Northwind Maple Information

Jack Frost maple trees are crosses between Japanese maples (Acer palmatum) and Korean maples (Acer pseudosieboldianum). They have the beauty of the Japanese maple parent, but the Korean maple’s cold tolerance. They were developed to be extremely cold-hardy. These Jack Frost maple trees thrive in USDA zone 4 in temperatures down to -30 degrees F. (-34 C.).

The official cultivar name for Jack Frost maple trees is NORTH WIND® maple. The scientific name is Acer x pseudosieboldianum. These trees can be expected to live for 60 years or more.

The Northwind Japanese maple is a small tree that usually doesn’t get taller than 20 feet (6 m.). Unlike its Japanese maple parent, this maple can survive into zone 4a without any signs of dieback.

Northwind Japanese maples are truly lovely little deciduous trees. They add color charm to any garden, no matter how small. The maple leaves appear in spring a brilliant orange-red. They mature into light green, then blaze into crimson in the autumn.
