I have grown lilies for several years and some have died out after many years (maybe 5 or 6). However, in the fall of 2007 I bought 3 each of Monte Negro (Asiatic), Lovely Girl (Oriental), and Casa Blanca (Oriental). These were bought mail-order from a reputable Canadian company, and planted near to a stand of trumpets which have been doing well over 5 years. The first year the survivors were: one plant of Monte Negro, 1 plant of Lovely Girl, and 2 plants of Casa Blance. Last year there were 2 plants of each (surprise!). This year, the only plants which survived were 1 Monte Negro and one Casa Blanca. This is only three years and I need to replace these plants. Is this normal for these varieties or was I perhaps sent sub-standard bulbs? I can't remember but I am sure I would have checked to make sure they were hard and looked good. It's not a matter of drainage because they are on a level area next to Hollyhocks which hate wet feet, and the area on the other side slopes down to another level area which collects all the runoff in the spring. Has anyone had this kind of experience with these particulr varieties? Any help would be greatly appreciated. Thank you.
