The blue Mexican sage or germander sage (Salvia chamaedryoides) is a plant of the mint family (lamiaceae) of little more than half a meter of height.. Stems multiple, compact, erect, hairy gray. It grows in clumps of one meter or a little more wide

Gray hairy leaves about 2.5 cm long by 1 cm wide. The scientific name of this plant "Chamaedryoides" is given by the fact that its leaves remind to those of germander (Teucrium chamaedrys). In fact, in English, this plant is known as Germander sage.

Dark blue violet flowers. It blooms throughout the year, although it reaches maximum flowering during summer and fall.

It grows from Texas to Mexico, on raised lands between 2000 and 2800 meters above sea level.

There is a variant with lighter colored flowers, very cultivated in gardens. (Salvia chamaedryoides var.isochroma)

Cultivation of Mexican blue sage

- Very drought tolerant, it needs very little water once it is well established. In hot summers and with scarce rains you should provide it some irrigation to get more flowers, although germander sage can live without any irrigation, except the rain.

- Frost hardy to -10 or -17ºC. In which case it loses the outside of the plant that recovers again when the good weather comes.

In climates not so extreme and cool, leaves tend to lose some of the leaves and, when planted in warmer climates, it behaves like perennial, maintaining the foliage throughout the year.

It does not like a windy exposure, so plant it somewhere protected from the wind.

- Very suitable for beds and edges or to adorn rocky gardens. It also behaves very well as a potted plant or in big containers, providing a very interesting aroma.
