A good watering should be given immediately after planting and the ground should be kept moist for the next week. This not only makes your garden look better, but also prevents unwanted seed pods from forming that can rob some energy from the plants. In species daylilies that reproduce by seed there are 22 chromosomes. The superiority of induced polyploid plants over their 22 chromosome diploid ancestors led to experiments to induce tetraploid daylilies with 44 chromosomes. Color of flowers are more intense.
Scapes are sturdier and stronger.
Substance both in flowers and leaves is often heavier. Vegetative vigor in leaves, stems, and flowers is thought to be greater. There are also an increased number of breeding possibilities with the greater number of chromosomes. Meanwhile the diploid varieties continue to charm many with the exquisite flower form, grace, and color. Good pink daylilies are still more prevalent in diploids.
