Notes on Meaning

The common name "blue pimpernel" can be misleading, as the flowers of Collinsonia canadensis are typically yellow, not blue. The "blue" may refer to a slight bluish tint on the foliage or stem in some conditions, or it may be a historical misnomer. It is critically important to distinguish this plant from the more widely known "scarlet pimpernel" (Anagallis arvensis), which is a different species with red or blue flowers and unrelated properties.
