This new UNL Plants blog is up and running. The information provided is designed to supplement the HORT 214/Herbaceous Landscape Plants class at the University of Nebraska-Lincoln.
The links along the left side of the page are pretty self explanatory and follow along with the class schedule.
The various links to other websites are good resources to use when searching for information on plants not discussed in this course.
