Winter Hardiness — Salvia x sylvestris L.

Salvia x sylvestris L.

The winter hardiness of the species is determined by its classification within USDA hardiness zones 3–9 and its critical dependence on soil drainage during the winter period.

In the reference 7 varieties crop Wood sage, where this is mentioned in the description.

Most Salvia x sylvestris cultivars are adapted to USDA hardiness zones 3–9. In professional practice, the winter hardiness of this species is assessed based on climate zone data, as there are no unified quantitative methods for measuring this trait in degrees or points.

A key factor for overwintering is not only resistance to low temperatures but also soil moisture conditions. Excessive winter moisture leads to root system death, which is often mistaken for insufficient frost resistance. Ensuring proper drainage is a prerequisite for maintaining plant longevity across various climatic conditions.
