About Serbian Spruce 'Pendula'

Picea omorika 'Pendula' · also called weeping Serbian spruce · flowering

This weeping cultivar of Serbian spruce forms a dramatically narrow, almost vertical column with strongly cascading branches that hug the trunk, draping in silver-backed dark green needles. A living sculpture for tight spaces, it shares the species' tolerance of pollution, clay and chalk, needing only full sun and free-draining soil to become a striking architectural specimen.

Cold limit: USDA 4-7 · RHS H7 (-30 to 25°C)

Watch for — Green spruce aphid: Spring or mild-winter feeding mottles and sheds older needles, thinning the cascade; inspect interior foliage early and treat before defoliation progresses.
