Abstract: In cultivation Hemerocallis can be self and cross fertilized. Through a long period of
cultivation and observation of the resulted hybrid seedlings，which showed a great variability in
ornamental characters，10 individuals with high ornamental value and good adaptability were selected.
They have been multiplied by in vitro rapid propagation and division propagation to establish 10 clones as
new cultivar，which are different from each other in flower’s colour and shape and are suitable for most of
the regions in China.
