Tree of the Month - April 2017

Right now every plant feels like it is flowering and the trees are at full flower strength too, Spring frolicking isn’t just for the birds and the bees. Much of that chartreuse green we see on the trees all over is not the expected new green leaves, so much as the tree flowers. There are, of course, the beautiful showy flowers of the Magnolias, Crabs, Redbuds, and Callery Pears that we love. But the less showy flowers that are bright green and sometimes less vibrant hues of pink or yellow are also in abundance this time of year.

In Northern Illinois the dominant species, the king of the prairie, remains the giant Burr Oak. Standing strong where most trees fail. You can see it on hill tops and out crops from Chicago to Rockford and all the way through Iowa. Burr Oak still grows down south but it becomes far less prominent, while the Red and Shingle Oak, Sweet Gum, Red Maple and of course Sycamore are the trees we notice at 60 MPH.

The Flowering Dogwood, in October, was in burgundy fall color taking over the understory. In May before the big trees foliate, when the Dogwoods and Redbuds dress the forest in white and pink lace it is wonderful to behold the Tennessee and Kentucky woods. Though it is one of the best known flowering trees in the country I’d never even seen a flowering Dogwood until I was 17, when I left Illinois.
