Acer rubrum, known as the Red Maple, is a stunning species native to America. The Karpick is a male variety first cultivated at the Femrite Nursery in Aurora, America in the early 1980s. It was named after Frank Karpick, who was the former City Forester of Buffalo, New York.

It was chosen for its strong central leader, narrow slender form and densely branched canopy. Its crown widens a little as it becomes established, but doesnt exceed a 5-6m width. Being a male cultivar, it does not bear flowers or fruit, making it the perfect choice for urban locations where tree litter would be an issue.

In spring, it unfolds its distinctive bright green leaves with green aqua undersides. The stalks to the leaves are deep crimson red, standing out amongst the dense crown. Come autumn, the canopy becomes ablaze with molten shades of orange and fiery reds.

This is a beautiful tree that creates striking displays when planted as a tighter, more architectural avenue. It is ideal for bringing defined interest in both urban and suburban areas. It also provides key interest when planted in parks or as a prominent feature in public open spaces Keep in mind it does not cope exceptionally well with coastal winds or salt spreading.
