Taxus x media 'Hatfieldii' · also called Hatfield's Yew, Upright Yew · flowering

Cold limit: USDA 4-7 (outdoor landscape shrub) · RHS H6 (-29 to 30°C)

Watch for — Winter desiccation: Exposed plants brown on windward foliage in cold, dry winters. Shelter from winter wind and water thoroughly before freeze-up.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −20 to −15 °C. Hatfieldii Yew is built for winter — once established it takes hard frost and snow in its stride.

It tolerates winter lows to about −20 to −15 °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 hatfieldii yew go outside or overwinter — and where?

Plant it out within USDA 4-7 (outdoor landscape shrub) 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 hatfieldii yew can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H6 figure above.
