Wildflower

 

Synonyms:

  • Lythrum salicaria var. gracilior Turcz.
  • Lythrum salicaria var. tomentosum (P. Mill.) DC.

Comment:

It is really a pity that such a lovely flower is an invasive pest in the New England area. The purple flower spike is striking in both Visible and in Ultraviolet light. In UV the petals feature a pretty false blue center stripe against a pale, UV-reflective, false yellow. The center of the flower is UV-dark.
