Teucrium castrense, also known as Castre Germander, is a perennial shrub from the Lamiaceae family, native to the Mediterranean region.

Care tips

It requires full sun for optimal growth and good flowering. This plant is very drought-tolerant once established, so watering should be sparse, allowing the substrate to dry out completely between waterings. It prefers well-drained soils, even poor or calcareous ones, and a common mistake is overwatering, which can lead to root rot. Light pruning after flowering helps maintain its compact shape.
