About Sideritis glacialis
Sideritis glacialis, known as 'Hierba de la sangre' (Blood Herb), is a small perennial plant from the Lamiaceae family, endemic to the high mountains of the southern Iberian Peninsula. It stands out for its woolly, silvery leaves and yellow flower spikes that appear in summer, making it ideal for rock gardens, alpine gardens, or pots in sunny outdoor settings.
Native range
Mountains of Southern Europe (Spain, France, and Italy)
Care tips
It requires full sun exposure for optimal growth and abundant flowering. Watering should be infrequent, allowing the substrate to dry out completely between waterings, as it is very sensitive to overwatering and waterlogging. It prefers well-drained, sandy or stony soils with low organic matter content; a common mistake is planting it in heavy or excessively water-retentive substrates.

- First aid

- What kills it
- Excessive moisture and poor drainage are its biggest enemies, causing root rot. Also lack of light.
- Can it be saved?
