What is surprising about this shot is that while the flowerheads themselves show the typical IR response of foliage - their yellow colour turning to bright white, the sepals of the flowers appear to absorb IR radiation and are seen as more or less black. Almost all other plants have sepals that show the more typical IR response of white.

Recently, I had the opportunity to investigate this anomalous IR photographic response once again. The first point to note is that I was incorrect in calling these plants Hawksbeard. In fact, they are probably one of several hundred (!) varieties of Hawkweed - a member of the
