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.
