Caring for Your Hemerocallis (Daylilies)

100_8376

Daylilies produce an abundance of showy, funnel-shaped, lily-like flowers atop slender flower stalks called scapes in early to mid-summer. Through extensive breeding efforts, there is a vast array of flower colors and combination of colors available today. Nearly every color is available including various hues of carmine, lavender, maroon, orange, pink, red, rose, scarlet, and yellow.

Hemerocallis cultivars are most commonly marketed by their blooming characteristics. They are commonly categorized into groups by the time of the year they bloom. Early bloomers typically bloom in June, mid-season bloomers flower in July, and late bloomers do not flower until August. Daylilies are also categorized by the length of time they bloom. Repeat bloomers (rebloomers) produce an initial flush of flowers in the late spring or early summer and will have at least one additional flush of bloom later in the growing season. Hemerocallis categorized as extended bloomers produce flowers that remain open at least sixteen or more hours per day.

With their reliability and beauty, daylilies have the reputation of being one of the toughest, most adaptable perennials used in the landscape.

Growth Habit: Daylilies form attractive clumps of arching, sword-like foliage of various sizes ranging from 12 to 30 inches tall by 12 to 24 inches wide. When blooming, the flower scapes commonly reach 12 to 36 inches tall.

Preferred Conditions: Hemerocallis prefers to be planted in landscapes with fertile, moist, well-drained soils. They grow best in locations with full sun to partial shade. Once established, daylilies can withstand heat and drought better then most commonly grown perennials. Conversely they can tolerate sites that occasionally are wet, but do not perform well in consistently water logged soils.

Planting & Maintenance: Containerized daylilies can be planted throughout the growing season, but are most commonly planted in the spring or the fall. They should be planted even with or just slightly higher then the soil line.

Generally considered easy to grow and require little routine maintenance. In fact, once established they need virtually no care. To maintain a clean and attractive appearance, many gardeners remove the flower stalks once the blossoms have faded. Mulching during the summer months will help keep the soil moist. Many gardeners remove withered, dried foliage form the beds in the fall to keep the beds looking nice and to keep the plants disease free. If the clumps become too large, they can be divided every 3 to 4 years.

Uses in the Garden: Hemerocallis are commonly used as accent or specimen plants, in borders, and as edging plants, ground covers or mass plantings.

Other Uses and Attributes: One of the biggest attributes is they require virtually little care; in fact, they thrive with little to no attention. Once established, daylilies are drought tolerant and perform well across a wide range of growing conditions. When blooming they attract butterflies and hummingbirds into the garden. These tough plants are also resistant to deer and rabbit feeding.
