Click here to view the Connecticut Native Tree and Shrub Availability List which cross-references native species with nurseries where they are available. This list was produced by the Connecticut DEP, Bureau of Natural Resources, Wildlife division. Hay-scented fern (Dennstaedtia punctilobula): Attractive, delicate, yellow-green fern, tolerant of dry, sunny openings. Sensitive fern (Onoclea sensibilis) : Typical of wet spots. After the first frost the interesting brown bead-like stalks of the fertilefronds stand out strikingly. Cinnamon fern (Osmunda cinnamomea) : Charachteristic of wet, swampy areas. A large fern found in clumps with tan cinnamon-like fuzz on the fronds. Fertile frond is a seperate tan-colored stalk providing spores. Interrupted fern (Osmunda claytoniana) : Similar in habit and general appearance to the cinnamon fern except for a distinctive interruption in the frond by several spore-bearing leaflets. New York fern (Dryopteris noveboracensis) : A small, light green fern loving moist situations, with fronds that taper to a point at both ends.
Red top (Agrostis alba) : A fine, delicate, perrenial grass of great beauty, found in open fields. Little bluestem (Schizachyrium scoparium) : Late summer maturing, tussock-forming grass with striking yellowish-tan winter tones. Typical of dry fields. Periodic burning increases vigor and beauty as shown from Arboretum research on prescribed burning. Fire breaks are needed where there are sizable stands, since it is a fire type. Sweet vernal grass (Anthoxanthum odoratum) : Spring flowering, sweet-smelling grass of old fields. Native of Eurasia. Pennsylvania sedge (Carex pensylvanica) : Low growing, 3-ranked, yellow-green grass-like tufts of leaves. May develop in open, dry woods, especially on dry, sunny slopes or in fields.

Tolerates poor soils and provides good cover for wildlife. Bush honeysuckle (Diervilla lonicera) : Yellow to reddish flowers. Huckleberry (Gaylussacia baccata) : One of the most brilliant autumn shrubs in the Arboretumn, exibiting remarkable stability in arresting tree establishment.

Chokeberry (Pyrus arbutifolia, P. melanocarpa): Clonal spiecies with shiny, dark green leaves and white rosaceaous flowers, Reddish-orange autumn color. Great laurel (Rhododendron maximum): Large broad-leaved evergreen that will whithstand forest shade. Ideal planting for winter contrast. Large masses of white flowers in early July. Azaleas (Rhododendron nudiflorum, R. viscosum): Spectacular pink woodland azalea or pinxter flower (R. nudiflorum) which transplants easily and should be and should be used more frequently in naturalistic landscaping. In wetter spots the clammy azalea (R. viscosum) is an extremely fragrant flowering shrub. Sumacs (Rhus glabra, R. copallina): Several species of sumac occur as clones in abandoned fields. They exibit a striking red autumn color but may crowd out the more desirable species, especially grasses and forbes. The smooth sumac (R. glabra) produces the most striking red fruiting clusters. Bristly locust (Robinia hispida): Clonal habit, producing beautiful pendulous clusters of pink flowers in spring. Excellent for dry sites. Roses (Rosa rugosa): The shore rose is typical along sand dunes and is tolerant of salt spray. Beware of the multiflora rose (Rosa multiflora) as it is a very agressive introduced exotic which is very difficult to conrtol. Blackberries (Rubus spp.): These are usually considered undesirable. However, they can yield fruit and have high wildlife food and cover value. Pussy willow (Salix discolor): The opening of the gray, wooly catkins is another signal of spring on your homegrounds. Highbush blueberry (Vaccinium corymbosum): A shrub with striking autumn coloration in our naturalistic landscape area. Viburnums (Viburnum lentago, V. prunifolium, V. cassinoides, V. alnifolium, V. recognitum, V. opulus): A large group of flowering shrubs with high cover and wildlife value.
