full sun on dry slopes, rockeries or borders on gravel, in consistently well-drained soil. It cannot tolerate poorly drained soil and damp cold. Pair it with large lavenders ('Grappenhall', 'Meerlo'), rockroses, cotton lavenders, or even the variegated Euphorbia characias 'Glacier Blue'. When grown in pots, use large containers with a very well-draining growing medium and water sparingly.

With over 900 species of annuals, perennials, and shrubs distributed worldwide, except in very cold regions and tropical forests, the Salvia genus is the most diverse in the lamiaceae family. The name Salvia, dating back to Roman times, derives from the Latin salvus "healthy," alluding to the medicinal properties of common sage.
