All About Daylilies

By Judith Irven, gardening expert, landscape designer and writer.

Daylilies: Stars of the Summer Garden

Daylilies are the gardener’s dream-come-true:

Luscious flowers in a kaleidoscope of colors
Easy to grow
Long-lived
Bloom times from early summer to early fall
Most varieties hardy throughout the United States and southern Canada (Zone 3- through Zone 9)
Thrive in a wide range of conditions— from cool hollows to dry hillsides

An ancient plant becomes a gardener’s delight

All the daylilies we grow in our gardens are descended from just seventeen species of ‘original daylilies’ that are native to eastern Asia, primarily in Japan, Korea, Mongolia and China, where they were also cultivated for many years.

These seventeen species (which are only distantly related to ‘true’ lilies) are grouped into the single genus Hemerocallis, which means ‘lovely for a day’ - a reference to the fact that each individual flower blooms for just a single day. About 400 years ago, plant explorers introduced a number of these daylily species to Europe and eventually to North America.

One introduced species is the familiar ‘Orange Daylily’ (Hemerocallis fulva) that now blooms with ease along country roadsides all across North America. But beware: in some states it is considered invasive. And it's not advisable to plant Orange Daylilies in your garden since, with the help of their strong underground runners, they will soon overrun everything else. They are, however, a perfect choice for hiding ugly building foundations and filling ditches.
Another introduced species is the old-fashioned ‘Grandma’s Lemon Daylily’ (Hemerocallis lilioasphodelus) which still can still be found growing around the old farmsteads and cellar holes in the mountains of New England. With its early bloom time and lovely lemony fragrance, a small patch of Lemon Daylilies makes a welcome addition to any garden.

Seventeen species: the hybridizer’s starting point

Over the last seventy-five years, these seventeen daylily species have become the basis for hybridizers everywhere to try their hands at creating new varieties of daylilies. Depending on their native habitat, daylily species exhibit a variety of traits that can be exploited by hybridizers.

For instance, some species come from the mountains, meaning they will be quite hardy and will most likely go dormant in the winter. Others dwell in low lying areas and, while less hardy, keep their leaves year-round.

Some species have quite tall flower stalks (scapes), whereas others are extremely short. And their flowers range in color from pale yellow to strong orange and reddish, all the way to deep maroon.

Today: a multitude of cultivated varieties

Eventually daylily hybridizers—both professional and amateur—have created the array of cultivated varieties of daylilies that are available to gardeners today. These include multi-colored extravaganzas as well as daylilies with extra long bloom time. It is estimated that the number of different cultivated varieties (or cultivars) of daylilies now runs in the hundreds of thousands.

Daylilies make your garden come alive

One of the easiest ways to energize your garden is to combine daylilies, with their huge blooms, and other favorite perennials that will bloom at the same time.

And, with their striking flowers, daylilies create a dramatic textural contrast when grown alongside ornamental grasses such as Blue Fescue, Blue Oat Grass, Tussock Grass and Switch Grass.

Some varieties of daylilies are quite petite, so that two or three plants grouped together would make a lovely accent near the front of the border. Plant these with other short plants such as Nepeta (Catmint), Blue Fescue and Blue Oat Grass.

Other daylilies have flower stalks that grow over 30 inches tall, and these will stand out in the middle of the border alongside Echinacea and Rudbeckia, all mixed in among some clumps of airy, Tussock Grass. The whole composition can then be completed with a backdrop of taller Switch Grass.

American Meadows Flower Power Daylilies

The latest advances in daylily hybridization has brought us a whole range of new varieties which bloom multiple times in the course of the season - vastly increasing the number of flowers that each plant creates each season. These are known as repeat blooming daylilies, or reblooming daylilies.

With these new daylilies, plus a little extra care (additional fertilizing and the removal of spent leaves and seed capsules, plus irrigation during dry periods), gardeners can enjoy flowering daylilies all season long.

At American Meadows, we are incredibly excited to bring you twelve different re-blooming daylily varieties with beautiful colors and amazing flower production. After a few years, as your plants mature, you can look forward to enjoying hundreds of blooms on a single plant over the course of a single season.

A rainbow of colors to excite your imagination

Our Flower Power varieties come in a multitude of gorgeous colors to stimulate your creative genius.

For instance, all our single-colored Power Bloomers—Space-coast Early Bird, Lacy Doily, Heavenly Pink Fang and Bakabana— grow less than 2 feet high and introduce soft warm colors like pink, peach and yellow to the garden.

So interspersing any one of these among clumps of Nepeta ‘Walker’s Low’ (also long blooming), or some Blue Fescue Grass or Blue Oat Grass, would produce a beautiful, enduring contrast of both color and texture for the front of the border.

Or how about creating a long-blooming multicolored extravaganza by planting some or all of these multi-colored beauties en masse:

Daylily Variety	Coloring
Night Whispers	Red with yellow throat
She’s Got the Look	Pale pink fading to creamy center
Simmons Overture	Pink outside, burgundy then yellow throat
Moroccan Sunrise	Crimson red with yellow throat
Magic Dancer	Crimson red, burgundy and yellow throat
Irresistible Charm	Red frilled outer rim, yellow and red center throat
Lavender Tutu	Yellow frilled outer rim, peachy lavender then yellow throat
Entrapment	Lilac with yellow highlights
