Sequoia sempervirens 'Adpressa' / Dwarf Redwood

'Adpressa' is characterized by creamy white, tightly-held needles. Left unattended, it will form a broadly conical, somewhat open tree. However, if subjected to regular shearing, 'Adpressa' will be a fairly tight, bright white ball.

Photo taken at Glacier's End Arboretum in Olympia, WA in 2011. This specimen shows the structure resulting from regular coppicing.
