About Laurustinus Viburnum

Viburnum tinus · also called Laurustinus · flowering

Laurustinus is a dense, evergreen Mediterranean shrub valued for flowering through autumn and winter, when pink buds open to flat clusters of small white flowers above glossy dark-green leaves. Metallic blue-black berries follow. Tough, shade-tolerant, and excellent for hedging or screening, it thrives in full sun to part shade in well-drained soil and tolerates coastal and urban conditions.

Cold limit: USDA 8-10 · RHS H4 (-12 to 35°C)

Watch for — Viburnum beetle: Larvae shred leaves to a lacy skeleton in late spring, with adults feeding later. Inspect undersides of leaves, prune out egg-laid twigs in winter, and treat only heavy attacks.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −10 to −5 °C. Laurustinus Viburnum is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for laurustinus viburnum as it gets too cold:

It tolerates winter lows to about −10 to −5 °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 laurustinus viburnum go outside or overwinter — and where?

Plant it out within USDA 8-10 and it overwinters with little or no help.
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 laurustinus viburnum can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H4 figure above.
