Pinus flexilis 'Glauca Pendula' / blue weeping limber pine
Pinus flexilis 'Glauca Pendula' is an amorphous, spreading selection of limber pine that really puts the flexible into flexilis. Weak central leaders tend to bend over under their own weight; irregular branching is equally unpredictable; and branchlets tend to be fully weeping or pendant. No two trees will be alike. Given the unpredictable nature of this conifer, 10-year metrics are hard to predict. Terminal buds extend up to 12 inches (30 cm) annually, putting this plant into the large category of growth.
This cultivar originated in the United Kingdom sometime in the 1970s. Hillier & Sons Nursery, or Winchester, United Kingdom is thought to have introduced it to the European market, while in the U.S. it is thought to have been introduced by John Vermeulen Nursery of Neshanic Station, New Jersey, and propagated from a specimen in the Gotelli Collection at the U.S. National Arboretum in Washington, DC.
