What is the difference between diploid and tetraploid daylilies?
Plants all have a basic complement of chromosomes. Most plants are diploidthey have two identical sets of chromosomes in each cell. Polyploids are plants with more than two sets of chromosomes. A tetraploid is only one of a whole series of polyploids. Triploids have three sets of chromosomes, tetraploids have four sets of chromosomes, et cetera. Tetraploid Tetraploid daylilies are heralded by some growers as having a number of advantages over diploids.
