Re: CULT: reversions (LOWI)


>So the question is, since we know that soil conditions can affect color 
of the same cv from place to place, could soil, bereft of those 
micronutrients used by irises. 
This is something that has occurred to me, but with my lack of iris 
growing experience, I was loath to suggest. The colour change that most 
gardeners would be familiar with is that of Hydrangeas. Mine went from a 
lovely burgundy pink, to irridescent bright blue when we shifted here. 
Black cattle will change coat colour to red, if certain 
vitamins/minerals are not present in their diet. Don't quote me but I 
vaguely recall Selenium/Vitamin E being the offender here. 
I really think that this thread is worth persisting with, and that some 
botanical, or horticultural reading would be in order for those 
interested in getting to the bottom of the mystery.
