You could be excused for wondering whatever is happening with this daylily bloom. While daylilies normally have three outer sepals and three inner petals, the Quality of Mercy bloom shown above has five of each! This makes for a very full, round flower. Such blossoms are termed polymerous. Formerly, the term ‘polytepal’ was used but ‘polymerous’ reflects more botanically-correct terminology.
