Pinus strobus 'Mini Twists' / Mini Twists eastern white pine
Pinus strobus 'Mini Twists' is a compact, globose to broadly pyramidal dwarf selection of eastern white pine. Needles are light bluish-green, soft and twisted about the stem. Branching and stem structure is species-typical but much slower, only growing 2 to 4 inches (5 - 10 cm) annually, resulting in a nice 5 foot (1.5 m) tall tree after 10 years. Its tidy, uniform growth and unique foliage makes 'Mini Twists' an excellent focal point in the conifer garden.
 
Origin:
This cultivar originated as a seedling selected around 2005 by Greg Williams of Wolcott, Vermont, USA. The seed parent was Pinus strobus 'Horsham,' which was planted in the vicinity of a large Pinus strobus 'Torulosa,' the apparent pollen parent. Bob Fincham of Coenosium gardens named and introduced the plant to the nursery trade.
