Becky-- you are correct. Cloning daylilies has not proven to be productive, and daylilies multiply much faster than hostas.
There is also the attitude difference toward tissue culture plants: Daylily growers are not interested in a mutation as a result of cloning. Hosta growers are thrilled to see a mutation and watch it continue to mutate until it becomes stable. Sometimes the results are spectacular.
Of course, hostas mutate in the garden all the time. The majority of variegated hostas are mutations, not seedlings. It is very difficult to produce a variegated seedling.
