Listed below are people credited for the origination and/or registration of multiple new cultivars of hosta. The top list are those who are associated with hybrid cultivars. Some of these new plants are the result of breeding done by the hands of the hybridizer while others were accomplished by bees.

The lower list are those who have originated or registered hosta sports. These new plants were either "discovered" in the garden or nursery or came about as the result of the tissue culture propagation process.
