    'Ivory Silk' Japanese Tree Lilac

    Fact Sheet ST-611 October 1994 Syringa reticulata ‘Ivory Silk’ ‘Ivory Silk’ Japanese Tree Lilac1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION Although a Lilac, this member of the species is quite different in appearance than those with which gardeners are more familiar (Fig. 1). Its upright habit varies from symmetrical to irregular but is more consistent than the species. Cultivars including ‘Ivory Silk’ and ‘Summer Snow’ could be used instead of the species due to the more consistent habit and more flowers. ‘Ivory Silk’ grows well only in USDA hardiness zones 3 through six (perhaps into 7) and has an oval or pyramidal form when young but spreads to a rounded shape as it grows older. This is a very large shrub or small tree, reaching a height of about 20 to 30 feet with a 15-foot-spread. The huge clusters of creamy white flowers, borne in early summer for about two weeks, are the main ornamental feature but lack the fragrance of the spring-blooming Lilacs -- this Lilac’s fragrance is more suggestive of Privet.

    J. AMER.SOC.HORT.SCI. 142(4):279–288. 2017. doi: 10.21273/JASHS04155-17 Intraspecific, Interspecific, and Interseries Cross-compatibility in Lilac Jason D. Lattier 1 and Ryan N. Contreras 2 Department of Horticulture, 4017 Agriculture and Life Sciences Building, Oregon State University, Corvallis, OR 97331-7304 ADDITIONAL INDEX WORDS. Syringa, Pubescentes, Villosae, in vitro germination, controlled crosses, wide hybridization ABSTRACT. Lilacs (Syringa sp.) are a group of ornamental trees and shrubs in the Oleaceae composed of 22–30 species from two centers of diversity: the highlands of East Asia and the Balkan-Carpathian region of Europe. There are six series within the genus Syringa: Pubescentes, Villosae, Ligustrae, Ligustrina, Pinnatifoliae, and Syringa. Intraspecific and interspecific hybridization are proven methods for cultivar development. However, reports of interseries hybridization are rare and limited to crosses among taxa in series Syringa and Pinnatifoliae. Although hundreds of lilac cultivars have been introduced, fertility and cross-compatibility have yet to be formally investigated. Over 3 years, a cross-compatibility study was performed using cultivars and species of shrub-form lilacs in series Syringa, Pubescentes, and Villosae. A total of 114 combinations were performed at an average of 243 ± 27 flowers pollinated per combination. For each combination, we recorded the number of inflorescences and flowers pollinated as well as number of capsules, seed, seedlings germinated, and albino seedlings. Fruit and seed were produced from interseries crosses, but no seedlings were recovered. A total of 2177 viable seedlings were recovered from interspecific and intraspecific combinations in series Syringa, Pubescentes, and Villosae. Albino progeny were produced only from crosses with Syringa pubescens ssp.

    Disease and Insect Resistant Ornamental Plants: Syringa

    nysipm.cornell.edu 2018 hdl.handle.net/1813/56377 Disease and Insect Resistant Ornamental Plants Mary Thurn, Elizabeth Lamb, and Brian Eshenaur New York State Integrated Pest Management Program, Cornell University SYRINGA Lilac pixabay.com Syringa is a genus of about 30 species of lilac trees and shrubs native to Europe and Asia and widely grown as an ornamental in North America. For many, “lilac” brings to mind the common lilac, Syringa vulgaris, known for its fragrant masses of purple, lavender and white blooms in May. However, the common lilac is susceptible to several diseases and insects, including powdery mildew, bacterial blight, scale and borers. Some disease-resistant cultivars have been reported, and there are other less susceptible species and hybrids available. DISEASES Powdery Mildew is a common disease of lilacs caused primarily by the fungus Erysiphe syringae. Leaves of infected plants develop a whitish coating during the summer, and while it does not usually cause permanent damage, aesthetic quality can be greatly diminished. Cultivars of S. vulgaris are more susceptible than those of most other lilacs (8), and plants in shady sites with poor air circulation are more likely to be severely affected.
