Moving many mature plants from one garden to another three and one-half 
years ago seems to have altered the flower color in some. Soil in the 
first garden is very well drained. rocky,  volcanic "shot clay" with 
high iron and potassium levels. That in the new garden is fairly heavy 
clay (also of volcanic origin but at lower elevation), now well amended 
with organic matter, with none of the red color seen in the former. Two 
species of Paeonia, both grown from wild-collected seed in the 
mid-1990s, are particularly different. Paeonia mlokosewitschii was cream 
with a pink flush, mostly from pink veins; now it is clear pale yellow. 
Paeonia officinalis was a beautiful blood-red; now I would call it 
rose-red, a less striking color.
Have you noticed other geophytes that vary in flower color in different
