Here is another nifty mag I pilfer at work - again, strictly in the interest of knowledge! As opposed to Fine Gardening, Hort offers information on what's hot and what's not. They too have a very informative Q&A section.
Hort is usually dedicated to the new plants and ideas available for the season. They offer informative descriptions of the plant and all related subspecies as well as planting and maintenance guides. They also offer a large section showing upcoming garden and nursery tours, both stateside and overseas.
Their articles are mainly focused on the how-to and why-to whereas Fine Gardening is more personal. I love the combination...
