This is in addition to Propagators post # 30 on this thread relating to a nursery.
Someone suggested we visit a nursery on Khon Kaen’s University campus. They have a wide variety of plants available (many others things also,...some good looking sales women working there). There are also two restaurants and one coffee shop in this area.
I think, as we were told, this area has something to do with the universities agricultural department. There are a lot of small plants geared towards the dorms/apartments that you can purchase here. They also have some larger plants (maybe for the homes on the campus), but not as many. You might have to order them if you are looking for quantity.
There is also an annual fair held at the end of January that the universities agricultural department puts on, where you can purchase plants.
