Glandularia lilacina, commonly known as Cedros Island Verbena, is an evergreen subshrub native to the coastal scrub and chaparral of Baja California. It typically grows to a height and width of 3 feet, featuring erect stems and narrow, elongate bipinnatifid leaves that give it a fine-textured appearance. The plant is adorned with clusters of vibrant purple flowers that bloom in fall, spring, and summer, adding a long-lasting splash of color to the garden landscape.

Cedros Island Verbena is valued for its drought tolerance and the extended flowering period, which provides visual interest for much of the year. It is well-suited for use in rock gardens, xeriscaping, and as a border plant, where its low water requirements and ability to adapt to various soil conditions, including heavier soils, are advantageous. While it thrives in full sun, it can also perform well in part shade. This subshrub is hardy to USDA zone 7 and benefits from well-draining soil to prevent root rot. Cultivars offer gardeners a choice of flower colors and plant sizes. Potential problems include susceptibility to spider mites and root rot in poorly drained soils.CC BY-SA 4.0
