How can I propogate Coreopsis flower?
I bought Coreopsis "Illico" variety in Lowes and I really like the flower but I can not find it in Lowes anymore. Not only that I can not find any references to this type of flower on any US websites, there are some references on UK and for CZ (Czech I assume) websites. So I'm left only with option to try to get seeds out of current flower and try to grow it. What do I need to do to make it happen? I have dried out whatever left of flowers and i put it container, covered it with soil and watering it daily. It has been 5 days now and I can not see anything coming out of it. What am I doing wrong?
