Daylilies or Hemerocallis come in so many heights, colors, and flower forms that only a public garden could have a significant number of them in a collection.
Even though yellow is not a flower color I aspire to have more of in our garden, this Kindly Light Daylily is one that is so lovely, it is hard to resist.
Old House Gardens catalog describes it as "decidedly different" and the first spider Daylily.
The roots are $7.50 each at http://www.oldhousegardens.com/display.aspx?cat=daylily&page=2

You will find that Daylilies can become the backbone of a flower garden because they are so easy to grow, bloom for weeks, and return year after year without much work on the part of the gardener.
Plus they come in all colors, single, double, tall and short. Short Daylilies are 12 to 24 inches high and there are several to choose from. Tall ones are 4 to 6 feet tall. Yes, 6 feet tall. Bloomingfields Farm Daylilies in Connecticuit has them separated by height so you can design an entire bed in layers. Click over to http://www.bloomingfieldsfarm.com/short-tall.html. They also have a link for the ones to use as groundcover, at the roadside, long blooming, season of bloom, heirlooms, new introductions and Top Ten.
Another great Daylily site is Riverbend Daylily Garden at http://www.daylily.ws/ near Xenia Ohio. You will see Daylilies on their site that you've never seen before.
Add a few Daylilies to the flower gardens, you'll be glad you did.
