I picked up a palette or so of 1-gallon pots of variegated pittosporum as a special opportunity along with other excess plants that were being sold off last summer. They are around 14-18" high now. Landscape shrubs are not my specialty, but I have private customers (for whom I will be doing some landscaping on the side) who have inquired about them, and I don't know what to charge. Can anyone give some guidance?
