Foxglove Beardtongue

Here's some Foxglove Beardtongue from last spring. This is a native wildflower with (somewhat) bell-shaped blossoms that's considered popular with all bees but especially favored by bumblebees. What a name, heh? It almost sounds like the name came from a random name generator that went on too long. It's actually named after 2 different genera of flowers, the foxgloves and the beardtongues . Since Foxglove Beardtongue is a type of beardtongue but is not a type of foxglove, you should probably interpret the name something like "a beardtongue that resembles a foxglove". (Since both foxgloves and beardtongues are in the plantain family , perhaps it's not too surprising that there's a resemblance between the 2 [1].) What are the differences? This article (which seems to mix up species/genus a little) mentions several things, like foxgloves being from Europe and having bell-flowers that hang down while beardtongues are North American plants with tubular flow...
