I bought this gardenia at a botanical garden plant sale in 2006 and grew it in a pot where it was very happy and healthy. Several years later, when it outgrew the pot, I planted it in the garden where it went downhill immediately. I moved it to another planting area and it did no better. I dug it up and put it back in a pot, almost bare-rooted at this point. I didn't think it would survive. It not only came back with vigourous growth, but it was ready to be potted up to a larger vessel within a few months and had a healthy root ball again.
