Two opened today which show just the slightest (look close) hint of color on a couple of petals edges; the remainder that have opened remain completely white. I have hope that this is just a weather/temperature situation and not something more insidious. It also occurred to me today that most of our lilies are planted against a heat radiating brick wall. I have to wonder, based Roosterlorn's suggestion regarding temperature, if where they are planted could be a contributing factor? Essentially, I'm wondering if I might have created a micro-climate which might be working against me?
