A good year for flowers, and even a bit on the late side. Maybe all the rain earlier. Average for flowers I would say is about 6/15, but it is certainly a bit variable.
I'd think it varies with latitude, as these things tend to do. I didn't notice laurel flowers at Ratlum, but maybe I was too busy looking at my map. Were they gone by?
Mostly gone by. Just a few hanging on. They were pretty much still in full force when I got home on 6/23, but maybe peak would have been a few days earlier. Some years they have cleared out around the first week in June. But sure, latitude and altitude are factors, too.
