Roof Garden Plant: Daylilies


We planted a pot of daylilies in our Brooklyn roof garden at the recommendation of the helpful team over at Liberty Sunset Garden Center. In the spring and early summer, the lilies gave us a big punch of green. And the daylily started flowering during the first week in July, just as our Ameria maritima and a few other perennials stopped flowering.It was great to have the daylily bursting into flower for our 4th of July party.

Each flower doesn’t last long (hence the “day” part of the name!), but the plant keeps pushing out more flowers.

The daylily is presenting a few problems too. When it rains, the dead flowers from the daylilly fall off and get stuck to the roof surface. The flowers aren’t as attractive as we were hoping. Did all the June rain do something to the flowers? Or should we experiment with putting it in an even sunnier spot next summer? Or is it just that this particular variety (we can’t find the tag from this plant so we don’t know the exact name of it) doesn’t produce especially beautiful flowers?

By the way, daylilies are also grown in the roof garden on Chicago’s City Hall. And here’s the daylily collection at White Flower Farm. We’re wondering if other rooftop and container gardeners have any daylily advice for us.
