About Glandora rosmarinifolia
Glandora rosmarinifolia, also known as Rosemary-leaved Gromwell, is a small perennial shrub from the Boraginaceae family, prized for its intense blue flowering. Its narrow, linear leaves resemble those of rosemary, and it becomes covered in tubular flowers in spring and early summer. It is ideal for rock gardens, Mediterranean gardens, or as a border plant, providing a vibrant splash of color.
Native range
Southwestern Europe and Northwestern Africa
Care tips
It prefers full sun exposure and well-drained, slightly acidic to neutral soil. It requires moderate watering, allowing the top layer of the substrate to dry out between waterings, and is drought-tolerant once established. Avoid waterlogging at all costs, as it is very susceptible to root rot. It does not tolerate severe pruning well; opt for light pruning to maintain its shape.
