Pinus sylvestris beauvronensis, USDA H3-hardy
A very old cv: globose slow growing, densely branched dwarfish shrub with blue-green needles, according to season and planting. 60x60cm in 10 yrs, though some very old specimens have reached 4-5m(so not that dwarf really). Originates since before 1891 from a witches’ broom.
