Perennial plant with rhizomatous roots, the botanical species of hemerocallis come from Asia, but for many decades these plants have been enjoying enormous success in the West, particularly in the United States, where the breeders have produced the greatest number of new varieties; the plants of hemerocallis grown in the garden are generally hybrids, the botanical species are difficult to find, also because the hybrids tend to have larger or colored flowers, and to bloom for a longer period.
From the rhizomatous roots are produced large clumps of ribbon-like leaves, slightly fleshy, elongated, often arched; these leaves are in some evergreen varieties, in others they are deciduous, and they dry up when the cold winter arrives. Starting from late spring between the leaves, thin stems, sometimes branched, rise at the apex of which some large flowers, similar to lilies, are formed, consisting of 3 large petals and 3 similar, but slightly smaller, sepals; every single flower blooms and fades within a day, but each rhizome produces numerous buds over a couple of months, making the flowering very prolonged. The "Stella d'oro2" hybrid is famous for producing its own buds from the beginning of spring to the beginning of winter.
Hemerocallids are very easy to grow plants, which tend to adapt to any cultivation condition, even if not very favorable; they are therefore particularly suitable for street furniture, or for those who know they do not have much time to devote to the garden.


To obtain a good flowering, it is essential that our Hemerocallis enjoy at least 4-5 hours of sun a day, if more it does not hurt, if instead they are placed in partial shade they tend to bloom little. The foliage alone is very decorative, and the large clumps are very suitable for low flowerbeds, but surely the flowers are the most decorative part of the plant, especially because they bloom even during the hottest and sultry summer.
These plants do not fear the summer heat, even if it is much higher than 40 ° C, and fortunately they do not even tend to the winter cold, so they are suitable for the wild, even in areas characterized by prolonged and intense frosts.


They withstand prolonged periods of drought without problems, even if sporadic watering favors flowering; generally they are watered only from April to September-October, more or less once or twice a week, avoiding to leave the soil soaked with water for a long time. Let's avoid watering the plants during the vegetative rest, or since the foliage dries up until the following spring.
At the beginning of spring we spread in the area where we have ours emerocallidi slow release granular fertilizer, specific for flowering plants; this will guarantee the right level of mineral salts in the soil.

Hemerocallids - Hemerocallis: Some tricks

Among the many existing varieties of hemerocallis (it is said they hesitate about 30000) we recall that there are different heights, from 40 cm up to about 70 cm of the highest species; there are deciduous, semi-evergreen and evergreen species; so in addition to choosing the flower of the color we prefer, let's remember to ask also for the height and if they lose the foliage, so that they can be placed at their best.
If we decide to place them in the garden, where we will leave them to grow old, we remind you that it is good to divide the roots of roots every 4-5 years, to obtain over the years luxuriant plants with a rich flowering.
For the division we choose a period from the mild climate like September-October or the beginning of the primeval one; we unearth the whole plant, with its head of roots, and produce portions of a head, making sure that we have some well-developed roots for each portion obtained. Then we plant the plants, spacing them about 35-40 cm, so that they have the space to expand. In general, for a couple of seasons the new plants will tend to bloom less than usual, but later we will have an even richer and more luxuriant flowerbed.
