Konrad Your Tiger lilies are beautiful. We have the lily beetles around, if you don't watch they will decimate the leaves. Looks awful. If you spot any beetles, even one, just squash it (yuck!) or drop into jar with some water in it. Anytime there is a black gunk on the underside of the leaves (that is actually excrement with larvae in it-yuck again!), knock it off with a spray from hose. Larvae will die if not on the leaves-no food. That's best way to control them. (See photo what happens if you leave them on...) Most important is to get rid of adults so they don't breed. Hope you never see them...Rina

As mentioned by Suenh, Tiger lilies are resistant to most lily virus, such as TBV and the cucumber Mosiac Virus. However, they can still host the virus inside them and this virus can be spread by gardening tools (cutting flowers on both lilies, one after the other) or by insects (primarily aphids). If you have an asiatic lily with virus it typically displays symptoms which allow you to cull it. However, with tiger lilies, you may not know that it has virus since it does not display any symptoms and the only hint may be lilies gradually getting infected and dying around it (or near it). That being said, I grow tiger lilies and have not had a problem. I am rather virgillant about aphid control and I dip tools in a bucket with 10% bleach solution (9 parts water to 1 part bleach) between each cut when I deadhead flowers. Just because you have not had problems, does not mean it can not become a problem in future, and having a "trojan horse" in a garden could eventually become a problem, especially if you are a lily collector. If you are a casual gardener, it is certainly worth the risk because with some regular sound care you can keep all lilies happily growing and if you have a really bad year, worst case replant some lilies (including the tiger lily). Personally, I hate to get rid of them because they are so pretty and it goes against everything I believe it when you get rid of the lily which is virus resistant to protect the lilies that are susceptible for virus infection.

'Ditch lilies' are not lilies at all but rather a variety of Hemerocallis or daylily. Lilium lancifolium will grow to a range of heights - anywhere from 2.5' to over 6' - depending on growing conditions and bulb maturity. btw, tiger lilies - Lilium lancifolium - are a primary vector for lily mosaic virus and are generally NOT recommended to be planted with other types of lilies. They are unaffected by the virus but most other lily species and hybrids are and will develop distorted foliage and stunted growth and eventually weaken the bulbs to the point where they will die.

With luck they should grow and flower as normal next year. ==>> well.. thats an understatement ... if these have been sitting in poor improper conditions.. say in a bigbox or hardware store.. odd are very high .. little or nothing will come of them ... but if only one or two do.. then you probably beat the bargain.. as those two at full price probably offset the loss of the rest .. if they do sprout green.. we need that green to feed the bulb for next year... proper storage of bulbs.. aka.. onions.. or root stock like potatoes.. etc .. was the old fashioned root cellar ... 50ish degrees.. dampish.. etc ... most of us now would call that an unheated basement ... bigbox is not a root cellar.. lol ... ken
