German to English Science Botany Botany

This query is not actually directly related to a job I'm doing - I think it's the first time I've made a non-job-related query here. That's why I'm asking it in the Easy section. But also, I suspect the solution is fairly straightforward.

Very simply, I need to know what a "Mehlprimel" is called in English. Would it be "white primrose"? TIA for your confirmation or correction.
