Purple laurapetulum (right) and Flowering Cherry leaves Left on cotton. The laurapetulum continues to give quite good prints in pink shades but the flowering cherry is quite a pale yellow. Soon the prints will get a golden colour as the Autumn comes on. I wonder if the changes in tannin are more pronounced in deciduous trees than those (like the laurepetulum) that are evergreen. I am finding I use more deciduous trees for eco printing with the exception of eucalyptus.
