Collins Nursery, in Glenside, PA, propagates native trees, shrubs and perennials from local seeds. Two years ago, I was looking for Pawpaw trees because I read that you need more than one to get fruit and I had only one. Collins Nursery is open by appointment and has two open houses each year, so I called and made an appointment. Diane Ehrich is the nursery manager. I came home with seven Viburnum ( three acerifolium, and one each of dentate, nudum, prunifolium, and trillium ), one Cornus florida, four Ilex glabra, one Pinus strobes, one Tsuga canadensis, and three Asimina trilby in my small station wagen.

Some of the viburnums: Cranberry, Blackhaw, and Maple.
Some of the trees: Dogwood, Pawpaw, and Hemlock.
