Pinus sylvestris 'Watereri' is a small, upright, slow growing, broadly conical selection of Scots pine with thick, fleshy, stiff, blue-gray needles. 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).
This cultivar originated as a unique small tree, found in the early 1860s, on Horsell Common, Surrey, United Kingdom. Anthony Waterer Sr. (1745 - 1827), founder of Knap Hill Nursery, assumed the naming rights for this conifer. It is reported that the original tree still exists on the grounds of Knap Hill Nursery, Woking, Surrey, UK.
Ludwig Beissner first formally described this conifer in 1891 in Handbuch der Nadelhölzekunde. Welch and Haddow in The World Checklist of Conifers mentions the superfluous synonyms, 'Watereriana', 'Nana', and 'Pumila'.
