I dunno If I would hold this aganst him. Most every LFS I've ever gone to does the same thing with mondo grass. Knowing this I would simply not order that particular plant.so far we caught him using a deceptive photo, and incorrectly identifying a plant;
(this plant is immersed mondo grass, or Ophiopogon japonica, and the color is green)
eBay: OPHIO PUSILLUS so only order widely known plants, and nothing too unusual.
I would give him a try, but I would keep my first order small, and my expectations low.
He ships free FIRST class mail, so only order once the weather is well above freezing.
