This is my version of developing hostas. It was inspired by Mary Ann. If someone wants to add to it or correct me on anything please go for it. This is just the beginning, will improve it as time goes on.
If you happen to grow hosta seed from streaked plants or are lucky enough to have a plant sport(division arising from the result of mutation, chimeral rearrangement, or mitotic recombination) or just need to keep an unstable plant unstable then you are going to have to dig them up and separate the divisions. This might seem pretty obvious to many people but some might need a little encouragement.
The first three plants are examples of this. You can separate the mediovariegated divisions(center lighter than the edges) from the plant and let them develop or stabalize separately. It just happened that all three are mediovariegated, more often they are edge variegated.
This plant below is the best example of a plant with many leaf types, (1)a green division, (2)a streaked division or divisions, and (3)a medio-variegated division. When you divide it you still would have a streaked division for possible breeding and keeping unstable and let number 3 stabilize more into a new plant. In this case the green division wouldn't be worth much but in some you never know.
These are limp from dividing them. They were taken inside with flash so they look a little like a different plant.
Below are 9 divisions from a plant I divided last fall. It gets much golder and brighter either later in the season or with more sun, don't know which caused the brighter colors. I had a spot on the north side of the house and put them there, might not have been the best place for this particular plant. As the summer goes on I will replace these with later and hopefully better photos.
Probably will go all green eventually
The next 3 divisions I hope develop an lighter colered edge to them.
This one has the best prospects so far as an edge variegated plant, will grow it for awhile and then divide off the best part and let it grow for longer.
A solid colored division and a couple of streaked ones below that.
I divided a division from the first plant below which eventually became the second.
Other things you can do and I am sure no expert on them is bud cutting, rossizing, and even using bap 10 on them. Supposedly if you have just one nice leaf on a plant and you want to create a new plant you can cut the bud out in the fall with some of the stem and roots and pot it up and in the spring the bud will grow and be the same as the leaf. Rossizing is inserting a sharp knife into a stem above the dormant buds and cutting down which isolates each bud so the plant sends out new divisions from the dormat buds, having the same leaf as the already exposed leaf,and then replant it. Another thing that can be tried is bap 10, a hormone that breaks the bud dormacy.
This is just to inform you of them, not to encourage you to try any.
