My first thought was that the plants on the left side of the picture, up against the fence, were daylilies too. We have bird of paradise here in southern California, and the broad base of the foliage looks more like the bird of paradise foliage. But, unless there's a different species of bird of paradise in Florida, they usually don't bloom until they're a bigger plant. I enlarged the picture to try to get a better look at what appears to be leaves against the house and behind the water faucet, and I'm not sure those are leaves. Individually, their shape is more rectangle than the oval shape of a leaf. I think it might be part of the mulch - cedar bark. It looks like what new cedar bark would look like, while the other bark, exposed to the elements, is aged. Something could have been sitting on top of some of the cedar bark, cause it to age differently as it was protected from sun and rain.
