Nasturtium 1. An almost meditative look at the intense green of a nasturtium leaf. So few botanicals radiate like the Nasturtium, both in its color and in the pattern of veins. This is another photograph that highlights my fascination with branching structures and networks. The scale of this photo is approximately 1/2 inch across and is enlarged almost 30 times life-size in a 12 by 15 print.
