What's all this about diploid and tetraploid?
Daylily aficionados often use the terms “diploid” or “tetraploid” to describe the different kinds of plant. Diploid refers to a plant with two separate sets of chromosomes. Diploids have 11 chromosomes from the egg cell and 11 from the sperm cells of its pollen which means that one set is inherited from each parent. Tetraploids have four sets or 44 chromosomes. You probably don’t give a hoot about this except to note that tetraploids often have larger blooms and diploids often display the prettiest pinks.
