It produces attractive flowers and fall foliage, as well as fruits that are popular with some species of bird. ==Description== Leathery deciduous leaves are simple and grow in opposite blades ranging from 0.5-3 inches in length and 1-1.5 inches in width.〔〔 Petioles are "rusty hairy" with grooves and sometimes wings.〔 Leaf margins are serrate.〔 Autumn leaf colors are bronze to red.〔 Twigs range in color from "reddish brown to gray"; young twigs are hairy, and get smoother with age.〔 Bark is similar that of the Flowering Dogwood, ranging in color from "reddish brown to almost black" and forming "blocky plates on larger trunks".〔 ''V. rufidulum'' blooms in April to May with creamy white flowers that are bisexual, or perfect and similar to those of other ''Viburnum'' species, but with clusters as large as six inches wide.〔 The fruits are purple or dark blue, glaucous, globose or ellipsoid drupes that mature in mid to late summer.〔〔 The fruit has been said to taste like raisins and attract birds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Viburnum rufidulum」の詳細全文を読む スポンサード リンク
