This is the first day lily of the year in our yard. To me, this marks the transition from spring to summer and although it’s been cool and pleasant (and rainy) the last few days, the forecast is for hot and humid tomorrow and through the weekend.
While spring flowers are relatively fleeting (except the daffodils, I suppose, which last a while, summer flowers are more enduring. Not the individual flowers, which are generally here one day and gone the next. But using day lilies as an example, they tend to bloom continually, with new flowers each day, for weeks or in some cases all summer.
