This "white" daylily is my personal favorite. Every bloom looked just this good and it had lots of them over the course of the summer.
This red bloom was gorgeous in the morning when it first came out. The sun would bleach it quite a bit as the day wore on. These dark colored daylilies should be planted in partial shade.
Have a look at this wine/purple flower. Do colors get deeper than this? This is another that needs protection from the sun to keep its colors looking best.
Daylilies are easy for anyone to grow. They grow about anywhere in the US. I highly recommend them. Were I to do it over again, I wouldn't plant a whole bed of them because they look weedy when they aren't blooming. I think it's best to have clumps of them scattered in amongst other plants.
