Maple Summer Leaf Color: Red Cultivar, Not Stress

SE Michigan maple planted last September has reddish leaves all spring/summer (not green). Looks healthy, no leaf drop. Was green when purchased.

Likely a Red-Foliage Cultivar

Many maples have red/purple summer foliage: Japanese red maple (Acer palmatum 'atropurpureum'), 'Crimson King' Norway maple, 'Red Sunset' red maple, etc.

Action

Call nursery to confirm cultivar.
If healthy and holding leaves, enjoy the color—it's genetic, not stress.

Nursery tag or receipt should have cultivar name.
