I wish I could grow some of the beautiful lichens I saw painting the rocks bright red in Namaqualand, South Africa. I have just discovered lichens have their own website: http://www.lichen.com/ as they certainly deserve. Diane Whitehead Victoria British Columbia, Canada where our lichens are gray, our rocks are gray, our sand is gray, our skies are gray, so you can see why colourful lichens are so exciting for me.
