I have a question about Tiger Lilies. I seem to remember that they are likely to carry a virus that is highly transferable to other Lily hybrids. Can others talk about whether they grow them in the same beds with their species or their hybrids. I also remember reading that milkweed plants, because they attract aphids, are vectors for the viruses. I don't want to be paranoid but just well informed, as I have both in my garden. Thanks.
