The strong spring winds go on and on, so I put into use a Kaiser light tent purchased several months ago. Useful, but did not totally eliminate flower movement. This flower is a 25x stack. I'm not very happy with the composition so have made no effort to touch up the glaring artefacts resulting from subject movement and change of focus. But I can't find out what it is, for when I make another attempt. The reliable New Zealand Book of Weeds does not appear to have it. It is a shrub about 75cm tall with 2cm 4-petal purple flowers. Large leaves, pale green with lighter borders. Most weeds are not native so it probably originated overseas. Any ideas?
