This popular garden ornamental, a native of Southern Europe, exhibits UV-dark false-blue flowers similar to its cousin S. officinalis. Interestingly, the flowers fade to pale UV-light tones as they age. I do not know what has caused the white speckling seen in both the UV and the Visible frames, but it is probably caused by an aging or weathering factor as there did not appear to be any insect damage on the plant.
