The Midwest has several good ones to choose from, each teaching you a bit about bringing various landscapes to your own property and how to better understand those plantings. And beyond Minnesota's own top-shelf arboretum, which charges a timed admission fee for nonmembers, most of the other Midwestern facilities below are free to roam in.
So let's road-trip to some favorite outdoor classrooms and celebrate the colors of nature.
Minnesota Landscape Arboretum
First up, closest to home is the 1,200 acres of the Landscape Arboretum in Chaska, managed by the University of Minnesota. Dating to 1958, the original mission of "The Arb" was to develop plants and trees that can survive Minnesota winters.
As a result, pines are dominant here, with more than 200 specimens. But the conifers don't turn colors, so look for the Buckeye Collection. Although the deciduous buckeye is not native to Minnesota, it is among the first to turn bright yellow and orange.
Find these and much more along Three-Mile Drive, the self-guided driving route that links most of the Arb's diverse sections. You may drive your own vehicle, take a tram, or ride a bike and learn at your leisure. Master Gardeners are available on Saturdays in the library to answer questions. (8 a.m.-7 p.m. daily. 3675 Arboretum Drive, Chaska. Timed reservations $15 for ages 16 & older; arb.umn.edu.)
University of Wisconsin-Madison Arboretum
The red-maroon tree blazing in front of this arboretum's visitor center is nicknamed Carolyn, after former curator Ed Hasselkus' granddaughter. It's actually a black tupelo that was planted in 1961.
The Badger State's magnificent arboretum, known for exemplary restoration ecology and conservation, is a National Historic Landmark. Explore the woodlands, which glow yellow with basswoods and sugar maples, along 17 miles of trails through more than 1,200 acres. If you have time for only one highlight, make sure to visit the Longenecker Horticultural Gardens. A guided fall color hike ($25) is scheduled for Oct. 16, expected to be peak color time in Madison (arboretum.wisc.edu).
Iowa Arboretum
Plan on a trip to Madrid, in central Iowa, on Oct. 11 or 18 for an in-depth walking tour of the Iowa Arboretum, 160 acres of woodland set in the Des Moines River Valley. Curator David McKinney will explain what trees and other plants make for the best fall show in your own lawn and garden.
