''Romneya'' 〔''Sunset Western Garden Book,'' 1995:606–607〕 is a genus of flowering plants belonging to the poppy family (Papaveraceae). There are two species in genus ''Romneya'', which was named for Irish astronomer John Thomas Romney Robinson.〔(Jepson Manual Treatment )〕 They are known commonly as Matilija poppies ( ) or tree poppies and are native to southern California and northern Mexico. They are perennial subshrubs with woody stems. They may grow to a height of and a width of , with the flowers up to across. The silvery green leaves are deeply cut, with a small fringe of hairs at the margins. They are notable for their large white flowers with intense yellow centers, blooming in summer. ''Romneya'' produce the largest flowers of any members of the poppy family.〔(Flora of North America )〕 These flowers prefer a warm, sunny spot and fertile soil with good water drainage. They are not easily grown but once established are difficult to remove. In the wild, they are known as "fire followers" as they can be frequently, but not exclusively, found in burned areas.〔Quinn, Ronald D. and Keeley, Sterling, C. (2006). ''Introduction to California Chaparral''. Berkeley: University of California Press. p. 145.〕 It is also known as the "fried egg flower" or "fried egg plant".〔Gutierrez, Mary (2013), (Matilija Poppy ). In Northwest Garden News, online edition. accessed 5 July 2013.〕 The two species are: * ''Romneya coulteri'' Harv. - Coulter's Matilija poppy * ''Romneya trichocalyx'' Eastw. - Bristly Matilija poppy. Some consider this a variety of ''Romneya coulteri'', but it is accepted in recent manuals. == References == 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「Romneya」の詳細全文を読む スポンサード リンク
