About Standishii Yew

Taxus baccata 'Standishii' · also called Standish's Golden Yew, Columnar Golden Yew · flowering

Standish's Golden Yew is a slow, narrowly columnar English yew with golden-yellow foliage that glows in light shade and brightens to richer gold in sun. Compact enough for small gardens, it makes a refined vertical accent. Sharp drainage is essential. All parts except the red aril are highly toxic to pets and people.

Cold limit: USDA 6-7 (outdoor landscape shrub) · RHS H6 (-23 to 30°C)

Watch for — Winter and sun scorch: Gold foliage can scorch in intense reflected heat or dry winter wind. Balance enough sun for color against shelter from extremes.

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 standishii yew 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.
