Daylilies are not real lilies; they are members of the genus Hemerocallis. This Greek word’s two components are hemera, which means day, and kallos, which means beauty. The name fits because each flower only blooms for a day.
Flowers on some of the more recent kinds open in the evening and stay open into the evening of the following day. Many of these plants that bloom at night have wonderful fragrances.
Daylilies typically reach a height of one to four feet. Each daylily plant generates a large number of flower buds that take a while to open. The flowers continue to bloom throughout the sweltering summer since there are so many different kinds and a large variety of floral hues.
What daylily grows the tallest?
Gardeners may overlook certain plants because they are overused or have a bad reputation in an effort to build a garden that stands apart from the norm. The same is true of daylilies (Hemerocallis spp. and cvs.). We’ve seen them rejected from planting lists due to their excessive refinement or ostentation, short stature, lack of long-season appeal, and a host of other issues. One of the most varied and extensively hybridized perennial flowers is the daylily. Over 60,000 registered varieties with different flower forms, sizes, and color combinations are recognized by the American Daylily Society. Given these findings, it is difficult to think of anything else that would be novel or distinctive about a daylily.
However, some aspects of daylilies are disregarded, such as the finer points of the foliage and scape (flower stem). While maintaining their image as low-maintenance plants, species and some cultivars with intriguing leaves, incredible scape height, or unexpected bloom period can dazzle us in unusual gardens.
The toughest of the difficult daylilies are ideal for any environment that isn’t ideal for growing flowers. Forget about the extra care that so many of the more modern, spectacular daylilies require. They can take a little while to establish themselves and reach their full splendor, but once they do, they are practically unbreakable. They can withstand periods under water and even outcompete tall weeds like goldenrod because of their excellent drought tolerance.
Hemerocallis citrina has trumpet-shaped, lemon-yellow flowers that are typically fragrant. There are many different species, in part due to the fact that the original species has been farmed for such a long time that it is challenging to determine which varieties are real species types descended from the wild or early hybrids that arose spontaneously or through hybridizing. The scape height, flower type, and bloom period are some of their variances.
The H. citrina species come in a wide variety of flower shapes and colors, from spidery to trumpet-shaped blooms. As they all appear to be resistant to leaf diseases, you can rely on them for their exceptional foliage that always stays immaculate. All have blue-green glaucous leaves, and the springtime new shoots have dazzling, luxuriant coloring that is noticeable from a distance. Around the base of the plants, the leaves wither in the fall to form a lush, weed-repelling mat.
The H. citrina complex includes Hemerocallis citrina var. vespertina, H. c. var. thunbergii, and potentially H. altissima. These daylilies are extraordinarily tall, reaching 48 inches or higher and having more than 20 buds on each scape. The traditional H. citrina has about 20 buds and a scape height of 48 inches. The foliage is usually a bluish green and stands approximately 24 inches tall. H. citrina blooms in the middle of the season (mid-July in Vermont), and they continue into August. The vespertina variety grows larger, reaching heights of 6 feet in scapes and 35 in buds. The vegetation is thirty inches tall. H. citrina appears quite similar to H. c. var. thunbergii, but it has 6-foot scapes, 35 bud counts, and blooms from late July to late August.
The complete opposite of that
The season’s first bloomers are the early-blooming species. All are resilient and trustworthy, and they are commonly suggested to hide the ugly leaves of dead daffodils. One of these ancestor species is Hemerocallis dumortieri. In Vermont, it normally blooms in early June but might bloom as early as late May. For a daylily, its trumpet-shaped yellow-gold blooms are surprisingly aromatic.
reaching further higher The obvious strategy is to combine the several H. citrina kinds and pick the best-looking seedlings that result. Many exceedingly tall cultivars have been created through hybridization. Old favorites like “Autumn Minaret” and “Challenger,” created in the 1930s by Dr. Arlow Stout, come to mind. Here in Vermont, we have concentrated on traits resembling the species but with particular chosen features.
H. c. var. thunbergii hybrid “Towers of Eisenkramer” towers at six and a half feet and has open flowers that are a bright yellow color. Towers of Eisenkramer is extremely productive (as are the species), but occasionally flops under the weight of its seedpods.
Two well-known tetraploid varieties are “Notify Ground Crew,” which has yellow five-inch blooms on six-foot scapes, and “Berlin Tallboy,” which has orange six-inch blooms on six-foot scapes. Due of their strong resemblance to the species, colors other than yellow, gold, and orange are uncommon. A rare tall red daylily from Germany named “Berlin Red Tallboy” is not well-known in the United States, and as a result, nothing is known about it at the moment.
Dark terrain The colored scapes, buds, and bracts of daylilies are another underappreciated feature. Scales with a high pigment content can be created by selective breeding. ‘Sir Blackstem’ is one of several later flowering dark-scaped cultivars, however the most traditional pigmented scape cultivar is described as an early bloomer with an evergreen growth habit, reaching a height of 24 inches. ‘From Darkness Comes Light,’ an early bloomer with creamy yellow flowers, is another daylily with a dark scape.
H. dumortieri appears to produce the daylilies with the most intense pigmentation. Two cultivars that have no names as of yet other than the designations “4-9-01” and “17-08” are examples of the range of coloration that is possible. The first is extra-early blooming since it blooms in early to mid-June and is lemon yellow with dark scapes. With deep matt black scapes and a richer golden bloom, “17-08” stands out. Long before the flowers ever open, its growth habit, which is somewhat undulating, creates a breathtaking display. The scapes start out green, but as they are exposed to sunshine, they gradually turn darker and darker until they take on the strong dark hue that is so remarkable. It’s interesting to note that the pigmentation is promoted by sunlight.
Daylilies with crimson blooms and dark scapes are also common. Although it is unclear who their parents are and what color they are, the effect is still very noticeable. It is conceivable that selective breeding will eventually produce dark-scaped daylilies with a range of bloom hues. After all, there are novelties in daylilies.

Does the daylily spread?
Daylilies grow more and more crowded as they quickly form larger clumps, which finally prevents them from blooming as well. Every few years, you might want to divide your daylilies, especially if you observe fewer flowers.
How big and how tall do daylilies get?
The height of a daylily clump can range from six inches to five feet. Space bare roots about three feet apart since they can grow to a span of two to four feet wide (or for a more dramatic show in the early years, space about 18 inches apart).
Which daylily has the longest blooming period?
AKA “Miss Amelia” This daylily is the one for you if you’re seeking for a profuse long-bloomer. For more than three months, every plant produces an abundance of aromatic blossoms! Additionally, “Miss Amelia” multiplies swiftly, allowing you to quickly create a lovely mass.
How can I ensure that my daylilies bloom all summer long?
The ever-blooming Stella D’Oro daylily is shown here. Basically, this perennial’s show of golden, yellow flowers will start in May and continue up until a strong winter. You will get more blooms if you deadhead them (take the old flower stalks off at the base) as opposed to if you let them grow into seed pods that will mature over the summer and burst in the fall.
Although it is not required, doing it will improve your performance. And let’s face it: floral power is crucial in a perennial garden!
Can daylilies flourish in tree shade?
When selecting companions for daylilies, there are a few fundamental rules to keep in mind. First of all, as daylilies enjoy full sun or at least very light shade, any plants that are companions to daylily plants should have comparable needs. However, be careful not to grow anything taller than your daylilies or you risk unintentionally shading out your sunny position.
Stick to plants that enjoy similar conditions, such as daylilies, which prefer rich, well-drained soil that is somewhat acidic. Daylilies shouldn’t be planted close to trees since the shade will hinder their growth and the roots will obstruct the lilies’ own deep root system.
How many daylilies can you plant in a single planting?
I had a variety of roles as a founding worker at Gardener’s Supply over the years. I currently run my own business, which is called Johnnie Brook Creative. A huge vegetable garden, a seasonal greenhouse, a cutting garden, perennial gardens, a rock garden, a shade garden, berry plantings, numerous container plants, and a meadow garden are among the gardens surrounding my Richmond, Vermont, home. The garden is the only place I would rather be. Check out this Garden Gate magazine video interview from January 2021 if you’re interested in learning more.
The daylily is the only perennial that can be considered a “guaranteed thing.” They do well in zones 3 to 9 (from Minnesota to Florida), can survive a wide range of soil types, are unaffected by diseases or pests, and consistently bloom for years with hardly any care. Hemerocallis, the daylily’s botanical name, literally translates to “beauty for a day,” and in fact, the majority of daylily flowers open in the morning and wither by dusk. The plant blooms for several weeks because each flower stem, also known as a scape, often bears at least a dozen flower buds.
Daylilies, unlike the majority of perennials, can be used in a variety of ways in the garden and landscape. The shorter, more compact kinds grow nicely when planted straight into perennial borders, where their blossoms provide the landscape a much-needed lift in the middle of summer. Daylilies are best planted in groups of three or five for landscapes, especially when combined with tiny shrubs and decorative grasses. Daylilies make the ideal plant for mass plantings along fences or walkways since they create a weed-free display that is thick and attractive.
Planting Instructions
Daylilies need 4-6 hours of direct sunlight every day, thus they should be planted in full sun or mild shade. Even though daylilies require full sun, there are occasionally blossoms under the cover of large trees. The daylily blossoms will always face away from any shadow and upward toward the sky. Avoid high dry locations above ledges where the soil is shallow and low wet spots where water collects during rainy spells.
Any time the ground can be worked, whether it’s in the spring, summer, or fall, daylilies can be planted with great success. To avoid winter frost heaving, mulch should be applied to daylilies planted in the fall. We advise you to plant your daylilies as soon as you get them. The roots should be placed in water for an hour before planting, but, if they will be stored for several days.
Approximately the size of the pot, dig the hole. Remove the daylily from the pot, untangle the roots, and set it into the hole with the surrounding dirt tightly packed.
Until you are ready to plant, keep in a cool area. Roots should be soaked in water for an hour prior to planting if kept for several days. Create a hole and place a cone of earth inside. Cone-shaped roots should be spread out, and the crown should be slightly below ground. One inch of earth should be pressed down tightly around the plant’s crown. Give newly planted daylilies plenty of water.
The best soil is loose, loamy soil. Clay, gravel, and sand quality is very low. Compost, decaying leaves or wood chips, old manure, or almost any other organic substance can enhance poor soil.
If the daylily will be divided and replanted in a border of mixed perennial flowers in three to five years, leave a circle of 16 to 18 inches in diameter. It needs a 24–30 inch spacing if you plan to leave the daylily clump in place for 10–15 years. A border of daylily flowers follows the same rules. Daylily plants should be placed in a triangle configuration with each plant 24 inches apart from its neighbors in a landscape setting, such as a bank that will be covered in the flowers. 30 daylily plants will consequently be needed for a bank that is 100 square feet. (Add 0.304 to the square footage.) Plant the daylily seeds 12 to 18 inches apart in a straight line as an edging along a walkway.
Mulch between one and four inches thick will help keep the soil moist and prevent weeds from growing among the daylily plants. While grass clippings, leaves, hay, wood chips, and other organic materials are appropriate, their slow breakdown draws nitrogen from the soil. Particularly with recently cut wood chips, you might want to add some fertilizer. Daylilies planted in the fall should have a thick layer of mulch applied to the area the first year to keep the earth from freezing and heaving them out of the ground.
Plant nutrients are rarely insufficient in organic compost soil. Add any slow-releasing, composted organic matter, such as horse, sheep, or cow manure, or your own compost, in the spring or the fall to sustain good daylily growth.
What distinguishes lilies from daylilies?
Lilies and daylilies share the same term “lily” in their names, leading to frequent confusion about which flower they are or that they are related. This is untrue; the two species have no connection to one another. True lilies have the scientific name (Lilia), while daylilies belong to the (Hemerocallis) family (Lilium). It is sometimes simpler for a gardener to identify which “lily” (s)he is dealing with thanks to certain traits. (A field of daylilies is depicted in the image featured above.)
The following is a list of their variations:
- The first difference you will see when planting these flowers is that daylilies grow from tubers (rhizomes), whereas lilies grow from bulbs.
- Three petals and three sepals make up the top layer of a daylily’s two stages of flowering. There are six petals on a lily constantly.
- Examining their leaves will help you tell the two apart easily. A daylily plant’s leaves resemble grass blades that are emerging from a clump. Lilies, on the other hand, have leaves that extend the whole height of the central stem. They will resemble spirals or whorls.
- Daylilies often reach their tallest point at about 4 feet. Lilies can reach heights of up to ten feet.
- Since daylily blooms only endure one day, they are not appropriate for bouquets. Lilies have blooms that can last up to a week and are frequently used as cut flowers.
- The blossoms of daylilies are tasty. Lilies are poisonous in every aspect, especially to cats.
Lilies and daylilies are different even though they have the same common name. Hopefully, this knowledge will clear up any doubts one may have regarding these gorgeous garden plants.
