I've pretty much figured out why though. All of the lilies bloomed on schedule, my begonias, which get full sun almost all day, have grown freakishly huge this year, the geraniums are blooming beautifully, but my impatients are pitiful. Those growing in the shade are doing OK, but those that get sun are struggling. I made the mistake of planting a dark magenta color in the flower box that lines our driveway, and the dark color is absorbing too much of the sun and half of them have decided to just shut down and barely hang in there. By this time of year, they should be two feet high and two feet wide. I suspect, if they were a lighter color, they would have deflected the heat a little better and grown normally. Guess I'll have to rethink color schemes next year if these increased temperatures continue. It's definitely the heat that is stressing some of my flowers this year.
I'm happy to report though, we have had lots of bees, butterflies, hummingbirds, and rain this year.
