The fall color display in central Iowa has been spectacular this year. Just the right combination of warm, sunny days and cool, but above-freezing temperatures at night, along with a little stress from the driest September and October in six decades led to glorious golds, outstanding oranges, and rich reds. Yesterday’s rain and wind brought down quite a few leaves, but some trees will hold their color for a few more days, or even weeks in the case of many oaks and callery pears.
It’s odd to say that the new 950-page tome is downsized from the previous book, which is nearly 1,200 pages in length. It certainly doesn’t feel less hefty! With the inclusion of so many photos, Dirr had to leave out some of the nerdy horticultural details found in his previous work. For example, the number of red maples and hybrids discussed in the new book is 17 compared to 58 in the previous book. Similarly ginkgo dropped from 40 to 5 varieties, and dawn redwood decreased from 9 to 6 varieties. However, the book is still replete with Dirr’s personal anecdotes and observations. He has updated the book with more recent introductions and dropped some of the more obscure ones. The pictorial displays more than make up for the abbreviated text. And most gardeners will appreciate not having to sift through obscure varieties that they’re not likely to find at the local nursery anyway.
Today’s post is in honor of Love a Tree Day, which happens on May 16th every year. (Who knew?) I would write about my favorite tree, but that’s like asking a parent to choose a favorite child. I have dozens of favorites.
With ash trees under attack by emerald ash borer, American elms barely hanging on against Dutch elm disease, and American chestnuts all but wiped out by chestnut blight, I feel that it’s important to create diversity by planting a wide variety of trees.
I’ve taken that to heart in my own landscape. On my half-acre lot I have planted the following trees: a callery pear, a serviceberry, five Alberta spruces, three Austrian pines, three Eastern white pines, a sweetbay magnolia, a Japanese tree lilac, a goldenrain tree, five arborvitaes, eight upright junipers, a dawn redwood, a Vanderwolf limber pine, a black gum, a blue Colorado spruce, a red maple, a weeping European beech, an Eastern redbud, a shingle oak, a ginkgo, a Swiss stone pine, a kousa dogwood, and I’ve allowed a squirrel-seeded bur oak to grow in one of the perennial beds.
I’ll admit to punishing several “problem children”. Self-seeded cottonwoods, hackberries, chokecherries, box elders, and willows are removed from my flowerbeds where they all too often take root. I also dig out sprouting black walnuts that the ambitious squirrels bury in the planting beds.
After six years of planting, I think that my lot is about full enough of trees. I still want sunny areas for growing veggies and sun-loving flowers. So from now on, new trees will have to be dwarf. I’m envisioning dwarf conifers in a new rock garden…..
