Pinus parviflora 'Catherine Elizabeth' starts out as a dwarf, irregular-globose selection of Japanese white pine; that, with age, will "open up" assuming more of a sculpted, wind-swept structure. Foliage is more-or-less species typical, although perhaps a little shorter and occasionally growing with a slight twist. After 10 years of growth, a mature specimen will measure 16 inches (40 cm) tall and 24 inches (60 cm) wide, an annual growth rate of 1.5 to 2 inches (4 - 6 cm).
This cultivar was one of many seedlings, grown and selected in 1980s and 1990s by John Proudfoot of Methven, Scotland, United Kingdom. Like all of his selections, this conifer began its existence with a code name. In this case, it's provisional designation was [M-par 21].
Catherine Elizabeth is one of seven selections made in 2019 for the popular ACS Collectors' Conifer of the Year Program.
