(Foxglove [Digitalis purpurea] is a common weed of the North Pacific slope. While non-native, and virulently poisonous if eaten, it's generally escaped the "invasive" label. I'm not entirely sure why, but it probably has much to do with the fact that it has a pronounced tendency to colonise poor, erosion-prone soil snubbed by other plants. This landslide site in the bluffs above the beach is a good example.
That, and its singular beauty, may have earned Digitalis a measure of tacit support here.)
