Tree Germander (Teucrium fruticans)
Tree germander is an evergreen shrub from the mint family. It has silvery foliage and delicate flowers. Typically, it reaches a height of 3 to 6 feet (0.9 to 1.8 meters) and spreads to a similar width. The leaves are small, ovate, and covered with fine hairs, giving them a silvery-gray appearance. Its stems are woody and upright, creating a dense, rounded habit. From late spring to early fall, it produces pale blue or lavender tubular flowers, which attract bees and other pollinators.
Native to the Mediterranean region, tree germander thrives in dry, rocky soils and full sun. It tolerates drought and saline conditions, making it a popular choice for coastal and xeriscape gardens. This plant is primarily ornamental, often used for hedges and ground cover, but it also possesses mild medicinal properties. Its hardy nature and visual appeal contribute to its versatility in landscaping.
