How to grow and care for Day Lilies?

Day lilies are no longer seen as simple, ordinary garden plants. While they remain popular for being hardy and easy to grow, modern varieties have introduced a spectacular range of colours, shapes and patterns that make them standout features in any garden.

Today’s day lilies are available in shades ranging from soft pink and lavender to rich red, russet and deep purple. Some varieties feature a striking ring of colour around the throat, known as an eyezone, while others have petals edged in contrasting tones. With so many new cultivars available, day lilies are becoming a favourite for gardeners looking for long-lasting colour and low-maintenance beauty.

Why are day lilies so popular?

One of the biggest advantages of day lilies is their long flowering season. They provide reliable colour from October to May, making them a valuable addition to South African gardens. Although each individual flower lasts for just one day, a healthy plant can produce more than 50 blooms in a single season.

Day lilies are also highly versatile. They work well in flower beds, borders, mixed perennial plantings and containers. Once established, they need very little attention, making them ideal for both new and experienced gardeners.

Best growing conditions for day lilies

• Day lilies grow best in a sunny position and need at least five hours of sunlight each day to flower well. Darker-coloured varieties benefit from a little afternoon shade, as strong sunlight can cause the flowers to fade.

• They adapt to most soil types but perform best in rich, fertile, well-prepared soil. Before planting, improve the soil with plenty of compost and bone meal to encourage strong root growth and healthy flowering.

• Dormant day lily varieties are better suited to colder climates, while evergreen varieties usually perform better in hotter areas.

How to plant day lilies correctly

Correct planting depth is essential for healthy day lilies. The crown should be placed level with the top of the planting hole so that, once the soil settles, it sits about 2 cm below the surface. Planting too deeply can reduce flowering and affect growth. After planting, water thoroughly to help settle the soil around the roots.

Day lily care and maintenance

• Once established, day lilies are easy to care for and fit well into low-maintenance gardens. Increase watering when the leafless flower stems, known as scapes, begin to appear. These rise above the foliage and carry the flower buds.

• Most scapes branch into two or more stems, each producing several buds. Some gardeners remove the earliest scapes to strengthen the plant and encourage better blooms later in the season.

• To keep plants healthy and flowering well, feed them at the beginning, middle and end of the growing season with a 5:1:5 or 3:1:5 fertiliser. Day lilies grown in pots should be fed every ten weeks.

How to propagate day lilies

• Day lilies are easy to multiply. Small plantlets sometimes develop on the flower stem during blooming. These are called proliferations and can be removed and potted once the scape has finished flowering.

• Established clumps can also be divided in autumn. This is one of the easiest ways to propagate day lilies, refresh older plants and share them with other gardeners.

Interesting facts about day lilies

• Although many gardeners still write the name as two words, day lily is often written as one word, daylily.

• Day lilies belong to the genus Hemerocallis, while true lilies belong to the genus Lilium.

• There are more than 30,000 named day lily cultivars registered internationally, showing just how popular and diverse these plants have become.

• In ancient China, the roots, leaves and flowers of day lilies were used as food, while the roots and crown were also valued for traditional medicinal purposes.

If you are looking for a plant that offers vibrant colour, long flowering periods and easy care, day lilies are an excellent choice. With the huge range of modern varieties now available, these dependable plants can add interest and impact to almost any garden setting.
