Garden Sage: Botanical Profile & Identification
Garden sage (Salvia officinalis) is a perennial, woody herb in the Lamiaceae family, native to the Mediterranean region. Known for its silvery-green, velvety leaves and distinctive, aromatic flavor, this herb is a cornerstone of both culinary and medicinal traditions. Garden sage typically grows to about 60–80 centimeters in height, with a bushy habit that supports clusters of delicate, violet-blue flowers in late spring to early summer.
Taxonomy and Classification
- Family: Lamiaceae
- Genus: Salvia
- Species: Salvia officinalis
- Common Names: Garden sage, common sage, culinary sage
Morphological Characteristics
Garden sage is easily recognized by its:
- Leaves:
The leaves are oval, covered with fine hairs, and display a grayish-green color with slightly serrated edges. Their pungent aroma intensifies when crushed, releasing essential oils. - Flowers:
The flowers are arranged in whorls on spikes. Typically blue to violet in color, they add ornamental appeal and attract beneficial pollinators such as bees. - Stems and Growth Habit:
