Typical division: two of the same JI.

Tets are double the chromosomes of Diploids. Since I've collected daylilies and JI's for years I really feel the difference is seen more with Tet daylilies having stronger stems and more substance though some of my favorites are diploids. With JI's I know the Tets are supposed to be more desirable but none are even weak stemmed whereas many of the diploid daylilies can be blown over by wind. Colors are supposed to be more vivid as well but I truthfully don't see the difference with color for either plant.
