one of the earliest spring flowers, has virtually no
visual indication of a bull's-eye pattern. UV reflectance
of the outer petals is quite high, but somewhat varying.
Thus, the flower heads may record with the outer parts
being pinkish instead of white. The central flower disc
has no UV reflectance and thus records almost black in
b/w UV, and in bright red for UV colour.
Tussilago is eagerly visited by smaller flies and honey bees. Being one of the first flowers to appear in the spring, it evidently can advertise its presence with great success to the few insect pollinators available. Come to think of it, these pollinators have but few food sources this time of the year, so the interest of having the flowers easily located is mutual to pollinator and plant.
