The Latin name of seep monkeyflower was Mimulus guttatus and it belonged to the family Scrophulariaceae. That family has been radically altered and a great number of genera have been moved to the family Phrymaceae and monkeyflowers to the genus, Erythranthe . I grew it from seed some years ago and it promptly died after being planted out. It is naturalized in a few locations in Iceland, including along the stream that runs through my hometown. Those plants are well adapted and hardy in our climate. I transplanted a small cutting from there in my garden which is growing very well. It needs moist - wet soil and can grow in sun or partial shade.
