Picea abies 'Clanbrassiliana Stricta' is a dwarf selection of Norway spruce that bears some passing resemblance to P. abies 'Clanbrassiliana', but is more conical in structure and has a more fastigiate habit in its terminal shoots. It can be further described as quick-growing, broadly pyramidal with rich, bright-green foliage. After 10 years of growth a specimen can be considered mature at 4 feet (1.2 m) tall and 2 feet (60 cm) wide, an annual growth rate of 4 to 5 inches (10 - 12.5 cm).
This cultivar originated in the late 1780s, likely found in the wild in Florence Court, County Fermanagh, Northern Ireland. by Lord Clanbrassil, Tollymore, Country Down, Northern Ireland. It is one of three cultivars more-or-less named in his honor. In the Latin language, Clanbrassiliana Stricta translates into "Lord Clanbrassil's Stiff and Erect Norway spruce."
