Description
''E. lutea'' blooms in the summer and grows to about in height. The flowers are yellow with irregular red blotches and the leaves are hairy, paired, and round. Because of its yellow petals, ''E. luteus'' is in the "yellow monkeyflower" group, unlike most members of the genus, which have red or pink petals. Some sources list ''Erythranthe lutea'' separately due to chromosomal variations. Barker, etal (2012) proposes a new taxonomy for Phrymaceae, leaving only 7 species in ''Mimulus'', none in ''Mimulus lutea'', and placing 111 in ''Erythranthe''. Barker also offers 4 different options for how to implement this new taxonomy. The ''luteus'' group consists of ''Erythranthe luteus'' var. ''variegatus'', ''E. naiandinus'' and ''E. cupreus''.Distribution and habitat
''Erythranthe lutea'' prefers to grow in wet habitats such as marshes and riverbanks. It is native to temperate South America, including Chile and western and southern Argentina. It has been naturalized in Britain, having been first cultivated there circa 1826.References
