Walk through a rich, moist eastern hardwood forest in late June or early July. Look up and you will find it: a massive, broad-crowned tree carrying thousands of small, cream-colored flowers, every one of them buzzing with bees. Undoubtedly that is a basswood tree (Tilia americana) The basswood tree is one of eastern North America’s…
If you have ever driven past a row of tall, silver-blue conifers standing like sentinels along a fence line, there is a good chance you were looking at Blue Ice Arizona Cypress. This tree has quietly become one of the most popular ornamental conifers in North American. I have seen many evergreen trees come and…
If you have ever walked through a snow-dusted northern forest in December and inhaled that unmistakable, sweet, clean scent of pine — sharp and resinous and somehow comforting at the same time — there is a very good chance you were smelling balsam fir. Few trees carry as much sensory identity as Abies balsamea. Its…
There are trees that fill a garden. Then there are trees that fill a skyline. Douglas fir (Pseudotsuga menziesii) belongs firmly to the second category. I have stood at the base of old-growth Douglas firs in the Pacific Northwest, craning my neck upward and still not seeing the canopy. These trees do not merely grow…

The Weeping Eastern White Pine, with its long, soft needles cascading downward like green curtains and its irregular, sweeping silhouette, brings a rare kind of quiet drama to any landscape. It is one of those plants that, once you see it in a well-designed garden, you simply cannot forget. I have seen this tree used…
There is something quietly magical about a Yoshino cherry tree in full bloom. Every spring, the tree erupts in a soft cloud of white and pale pink blossoms — a sight so striking that thousands travel to Washington, D.C., just to witness it. But beauty is only one side of the story. Before you plant…
Arizona contains four distinct desert regions, each with its own climate, elevation, and plant community. The Sonoran Desert — covering much of southern and central Arizona including the Phoenix and Tucson metro areas — is the hottest and most biologically diverse of the four. That two-season rainfall pattern — typically totaling 3 to 12 inches…
Eucalyptus trees are native to Australia, Tasmania, and nearby islands, where they comprise the dominant tree genus across most of the continent. Of approximately 700 species in the genus, none is native to the Americas. The story of how eucalyptus arrived in California begins in the Gold Rush era of the 1850s, when Australian ships…
The northern red oak (Quercus rubra) is one of the most widely planted and ecologically important native trees in North America. It is fast-growing for an oak, brilliantly colored in autumn, and capable of supporting more forms of wildlife than almost any other tree on the continent. But it is not without its challenges. It…
