Pinus strobus ‘Radiata’

Pinus strobus 'Radiata' is a slow growing, globose dwarf selection of eastern white pine that will eventually become broadly conical with age. Blue-green needles tend to grow at variable lengths throughout the plant. After 10 years of growth, a mature specimen will measure 28 inches (70 cm) tall and 40 inches (1 m) wide, an annual growth rate of 3 to 4 inches (7.5 - 10 cm).

[ Humphrey Welch and Gordon Haddow in The World Checklist of Conifers ] .., a 1923 clone distinguished by Hornibrook from Nana in 1923 and still widely planted. It makes a plant wider than high; densely clothed with slender twigs and long bluish leaves.

This cultivar originated in the early 1920s, presumably in Europe. Murray Hornibrook first described and named it in his 1923 book, Dwarf and Slow-growing Conifers.
