Located at the crossroads of the United States, the University of Illinois's well-regarded Extension division has provided outreach services to the state's residents for over a century. For over a decade, they have also provided assistance to both residents of the state and a diverse set of interested parties from all over the world via their visually attractive website. One of their sites is dedicated to providing information about horticulture, with specific sections on plant propagation, urban agriculture, and composting. Colorful photographs on the horticulture homepage will deliver visitors to brief and well-written treatises on "Selecting Trees for Your Home", "Composting for the Homeowner", and "Gardening with Perennials". Those persons interested in instructing fellow horticulturalists and neophyte gardeners in the fine art of vegetative propagation will want to click on over to the "Houseplants" area which addresses this topic in detail.
