Hamamelis "witchhazel" is a deciduous speciman tree or small shrub 10 to 15 feet tall and wide with a vase like shape and is native in the eastern and central part of the United States. Native Americans used the leaves and bark of the Hamamelis for medicinal purposes and are also used today as an astringent for acne and other skin applications.
Two gardens in the Philadelphia region with large collections of Hamamelis are Scott Arboreum (2011 Scott Arboretum Blog on Hamamelis) and Morris Arboreum.... Plant Collection.

Roxborough HS Rain Garden – Alyssa Van Alstine
This blog is long overdue, as this project was completed in June; however, giving birth to my daughter in July sort of put a hold on things. Three of my AP Environmental Science students from Roxborough High School installed a rain garden as part of their Senior Project. The students became interested in rain gardens after learning about rainwater management in urban areas and how this relates to both surface and groundwater pollution. To learn specifics about rain gardens and rain garden installation, the students attended a 2-day Rutgers University short course. Previous blog on classes
The actual garden installation took place over the course of one unseasonably warm day in May, and was a quite laborious process. The students cleared the very sizable garden area by hand, digging out the top 6 inches of topsoil from the garden location. They then mulched the entire area, as well as dug out inlets for the water to flow before planting the native plant plugs.
Overall, this was a very time consuming yet awesome project. The students were happy to fulfill the requirements for their Senior Project, yet satisfied to leave a legacy at RHS by way of their rain garden. It was a gratifying and educational experience for us all.
