What is "romneya"

n. (context botany English) Any of the genus (taxlink Romneya genus noshow=1) of flowering plants of the poppy family, perennial subshrubs with woody stems and large white flowers with yellow centres.

Romneya 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. 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. 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. It is also known as the "fried egg flower" or "fried egg plant".

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.
