As far as I know, she doesn't charge extra at all. She charged me $17.50 for this rose, and it was a 3-gallon rose by the time she sent it. That's the price some places would charge for an own-root band that isn't custom-ordered or custom-grafted.
When she sent me her list of available plants, there were other budded varieties on it, but I can't remember what they were now.
She really is an amazing resource, and all of the plants I received from her are doing well. Mortality rate of 0%.
