Native Plants: Cultivating a Sustainable Future
The US National Arboretum in Washington, D.C., is presenting a one-day symposium on native plants on Saturday, March 25, 2006, from 8:30 a.m. to 3:30 p.m. at the Arboretum's Administration Building, 3501 New York Avenue NE. The program brings together thought-provoking topics concerning the natural world and our human attempts to be a positive presence in nature's garden. The day's speakers will address our understanding of what is, and is not, native; the conditions under which natural diversity flourishes, and how our personal landscapes can be transformed from mere ornamental spaces to become genuine environmental assets. Symposium participants can also shop at the Arboretum's Native Plant Sale. For program brochure, fees, and symposium registration, call (202) 245-5898, or visit: http://www.usna.usda.gov
Hydrangea Questions and Answers
In recent years, hydrangeas have become some of the most popular shrubs for the landscape, with dozens of new cultivars introduced. Unfortunately, gardeners are not always successful in growing them. To better understand what it takes to grow hydrangeas, the U.S. National Arboretum provides a Hydrangea Questions and Answers Web site. Some of the topics covered include the types of hydrangeas, where to purchase, where to plant, why hydrangeas don't bloom, how to get them to bloom, how to change flower color, how and when to prune, controlling pests, and how to dry the flowers.
