I am in your same zone. I have one & it begins blooming what I consider late. Let me think now as best I can as to exactly when it begins it's bloom period. I'm going to say July. They do not begin blooming in spring. However, they continue blooming later than many other things. Mine is still blooming & will continue at least through September. I imagine yours will run along more or less the same time periods. I like them a lot because the butterflies & hummingbirds can feed at them and I don't have a whole lot of other things blooming at this time of year. All the daylilys have finished blooming, bulbs are done blooming. They do handle the searing heat as well as drought VERY well which is a major plus in my book. They will also root along the stems if you have some nice mulch around them & bury a stem in the mulch. Next spring, you will find roots on that stem & can cut it off from the parent plant & plant it somewhere else. Or you can just let it "crawl" & take over a larger space.
