About Jurisic's Sage

Salvia jurisicii · also called Jurisic's sage, Jurisic sage · herb

Salvia jurisicii is a compact, silvery-grey perennial sage native to rocky limestone slopes in the Balkans (Serbia, North Macedonia). It thrives in full sun, sharply drained alkaline soil, and tolerates prolonged drought once established — making excellent drainage the single most important care factor. The finely divided, silky foliage and violet-blue flower spikes in early summer make it a choice rock-garden plant. Salvia is not listed on the ASPCA toxic plant database; out of caution, treat as mildly toxic to cats and dogs.

Cold limit: USDA 5-9 · RHS H5 (-15 to 30°C)

Watch for — Crown and root rot: The most common cause of death; caused by poorly drained or clay-heavy soil combined with winter wet. Plant on a raised bed or slope and incorporate 30–50% grit by volume.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −15 to −10 °C. Jurisic's Sage is built for winter — once established it takes hard frost and snow in its stride.

It tolerates winter lows to about −15 to −10 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can jurisic's sage go outside or overwinter — and where?

It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when jurisic's sage can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H5 figure above.
