The Conejo Valley Botanic Garden in Thousand Oaks is home to thousands of Matilija Poppies and they are blooming like crazy right now!
The Matilija Poppy bears the largest flowers of any California Native plant, up to 9" in diameter. They bloom in late spring to early summer.
The Chumash enjoyed this plant that was named after Chief Matilija and his tribe in the early 1800s. Matilija is pronounced ma-til-a-hah (not jah).
The genus of this plant is "Romneya," named after Irish astronomer John Thomas Romney Robinson. Romneya produce the largest flowers of any members of the poppy family.
