Hemerocallis - Family Liliaceae - Cultivation and care of Hemerocallis plants



The Hemerocallis they are herbaceous, rustic plants, much appreciated not only for their splendid foliage but above all for their copious, colorful and almost uninterrupted blooms.BOTANICAL CLASSIFICATION





: Angiosperms


: Monocotyledons

The genre Hemerocallis belonging to family of Hemerocallidaceae (according to other authorsXanthorrhoeaceae) includes particularly hardy perennial herbaceous plants that are commonly called hemerocalli is daylily in English.

They are quite cosmopolitan plants originating from various Asian countries such as Japan, China and several other countries of north-eastern Asia but now widespread almost everywhere.

They are rhizomatous plants, that is to say they have a rhizome from which both the long and thin roots and the leaves and the flower stems are formed.

The leaves are very long, thin, very elegant in appearance and form in tufts giving the plant a very pleasant bushy appearance. Several tufts of leaves can be formed from a single rhizome. The leaves, depending on the species and variety, can be: deciduous, that is to say that they fall with the arrival of winter and the plant is completely stripped to renew itself with the arrival of spring; evergreen, that is to say that they keep their leaves throughout the year in areas with a mild climate only if the temperatures do not drop beyond certain values. There are also middle ways, depending on the temperatures.

In the central part of each tuft of leaves, two to three flower stems are formed and each bears several buds.

The flowers ofHemerocallis they are funnel-shaped that closely resemble those of lilies and have the particularity of blooming in the morning and fading in the evening (for this reason they are called beautiful during the day) but, in consideration of the fact that they bloom one at a time, in practice the plant remains in bloom for several months. The flowers are made up of six tepals (where there is no distinction between calyx and corolla the parts that make up the flower are called tepals) and the colors are among the most varied (we can find almost all colors in different shades and tones) thanks to the numerous hybrids all selected starting from the original colors which are yellow, orange and red. The only colors that have not been selected in these plants are pure white and blue. They can also be uniform in color, mottled, with different colored throats as well as the stamens and also the shape can vary from triangular, starry, flat ... in short, there are colors and shapes for all tastes.

The Hemerocallis they are particularly suitable both to be grown in pots and outside for garden borders that will remain in bloom throughout the summer.


The genre Hemerocallis includes about twenty species and a very large number of hybrids:


There Hemerocallis fulva native to Europe, it is a plant that reaches 90-100 cm in height, characterized by light green, ribbon-like leaves arranged in tufts that grow directly from the fleshy rhizome.

The flowers, very similar to those of lilies, are orange or yellow, 10 cm wide and bloom continuously at the top of a long flower stem throughout the summer, lasting only one day.

It is the most widespread and known species of which there are very many cultures that differ in the color of the flowers and in the shape.


There Hemerocallis thunbergiiis a species native to Japan characterized by narrow leaves of a beautiful dark green color up to 80 cm long with yellow flowers that appear on branched stems and are very fragrant.


There Hemerocallis lilioasphodelus it is another splendid specimen of the genus which grows up to almost two meters in height with an extensive root system and produces large yellow flowers.

Flowering is very long and lasts from late spring to mid-summer (May - July) and the individual flowers live longer than other species, even three days.


There Hemerocallis aurantiaca it is a plant native to Asian countries and has very long, shiny, thin leaves with a very elegant appearance and yellow-orange flowers slightly streaked with red. They appear at the top of long flower stems throughout the summer on very long stems (70-90 cm). There are numerous cultures among which we remember: H. aurantiaca 'Major 'with very large orange flowers tinged with red.


Hemerocallis flava it is a very widespread plant and is characterized by a flower stem up to one meter high with long, tapered leaves and very showy flowers of a very bright and slightly fragrant yellow - orange color.


There Hemerocallis dumortieri it is a vigorous plant that reaches one and a half meters in height with flower stems that carry up to eight flowers each. It blooms in late spring (May - June).


The Hemerocallis they are not difficult to cultivate plants as they easily adapt to different pedoclimatic conditions.

They love the light especially the direct sun but they also adapt to the most shady positions as long as they are guaranteed at least 5-6 hours a day of full sun. In any case, the exposure is also a function of the color of the flower.In fact, as a general rule we can say that the plants that form light pastel-colored flowers need greater exposure to direct sunlight while the cultivars that produce red-colored flowers bright or purple are better off if they don't get direct sunlight in the hottest hours of the day; this in consideration of the fact that dark colors absorb heat more and therefore tolerate it less.

It is difficult to indicate the thermal intervals within which to place the plants of Hemerocallis as in consideration of the numerous hybrids, it is impossible to give even general indications. So the advice is, when you buy one Hemerocallis, first ascertain the thermal ranges to which that particular hybrid can adapt.


For the Hemerocallis the important thing is that during the active period of growth (spring - summer) the soil always remains very humid, never let it dry out. It is preferable to do abundant watering rather than a lot of scarce watering.

It is preferable to water the plant early in the morning and not during the day.

During the autumn - winter periods, watering must be reduced just enough so that the soil does not dry out.


The Hemerocallis they should not be repotted often as they do not like traveling very much. Every 3-4 years is sufficient unless the plant has overgrown and the pot has therefore become too small to hold the roots.

The time of repotting depends on the climatic zone where it is raised. We are obviously talking about plants that must be grown outdoors. In this case, in cold climate areas it is preferable to repot in spring while in mild climate areas it can be done both in spring and late autumn.

In the event that the plant is raised indoors, repotting can be done safely in early spring.

Use a soil formed by fertile soil, peat and a small amount of sand as they grow better if the soil remains moist, contrary to what usually happens with almost all other potted plants, obviously without exaggerating as the drainage of the water must always be guaranteed.

If they have to be planted in the ground, take care to work the soil to a depth of at least 30 cm and a width much greater than the diameter of the plant so that the roots, once planted, can settle down without problems.

When placing the plant in the ground, make sure that the planting depth does not go beyond the white band that represents the transition point between the underground part and the aerial part and the planting spans must be at least 50 - 60 between a plant and the other and between the rows.


From spring and throughout the period in which buds develop, administer a liquid fertilizer with the watering water every 2/3 weeks.

It is advisable to use a fertilizer equally balanced in nitrogen (N), phosphorus (P) and potassium (K) but which also contains microelements, i.e. those compounds that the plant needs in minimal quantities (but still has need) such as magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo), all important for a correct and balanced plant growth.


The flowering periods of the Hemerocallis they are variable in consideration of the fact that there are many hybrids selected to give blooms in different periods and very prolonged in time.

In principle, we can say that the period goes from late spring to autumn.The blooms can be considered uninterrupted as, even if each flower lasts only one day, they bloom one after the other so the flowering is continuous over time. Once the flower has faded it must be removed immediately.


There Hemerocallis it is a plant that cannot be pruned. It is only necessary to eliminate the leaves that gradually dry up.


The Hemerocallis multiply by division of the tufts.


At the beginning of spring in the cold climate zones or even in autumn in the temperate climate zones, you can divide the tufts of the plant and plant them in a compote as indicated in the paragraph "repotting" and then treat the plant as if it were an adult.


Very rarely the Hemerocallis they are subject to parasitic attacks more than anything else if they show states of suffering, they are due to bad cultivation techniques.

The plant withers and manifests a state of general decay

This symptom is certainly due to the fact that he has allowed the soil to dry out.
Remedies: you must regulate the watering of the plant so that the soil always remains wet during the growth period and moist during the other periods.


Their name Hemerocallis comes from two Greek words χάλός «beautiful andήμέρά «Day», «beautiful during the day» because flowers last only one day, blooming in the morning and fading in the evening.

They are plants that are spreading very quickly thanks to the beauty not only of the flowers that, thanks to the selection, are always larger and variously colored but also for their long, tapered and very elegant leaves.

There are some types of Liliaceae noteworthy and necessary in a modern garden.

Among these we point out the Fritillaria, a bulbous South African with showy flowers, and the least known Tricyrtis (in the formosa and hirta varieties). It is about rustic rhizomatous plants, which grow spontaneously in the territories of the Himalayas and the Philippines.

They have star-shaped blooms and are well suited to shady and humid areas, as long as the substrate is well drained.

Hemerocallis: description of the plant

Belonging to the family of Liliaceae, L'Hemerocallis or Hemerocallis, it's a bulbous perennial. The genus includes over 3000 varieties, all different.

The leaves they are ribbon-like, up to 70 cm long, very reminiscent of tufts of grass. From summer to autumn, the stump of leaves leave the drums fleshy and erect, rich in buds. Considering that each stem is rich in flowers and that these develop one after the other, the overall flowering can therefore last several weeks.

THE flowers they are made up of six petals, curved outwards. Colors range from red all 'Orange, until the yellow and shapes can vary from funnel to triangular. They are very reminiscent of the lily.

Over the years, market needs have favored the spread of numerous hybrids, with more multicolored colors, even streaked and two-tone. Let's now discover some of the best known varieties.

Variety of hemerocallis

Among the different varieties available here are the main ones:

  • Citrine: smells of lemon and its flowers are yellow. It can even reach 80 cm in height. It blooms between June and July and is native to China.
  • Aurantiaca: reaches 85 cm in height and produces orange flowers. It is originally from Japan.
  • Golden Star: this is a dwarf variety, therefore suitable for growing in pots or for creating small borders. It does not exceed 40 cm in height and its flowers are golden yellow.
  • Flava or golden lily: we are talking about a variety originally from Siberia and Hungary. 60 cm tall, it produces very fragrant and yellow flowers.
  • Fawn or Turkish lily: the flowers are characterized by the presence of streaks that adorn the orange petals, tending to red. We find it originally in China and it reaches 75 cm in height.
  • White Temptation: deciduous, the flowers are of a very delicate yellow, close to white. Ideal for those who live in areas with severe winters, since it also tolerates frosts.
  • Jolyene Nichole: this variety of hemerocallis has curled, pink petals.
  • Prairie Blue Eyes: from the name itself, it is characterized by the blue tone of the petals and the light yellow throat.
  • Little business: this is also a dwarf variety, with red flowers and a green and yellowish throat.


The flowering of Hemerocallis usually takes place between May and October. We talk about uninterrupted flowering, since the dance we were talking about before continues for a long time, giving new flowers with bright colors every day. These are, in shape and scent, similar to those of Lilies, but with the particularity of the daily duration.

Although it may appear as a delicate plant, Emerocallis can incredibly resist high temperatures (and long periods of drought) and the coldest ones.

In short, the perfect plant to give not only a touch of color to the flower beds in the garden, but also to give the feeling of life, movement, harmony. All in a very setting rustic. The flowers follow one another in a continuous way, as well as the butterflies and hummingbirds, which will never stop resting on the elegant flowers.

Hemerocallis var. Michael Bennet - Daylis

The genre Hemerocallis includes about 15 species of perennial, evergreen or semi-deciduous plants, native to China, Korea and Japan. In nature, in the native countries, they are widespread in the most illuminated clearings at the edges of the forests, in the mountainous areas or in the marshy valleys. They have been cultivated for a long time, so much so that they are well known 30,000 cultivars. They almost always form thick tufts, but they can also be rhizomatous. The Greek root of the name (hemera day and kalos nice) remember how much it is the life of a flower is short of daytime, commonly called also "beautiful by day", contracted form of "beautiful for a day". Michael Bennet was selected in 1985.

Leaves: I'm arched, dark green, up to 50 cm long.

Flowers: color deep purple, they have one streak lighter central and stamens of the same color with pollen intense yellow, they are carried on stems longer than the leaves. Usually they last one day, at most two, and the plant produces numerous buds so that flowering lasts for two or three weeks.

How to choose it: prefer well-branched, vigorous, healthy plants, without signs of mold or softening, if possible with a flower to identify it the variety, without caring too much about the production in the first year because it is over time that the hemerocallis give their best.

Diseases and Parasites

Lilies fear root rot caused by water stagnation and the attack of aphids, which particularly prefer flowers that are still in bloom.

You use lilies

Lilies are grown for the trade of cut flowers and for ornamental purposes to embellish flower beds and gardens.

THE St. Anthony's lilies for their meaning of "purity" they are used for the day of the Communion of children and for their blessing on June 13th.

Lilies are also widely used for the preparation of packages for weddings, banquets and to set up brides' bouquets.

Lily and the language of flowers

In the jargon of flowers, the lily symbolizes purity.
