Pinus flexilis 'Cesarini Blue' is a slow-growing, narrow, upright selection of limber pine with compact branching and long, powder-blue needles. After 10 years of growth, a mature specimen will measure 7.5 feet (2.5 m) tall and 40 inches (1 m) wide, an annual growth rate of 6 to 8 inches (15 - 20 cm).
This cultivar originated as a seedling selected and named for noted plantsman, Joe Cesarini of Ridgely, Maryland. Similar cultivar names exist for P. peuce and strobus in violation of nomenclature rules that allow a specific cultivar name to be used only once within a single genus.
