  • Disease and Insect Resistant Ornamental Plants: Viburnum
    nysipm.cornell.edu 2018 hdl.handle.net/1813/56379 Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University VIBURNUM Viburnum pixabay.com Viburnum is a genus of about 150 species of de- ciduous, evergreen and semi-evergreen shrubs or small trees. Widely used in landscape plantings, these versatile plants offer diverse foliage, color- ful fruit and attractive flowers. Viburnums are relatively pest-free, but in some parts of the US the viburnum leaf beetle can be a serious pest in both landscape and natural settings. Potential diseases include bacterial leaf spot and powdery mildew. INSECTS Viburnum Leaf Beetle, Pyrrhalta viburni, is a leaf-feeding insect native to Europe and Asia. In North America, the beetle became established around Ottawa, Canada in the 1970’s and was first detected in the United States in Maine in 1994 and in New York in 1996. It has since spread through much of the northeastern US (15). Reports of viburnum leaf beetle in the Midwest include Ohio, Michigan, Wisconsin and Illinois (1) and Washington and British Columbia, Canada in the Pacific Northwest (7). The beetle is host-specific and feeds only on Viburnum, but there are preferences within the genus (6). Species with thick leaves tend to be more resistant and feeding is more likely to occur on plants grown in the shade (17). Feeding by both larvae and adults causes tattered leaves and may result in extensive defoliation – repeated defoliations can kill the plant.

  • Maple-Leaf Viburnum (Viburnum Acerifolium)
    Information Sheet – Maple-leaf Viburnum (Viburnum acerifolium) Maple-leaf Viburnum (Viburnum acerifolium) is a low, densely branched shrub that grows to 4-6 feet tall and 3-4 feet wide. This attractive native shrub is often planted as an ornamental due to its bright to dark green, deciduous foliage that turns a colorful purplish-pink in the fall. In addition, showy flat-topped clusters of white flowers in spring are followed by blue-black berries in the late summer and fall. Maple-leaf Viburnum is adaptable to a wide range of light and soil conditions. This adaptability makes it a useful plant in home landscapes that have areas with dry soil and deep shade. This outstanding native shrub is also often planted for its high wildlife value – its berries are eaten by birds and its flowers are nectar sources for bees and butterflies. This plant is also a larval host to several butterfly and moth species, to include the Spring Azure. Care of your shrub or small tree: It is important to get your shrub off to a good start by planting it properly in accordance with the instructions on the reverses of this sheet. After planting, maintain a grass and weed-free area around the base of the young shrub. Use organic mulch around the base of the trees approximately three feet out from the trunk. Pine bark and pine needle mulches are very good, straight wood mulch is not. Avoid the use of non-organic mulches, which can cause the soil around the shrub to stay excessively wet.

  • Circumneutral Mixed Shrub Wetland System
    Circumneutral Mixed Shrub Wetland System: Palustrine Subsystem: Shrubland PA Ecological Group(s): Basin Wetland Global Rank: G4G5 State Rank: S3 General Description This shrub-dominated wetland community occurs in a variety of palustrine settings, including the upland edge of marshes, at the wetter edge of red maple wetlands, in small upland depressions, stream floodplains, and at the base of slopes. The community may represent a successional stage between abandoned agricultural land and a forest community. The substrate is generally very poorly drained shallow peat or mineral soil with a thin organic layer. These wetlands are generally seasonally flooded and may remain saturated for much of the growing season. Nutrient enrichment is generally the result of discharge from groundwater or inflow from the surrounding watershed. The pH of these systems is broadly circumneutral to somewhat calcareous, and calciphiles may be present. Many of these wetlands were or currently are influenced by beaver activity or other impoundments. Grazing (past and present) and previous land use history (e.g., farming) may also be a factor. Community size ranges from small inclusions to extensive acreage. The community is characterized by a substantial tall-shrub layer that may be dominated by a single shrub species or a patchwork of mixed shrubs. Shrub species typically found in this community include: smooth alder (Alnus serrulata), speckled alder (A. incana ssp. rugosa), ninebark (Physocarpus opulifolius), willows (Salix spp.), American elder (Sambucus canadensis), dogwoodc (Cornus spp.), water- willow (Decodon verticillatus), buttonbush (Cephalanthus occidentalis), winterberry (Ilex verticillata), viburnum (Viburnum spp.), meadow-sweet (Spiraea spp.), and swamp rose (Rosa palustris). Scattered seedling/sapling sized trees may be present such as red maple (Acer rubrum).

Management of the Viburnum Leaf Beetle at the Morris Arboretum Abstract Pyrrhalta viburni (Coleoptera: Chrysomelidae), or the viburnum leaf beetle (VLB), is an invasive pest on viburnums in North America, where native species of the plant have little natural resistance. Resistance can be conferred by leaf texture, leaf chemistry, or a wound response that crushes VLB eggs. The beetle does not immediately kill host plants, but repeated defoliation is fatal after several years. Because viburnum is a common forest and landscape plant in the eastern United States, VLB is a serious concern. The Morris Arboretum has a large collection of viburnums, including many native and non-native species. While VLB had already been observed in passing, this project included a thorough baseline survey of VLB damage throughout the Arboretum. Data were collected for the number of twigs infested with VLB, the number of cavities on each twig, and whether a wound response had been produced.

  • Chinese Snowball Viburnum Scientific Name
    Common Name: Chinese Snowball Viburnum Scientific Name: Viburnum macrocephalum Order: Dipsacales Family: Adoxaceae Description Chinese snowball viburnum produces large 6-8 inch clusters of hydrangea-like flowers that start out as lime green and mature to white in the early spring. It can grow taller than 15 feet. It is very large, dense, and rounded with oval shaped leaves. This plant bears no fruit. This viburnum’s longevity is less than 50 years. Chinese snowball viburnum is a deciduous plant. It produces large white hydrangea- like flowers and then loses its leaves annually. This plant can be semi-evergreen in the south, and often re-blooms in the late summer or fall. Growth Habit The growth habit of the Chinese snowball viburnum is erect or spreading and has deciduous foliage, but often re-blooms in late summer or fall. It shape is rounded and grows 24 inches per season. This plant can grow to 15 feet or more in height. It can also be cut back every 3-4 years to 2-3 inches to control size if necessary, although bloom for the following year will be lost. This viburnum’s rooting resents being disturbed and should be left in place until the second year. Hardiness Zone(s) Chinese snowball viburnum can grow in the USDA zones 5 through 9. It may be grown in certain conditions in zones 4 and 8. If it is grown in zone 4 then a protected situation is recommended. Chinese snowball viburnum emerges in the early spring. It is fully heat tolerant and is very beautiful in full bloom but not as attractive the rest of the year.

  • Phylogeny and Phylogenetic Taxonomy of Dipsacales, with Special Reference to Sinadoxa and Tetradoxa (Adoxaceae)
    PHYLOGENY AND PHYLOGENETIC TAXONOMY OF DIPSACALES, WITH SPECIAL REFERENCE TO SINADOXA AND TETRADOXA (ADOXACEAE) MICHAEL J. DONOGHUE,1 TORSTEN ERIKSSON,2 PATRICK A. REEVES,3 AND RICHARD G. OLMSTEAD 3 Abstract. To further clarify phylogenetic relationships within Dipsacales,we analyzed new and previously pub- lished rbcL sequences, alone and in combination with morphological data. We also examined relationships within Adoxaceae using rbcL and nuclear ribosomal internal transcribed spacer (ITS) sequences. We conclude from these analyses that Dipsacales comprise two major lineages:Adoxaceae and Caprifoliaceae (sensu Judd et al.,1994), which both contain elements of traditional Caprifoliaceae.Within Adoxaceae, the following relation- ships are strongly supported: (Viburnum (Sambucus (Sinadoxa (Tetradoxa, Adoxa)))). Combined analyses of C ap ri foliaceae yield the fo l l ow i n g : ( C ap ri folieae (Diervilleae (Linnaeeae (Morinaceae (Dipsacaceae (Triplostegia,Valerianaceae)))))). On the basis of these results we provide phylogenetic definitions for the names of several major clades. Within Adoxaceae, Adoxina refers to the clade including Sinadoxa, Tetradoxa, and Adoxa.This lineage is marked by herbaceous habit, reduction in the number of perianth parts,nectaries of mul- ticellular hairs on the perianth,and bifid stamens. The clade including Morinaceae,Valerianaceae, Triplostegia, and Dipsacaceae is here named Valerina. Probable synapomorphies include herbaceousness,presence of an epi- calyx (lost or modified in Valerianaceae), reduced endosperm,and distinctive chemistry, including production of monoterpenoids. The clade containing Valerina plus Linnaeeae we name Linnina. This lineage is distinguished by reduction to four (or fewer) stamens, by abortion of two of the three carpels,and possibly by supernumerary inflorescences bracts. Keywords: Adoxaceae, Caprifoliaceae, Dipsacales, ITS, morphological characters, phylogeny, phylogenetic taxonomy, phylogenetic nomenclature, rbcL, Sinadoxa, Tetradoxa.
