feet. Ornamental Attributes: Dark, rusty-colored buds, very large white flower clusters, brilliant red fall color, dark blocky bark. “Simply gorgeous any time of the year.”90 Tolerates black walnut tree toxicity. Zones: 5–8; SQUASHBERRY, MOOSEWOOD VIBURNUM, LOWBUSH CRANBERRY (V. edule). Height: 2–7 feet. Ornamental Attributes: A northern shrub with showy flowers; yellow fruit turns red or orange in late fall and makes good jam. Note: Threatened or endangered in parts of the Midwest. Zones: 3–5; WITHEROD (V. nudum var. cassinoides). Height: 5–8 feet. Ornamental Attributes: Domed clusters of creamy-white flowers in June; colors of serially ripening fruits range from pink, yellow, red, and powdery blue to black. Long-lasting fall color ranges from orange to purple; exfoliating bark. Cultivation: Full sun to part shade; wet, acidic soil; also found in drier sites. Note: Endangered in parts of the Midwest. Zones: 3–9. Viburnum Nature Note: Native viburnum flowers attract pollinators such as the red-spotted purple (p. 18) and other butterflies, Peck’s skipper (p. 135) and other skipper butterflies, hummingbird moths (p. 72), bees, dance flies, wasps, ants, and beetles; have special value to native bees and can be used as part of conservation biological control. Viburnums host 104 Lepidoptera species (butterflies/moths), including Baltimore checkerspot, Henry’s elfin (p. 93), spring azure (p. 95), and sphinx moths, hummingbird clearwing moth (p. 72), and the rose hooktip moth, a New World viburnum specialist. Baltimore butterfly caterpillars sometimes move off their host plants (false foxglove species) to feed on viburnum leaves. Butterfly and moth caterpillars are important food for birds and their offspring. Native viburnum species fruits attract at least 35 bird species, including many warblers, flycatchers, vireos, eastern bluebird (p. 61), wood thrush (p. 175), American robin (p. 62), northern mockingbird (p. 256), gray catbird (p. 79), cedar waxwing (p. 36), northern cardinal (p. 61), blue jay (p. 79), common redpoll (p. 54), and grosbeaks (pp. 162, 200). Fruit with high fat and carbohydrate content is crucial to birds battling cold temperatures where insects are not available and to migratory birds, which need sustenance for their long flights. At the top of the bird berry menu is northern bayberry (see Fall Shrubs, p. 232), with slightly over 50 percent fat; arrowwood viburnum (V. dentatum) is second, with 41.3 percent fat content. (The vine Virginia creeper (Parthenocissus quinquefolia) has 23.6 percent fat content.)91 Mapleleaf viburnum berries’ high sugar content makes them winter persistent and thus a very important food source for a wide variety of birds in the winter.92 Small mammals and Bell’s vireo and other birds seek the shrubs for cover and nesting.
