Daylilies

You're probably seeing daylilies showing up in gardens and elsewhere this week.   Asiatic daylilies are in genus Hemerocallis, and are considered to be an adaptable perrenial staple for many gardeners.  I've read that they're considered by some to be invasive, and I've seen little clumps in remote places occasionally. I like them for the same reason I like the mallows: they produce a new flower almost daily (although each flower lasts for only about 24 hours).
