Agalinis (false foxglove) is a genus of about 70 species in North, Central, and South America that until recently was aligned with members of the family Scrophulariaceae. [2] As a result of numerous molecular phylogenetic studies based on various chloroplast DNA ( cpDNA ) loci, it was shown to be more closely related to members of the ...

Shade-intolerant species require full sunlight and little or no competition. Intermediate shade ...
