<<Those exotic iris are tall bearded iris,
Since Keith is new to the world of irises, I think it's only fair to
point out that the color of an iris, exotic or not, is subjective at
best. And, as often discussed on this forum, in real life and real time,
color is effected by many things, including soil components and
temperature. Higher temperature will water down or lighten the
darkest of colors.
People often think they have received the wrong iris, simply because the
color is not as deep or saturated as a picture they have seen would
indicate. Judges argue this point at shows.
Hydrangeas are not the only flowers effected by the ph of soil.
