Acer saccharum 'Newton Sentry'

Found in 1885 at the entrance to the Newton, MA cemetery. This is said to be the most upright of any maple. Will get 30' x 2' in many years. The deep green leaves turn yellow-orange in fall.

An introduction from the mid 1800's first described as ''Towering shafts of foliage'' this sugar maple has an upright columnar form with several leaders reaching skyward especially as it matures. The height is approximately 4 times the width of the tree and major and minor branches are vertical. Acer saccharum 'Monumentale' tends to have a strong central leader in contrast to the multiple leaders of 'Newton Sentry' that start branching out about 6 feet from the ground.Minimum temperature: -30° F

Described by F.L. Temple as "exhibiting towering shafts of foliage" - heavily contrasting the spreading habit of the species. This tree is about 3' wide when 30' tall, unbelievably narrow. This is likely the same variety as 'Temple's Upright' and there is some confusion between this variety and 'Monumentale' - both of which are unbelievably narrow. 'Newton Sentry' has major and minor vertical branches with short, stubby lateral branches - in sum, this trees is incredible, and although it has been around since the 1860's it is RARELY seen as it is very difficult to propagate. A necessity in any serious collection.
