Carole, please don't let my fear stops you from growing daylilies. You will find that daylilies are the most wonderful plants whose diverse blooms will give you so much joy. Let me just put something in perspective here. Even with rust and pests, you can still grow at least 40 of these plants in your garden without too much fuss. My problem is that my number has now increased 10fold so that a significant part of my garden is devoted to daylilies. Imagine seeing rusty plants everywhere you turn to. Though I am sure my situation is not as bad as those in the south parts of the US where daylilies grow year round.
