Easy, easy, easy to grow!
Everybody loves Daylilies because there's really no other perennial that adds more color with less work. They stay low, they grow almost anywhere with sun or some shade, they always bloom, and their fountain of foliage shades out any weeds close by. The only work involved may be dividing them every five years or so when the clumps become so leafy it inhibits the bloom. But many gardeners don't even do that. Of course, they respond to regular watering, careful preparation of great soil, careful division as needed, and proper doses of fertilizer. So if you're a meticulous gardener, you can make them shine like no other group. But if you ignore them, they'll bloom well for you, too.
