Brandenburg, ''Field Guide to Wildflowers of North America'', National Wildlife Federation, Sterling Publishing, New York, 2010. (pp. 432)〕 is a North American species of ''smartweeds'' within the buckwheat family. It is unusual as a shade-tolerant member of a mostly sun-loving genus. Jumpseed is a perennial, named for its seeds which can "jump" several feet when a ripe seedpod is disturbed. ''Persicaria virginiana'' blooms in midsummer to late summer/early fall. It has a stalk of small white flowers.〔(''Persicaria virginiana'' (Linnaeus) Gaertner ), Flora of North America〕 ==Identification== Like other ''Persicaria'', jumpseed has alternate leaves, with fine-hairy stipular sheaths with bristle-fringed edges which often turn brownish. Flowers, widely spaced along slender stalks, are white to greenish-white, rarely pink-tinged, and fruiting flowers have 2 downward-pointing hook-tipped styles.〔 ''Persicaria virginiana'' is easily distinguished from most other ''Persicaria'' by its much larger, more oval-shaped leaves, although a few species also have large leaves. It sometimes has a chevron-shaped marking on the leaves; often a single plant will have this marking on some leaves but not others. Cultivars and naturalized populations from cultivation show much greater variation than wild-type plants, sometimes having variagation or have more involved red patterning, and sometimes having red or pink flowers. 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「Persicaria virginiana」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
