Plant list

The Arboretum is an excellent reference collection with both commonly cultivated and rare species.

The largest family group by species is the rose family (Rosaceae), which includes familiar horticultural plants such as rose, potentilla, spiraea, crabapple, hawthorn, plum, cherry, mountainash, and cotoneaster.

The second largest group are the pine family (Pinaceae), with pine, spruce, larch, fir, Douglas fir and hemlock. This is followed by another large group, the cypress family (Cupressaceae) containing juniper, arborvitae (Thuja), Microbiota and Chamaecyparis. Other large groups include the honeysuckle family (Caprifoliaceae) and the soapberry family (Sapindaceae) containing maple (formerly in Aceraceae) and buckeye.

The collection includes many species of oak, birch, walnut, linden, ash, willow, poplar, sumac, catalpa, euonymus, buckthorn, dogwood, currant, and clematis.

Cultivars and selections are best represented in the lilacs (Syringa), followed by roses and juniper. There are also many cultivars of crabapple, eastern white cedar (Thuja occidentalis), and potentilla.
