Quite a few of my various trichocereus sp. plants are showing a wonderful blue color. Is this a sign of health or stress. These are plants that have been that blue in earlier years.
very interesting question that has arrisen for me lately. Someone wanted a plant similar to one his friend bought off me, describing it as 'glaucous blue' (iirc). I told him that afaik I sold him one of the same species. Sure enough after giving his one some love and care it also developed the blue tinge. So, my answer would be: a sign of good health!
