Answer
Hello, Shaun;

I'm not quite sure what you mean by "sterile flower" plants...I know that plants like Hydrangea, Bird-of-paradise, & Roses (as well as other plants) are "sterile" in that there are usually no pollinators that help them propagate, in most gardens that they are planted in.

Article that discusses sterile plants and parts: http://www.1911encyclopedia.org/Flower

So, do you mean bulbs?  reply to clarify, please.  Thank.  ~Marc
