Chelle: More to know about virus, also. I was a little abreviated yesterday. A virus runs all thru the plant in its 'bloodstream' so to speak. And plants--just like people--catch it from one another. A virus is spread by mechanical means; the most common is aphids being transported be ants from an infected host plant to a healthy one.
Another is bunnies and rodents nibbling on an infected plant either above or below ground and sampling back and forth with contaminated saliva. A third way may surprize you: the gardener will spread a virus quicker than quick while picking a bouquet with a contaminated scissors or while trimming flowerheads, etc. Viruses, unlike fungus and mold are rarely, if ever, airborne. And there are some types of virus with which a lily can live and function with satisfactorily too--like a person getting a cold, but add another and it gets more difficult for both lilies and people function and still look good, etc.
And some other regulars on this forum could add to the list of how virus can be spread, I'm sure.
