Scarlet Butterfly Weed / Gaura coccinea

This macro shows a single flower from a spike of several small flowers belonging to a Scarlet Butterfly Weed plant. There are four spoon-shaped petals which are white to yellowish and these may turn pink with age, sometimes a very deep pink/scarlet. Photographed yesterday afternoon at Erlton/Roxborough Natural Area, on my way home after a volunteer shift. This is perhaps the richest area in the city for wildflower species. Unfortunately, it is being seriously overtaken by invasive weeds, like Goat's-beard. Another weed doing a lot of damage there is Baby's-breath, which probably started when someone tossed an old vaseful of flowers over the fence from the cemetery that backs on to the natural area.

Apologies for replacing this image later - seemed strange that there was only one comment in 7 hours (same as with another photo posted this morning). I wondered if maybe my photos weren't showing up?
