You may have noticed the glowing red tree tops dotting our landscape. What you are most likely looking at are the flowers of the Red Maple (Acer rubrum) tree. One of the earliest trees to come into bloom, the flowers are so tiny that they are often overlooked.

There are countless ways in which this extraordinary tree gives life. Being one of the first trees to bloom in the spring, it is a potent source of nectar for early bees on the wing. Little warblers, like this female Common Yellowthroat, find tiny spiders, insects, and larvae that are attracted to the pollen and nectar found amidst the tree’s blossoms.
Following the tree’s flowering period, pink and green two-toned winged fruits form. Officially called samaras, we mostly know them by self-describing names like helicopters and whirligigs. The wind blows the seeds far and wide where they are eaten by a great variety of birds and small mammals including turkeys, squirrels, and chipmunks.
But it is their yummy foliage that makes Red Maples a critical native keystone species. Somewhere between 200 to 300 species of Lepidoptera feed on the leaves of Red Maples including Giant Silkmoths Luna and Cecropia.

To top off the smorgasbord of food for wildlife that this beautiful tree provides, for us humans, autumn brings a gorgeous display of brilliant red foliage.
Red Maples are also called Swamp Maples but that doesn’t mean they only grow in swampy, super wet environments. Red Maples will tolerate average garden soil, just not super dry conditions. Grown in well-drained, loamy and acidic soil, they will thrive. Red Maples are the fastest growing tree in the Eastern US. They may reach a height to 70 feet in the Northeast, adding about 18 inches in height per year. When properly cared for, Red Maples can live up to 100 years.
