Hemerocallis citrina - Daylily

Hemerocallis citrina, also known as Daylily, is a wonderful botanical species that should be included in every perennial-lover's garden. Among the tallest of its kind, it stands out with its large sculptural flowers: authentic lemon-yellow trumpet-shaped blooms that open at the end of the day giving off a stunning lily-of-the-valley scent. This superb perennial blooms in the height of summer and again in September, above a fine foliage gathered in a magnificent cluster. The visual and olfactory ballet it reproduces year after year will astonish gardeners. It should be given a fertile and deep soil, as well as occasional watering in case of a dry summer.

Hemerocallis citrina is a deciduous perennial plant with fleshy roots, belonging to the Xanthorrhoeaceae family. It is native to East Asia and China, where it grows on the edge of forests, in meadows and on grassy slopes at altitudes below 2000 m (6560 ft). This daylily quickly forms a dense clump, reaching a height of 80 cm (32 in) to 1.2 m (4 ft) depending on the growing conditions. Its leaves are narrow and linear with a fairly dark green colour but are still very vibrant in spring. Flowering takes place in July-August, and again in September. The flowers, a tangy yellow, are 15 to 17 cm (6 to 7 in) wide and form an elongated trumpet that opens like a star. Each flower has 6 slender petals surrounding a bunch of long, curved stamens, which are also lemon-yellow. These ephemeral flowers only live for a day, but they continuously renew themselves on tall, thin yet sturdy stems, well above the foliage. The foliage turns yellow in autumn before disappearing.

Hemerocallis citrina creates grandiose masses when planted in groups, especially since it grows rapidly. It is best placed at the back of a border, as its beautiful foliage disappears in winter, leaving only a tangled straw carpet on the ground. It pairs well with blue or mauve flowers such as Malva sylvestris, delphiniums, anchusa, or large perennial geraniums (Geranium magnificum, G. psilostemon). It is very easy to grow and thrives in both partial shade (in hot and sunny climates) and full sun. The daylily is often called "the perfect perennial plant" due to its vibrant colours and its ability to tolerate any type of environment, as well as its beautiful exuberance that complements other perennials.

Plant botanical and hybrid daylilies in generous clumps at the back of your borders. All summer bulb flowers can be planted alongside daylilies. On a balcony or terrace, large pots of at least 40 cm (16 in) deep should be used, and dwarf varieties should be preferred. The flowers, stems, and roots are edible.
