Plants reach 20' to 30' in height, 15' to 25' in spread. Flowers perfect, white, fragrant, borne in large, terminal, 6" to 12" long, and 6" to 10" wide panicles, in early to mid-­‐June, effective to 2 weeks; extremely showy in flower. Bark cherry-­‐ like, reddish brown to brownish on young and old stems, marked withprominent horizontal lenticels, becoming gray and scaly on older trunks. Somewhat similar to S. reticulata, but smaller (15-­‐ 20') with a more informal (multi-­‐stemmed) habit, and finer texture throughout. The leaves and stems are smaller and finer. The flowers are creamy white and appear before those of S. reticulata in 3-­‐6" long panicles. Habit bushy, spreading and rounded. Bark often quite handsome, being sometimes similar to that of S. reticulata, or on some trees, may exfoliate in rich brown flakes or sheets. Plants have a densely rounded, compact habit and reach 20'-­‐25' in height. Leaves are very dark green; flowers are abundant and produced at a young age. LILAC An extremely hardy species related to S. villosa. A medium-­‐sized to large shrub with pale, ash-­‐gray branches and elliptic-­‐lanceolate, taper-­‐pointed, 8-­‐ 12 cm long leaves. Flowers fragrant, pale violet-­‐ purple, borne in wide, loose panicles in June. SIEBOLD VIBURNUM Large shrub or small tree of open habit, Foliage lustrous dark green, with fetid odor when crushed; fall color usually green, occasionally red-­‐ purple; Flowers creamy-­‐white, borne in late May in 3" to 6" diameter Fruit a 1/3" long rose-­‐red drupe, changing to black, effective for two weeks in August through early October; although inforescences are a handsome rose-­‐red, and remain effective for 2 to 4 weeks after the fruits are gone. 7 scientific name Viburnum sieboldii 'Seneca' common name notes SIEBOLD VIBURNUM Selected for its abundant, large, firm red fruit on red pedicels stay on the plant up to 3 months before turning black at maturity and falling, and massive creamy-­‐white panicles produced in May to early June as the young foliage unfolds. Although 'Seneca' is tree-­‐like, and has attained a height of 14' and a width of 13.5', the plant can be trained with several branches from the base and kept as a large spreading shrub. The cultivar will undoubtedly equal the species in size and be as tall as 30' with a gnarled trunk. 8
