Salvia frigida is a herbaceous perennial in the family Lamiaceae. [1] It is native to northern Iraq, northwestern Iran, and eastern Turkey growing at 900 to 2,500 m (3,000 to 8,200 ft) elevation. It is often found growing in Anatolia, on woodland edges, meadows, limestone slopes, and crevices.

The plant prefers friable soil, good drainage, moderate water, and three-quarters to a full day of sunlight. In the UK, seed can be sown in late March in a greenhouse or directly into the border after the last frost. [1]
Some cryoprotective agents used in research are inspired by plants and animals in nature that have unique cold tolerance to survive harsh winters, including: trees, [3] [4] wood frogs, [5] and tardigrades. [6] The first human corpse to be frozen with the hope of future resurrection was James Bedford's, a few hours after his cancer-caused death ...

[3] Violet-blue spikes rest on a compact plant of typically narrow salvia-like leaves; however, the shiny leaves are what set this species apart from most other Salvia ...
Additionally, wind chill can make a significant difference in staying safe out in the cold. “If [it’s] below -15 degrees Fahrenheit, it’s a good day to play inside.
