But how many of you have problems with Xylella?? My guess is none.. 
It's not that it would impact European Hemerocallis but that infected (and not necessarily symptomatic) host plants pose a serious risk to agriculture, e.g. olives, citrus, grapes, almond, peach, plum and also ornamentals like oak, sycamore and oleander because insects feeding on an infected plant can then transmit the bacterium to other plants. According to the article:
http://www.efsa.europa.eu/en/f...
"The two main pathways for entry of X. fastidiosa into a previously unaffected area are through trade of infected plants for planting, and the presence of infectious insects in plant consignments."
There's an article in a British newspaper about what Xylella is doing to the olive groves in Italy:

From a purely daylily perspective, we now have, for example, daylily rust, daylily leafminer and daylily gall midge in North America that have somehow slipped past phytosanitary requirements from other country/ies in the last fifteen years.
