Thanks for asking this question! I have been threatening my Auroras for several years now with expulsion from my ponds for being the stingiest blooming lilies I've ever had. I've told myself I should toss them on the compost pile- it's just hard to make myself do it! No more excuses. Out they go! There are plenty of other fantastic blooming lilies needing the space. My most prolific bloomers are Texas Dawn, Pink Grapefruit, Colorado, Peach Glow and Clyde Ikins. I am in southwest Iowa and my 3 ponds of lilies suddenly exploded with growth this last week. I was starting to question my water gardening skills this year, but now I think it just hadn't been hot enough for a long period of time. Anyone else in my region have the same experience this year?
