I have purchased from him once. His plants were healthy, and he had good amounts of each for the price. I also got a discount on shipping for getting more plants. The only thing I noticed is that when I asked for dwarf sags, I got microswords, and they looked like they were grown out of the water. This means I should have cut the blades off before planting. He offers both so maybe it was an error on his part.
I recently ordered more plants from him, and I should receive them this week.
