About Mexican blue sage
Salvia longispicata, sometimes referred to as Mirto in certain regions (though not the 'true' Myrtle, Myrtus communis), is a perennial shrubby sage from the Lamiaceae family, prized for its long and conspicuous blue-violet flower spikes. Its upright habit and prolonged blooming make it ideal for garden borders, mass plantings, or as a focal point in low-maintenance and Mediterranean gardens. It attracts pollinators and adds a touch of vibrant color and texture to the landscape.

Care tips
It requires full sun for optimal flowering and vigorous growth. Watering should be moderate, allowing the substrate to dry out between waterings, as it is drought-tolerant once established. It prefers well-drained soils, even poor or sandy ones, and does not tolerate waterlogging. A common mistake is overwatering, which can lead to root rot; it's better to underwater than overwater.
