Pinus strobus 'Nana' is a dwarf, globose selection of eastern white pine that will eventually become broadly conical with age. Branching is symmetrical, radiating upward and outward; and needles are fluffy, blue-green in color, and somewhat shorter than what's typically seen in the species. After 10 years of growth, a mature specimen will measure 6 feet (2 m) tall and wide, an annual growth rate of 6 to 8 inches (15 - 20 cm).
'Nana' translates into dwarf fro the Latin language.
This cultivar was first described by Élie-Abel Carrière in Traite General des Coniferes. In 1891, Ludwig Beissner, in Handbuch der Nadelhölzkunde, said that 'Nana' is synonymous with Pinus strobus var. brevifolia and var. compressa. The World Checklist of Conifers (Humphrey Welch, 1993) states that the cultivar name 'Nana' is a botanical designation for several slow-growing clones that never exceed 10 feet (3 m) tall. It goes on to describe "a name in use for several clones of the past." For this reason, 'Nana' should no long be considered as a legitimate cultivar name.
