Pinus banksiana 'Angell' #2 is an upright, dwarf cultivar of jack pine with an irregular, sprawling growth habit, slightly twisted branchlets, and nice kelly-green needles that are somewhat shorter than those typical of the species. Rate of growth is 2 to 3 inches (5 - 7.5 cm) per year, more outward than upward. With a great deal of effort, 'Angell' can be trained into an upright form, but it's likely that a stake would need to be a permanent feature to achieve the effect.
This cultivar originated as a witch's broom found by Jerry Morris of Lakewood Colorado. In his field notes, Jerry described it as a "good looking broom, 3 feet tall and wide, 20 feet up in the parent tree." Upon collection, he assigned it the provisional name, Pinus banksiana [#2]. It is very often seen listed simply as 'Angel.' Given the unique spelling, one can speculate that the original broom was found in the vicinity of Angell Ranch which is southwest of Denver, Colorado.
