I have retrieved some Stella dOro daylily seeds from my sons very successful plants. Now what do I do to propagate them?
Since daylilies cross so readily (as do many other perennials), there is no guarantee seeds you collect and sow will be anything similar to the mother plant, in most cases probably not. This can be good if you want to see what you come up with, as breeders do in a controlled fashion. If you want to assure the same plant, you’ll need to propagate it such as by division. Sow seeds fresh, and even then they may take several months to germinate. Or you can hold in moist peat and keep around 40F for 6 weeks prior to sowing.
