Could someone please give me a link to find out why a flower would change its color. By this, I don't mean that it fades. I have a very old mature adenium--had been 4 months since it last bloomed--the flowers usually open with a coral hue, then turns to pink. Today however, a blossom opened in red! Even my husband noticed this, so I know my eyes are okay.
Thank you,
