Signs of spring are beginning to pop up if you look close enough. In the last week or so, I’ve noticed harbinger of spring (Erigenia bulbosa) and spring beauties (Claytonia virginica) in natural areas. The beginnings of Virginia bluebells can also be found as their distinctly purple-blue new leaves poke up in more protected locations on the forest floor or in garden beds.
Daffodils (Narcissus spp.) and other non-native bulbs are up with flowers developing on plants in...
On a sunny and cold day in early February, some Urbana residents helped to spread handfuls of native prairie seed on the ground. Using tools as simple as a paper cup or their bare hands, the seeds were broadcast into the air, falling silently to the ground.

Pruning is perhaps the most important landscape maintenance task performed in any space that hosts woody plants. There is a large list of benefits to plant health, which is the most important reason to prune, but it’s often essential to prune woody plants so they maintain the form and structure we expect.
Dormancy is the best time for pruning because it has the...
Across the United States, our urban and natural forest ecosystems support a wide range of both flora and fauna. Trees are certainly the center of these plant communities and remain the most symbolic and recognized plant life on the landscape.
Have you ever wondered exactly how many native species are native to our state, or even our country?
Filling a Gap
A recent research collaboration between Morton Arboretum and others sought to address many of these questions. These...
Extreme winter cold is something that can keep gardeners up at night. Since plants are dormant, there is little we can do in the way of plant health care and that can be a real helpless feeling. The extremely cold weather back in December certainly raised concern and my office received a number of calls from worried gardeners.

To put our recent cold snap in perspective, it helps to consider the United States Department of Agriculture (USDA) Cold...
