There are lots of quality perennial sellers on the internet. There are also lots of inferior quality sellers on the internet. After years of planting numerous types of catalog perennials only to have them die by the next season, I discovered the beautiful and hardy daylilies, hosta and iris.
I continued my search for these hardy perennials, eventually turning to the internet. The next step was discovering what sellers I could trust, and those that I could not. The daylily community is close-knit, so fortunately there are few truly unscrupulous sellers. Some would not stand behind their products when they faltered, some sent smaller than expected fans, some were not reliable on their shipping, and some charged exorbitant prices for their plants.
