In case you missed it, autumn is officially here. Some tree species seem to get the memo sooner than others; Callery pear, Liquidambar, Chinese pistachio and one of my favorites, American ash (the aptly named 'Autumn Purple' cultivar is pictured here) are already showing their true colors.
Among shrubs, you'll start seeing autumn colors soon on heavenly bamboo and viburnums; and some grasses such as 'Haense Herms' switchgrass are equally brilliant.
I'm not saying these are necessarily the best plants for fall color, just some of the earliest. If you like autumn to be a season in your garden, not just a page in your calendar, they're worth a look.
What are some of your fall favorites?
