Suggested Uses:

Use Rocket City Daylily as a mass planting in large beds or along slopes where erosion is problematic. Its large size works well as a focal point in mass plantings mixed with other perennials. It can also serve as an informal border between different areas due to its greater height.

Wildlife Value:

The showy, large flowers of Rocket City Daylily will attract a wide variety of hummingbirds and butterflies, although this plant is not of significant importance to any species.

Maintenance Tips:

The spent flowers of Rocket City Daylily can be deadheaded to keep the plant looking tidy. The dead flower stalks, called scapes, can be pulled once they’ve completely dried. In spring, the leaves and stalks of last year can be cleaned up to keep your bed tidy.

While drought tolerant, watering Rocket City Daylily during drought will keep the foliage full and attractive. In periods of low moisture, some foliage may brown out and become unattractive. These damaged parts of the plant can be removed once supplemental water has been provided.

Rocket City Daylily should be divided every 3 years in spring to improve flowering and reduce crowding. Dig up the clump, remove ½ to ¾ of the mass, and replant the remaining portion. Water well after replanting to develop a healthy, deep root system.


Daylilies are generally pest and disease free. Rust, mites, aphids, and thrips may occur, but these problems are exceedingly rare. In general, Daylilies will be happy and healthy as long as they are able to establish and receive adequate sunlight.

The flower buds are tasty fodder for deer, especially in periods of drought when other food sources may be unavailable. If excessive browsing is problematic, a repellent spray or fence may be used to protect the flower buds.

While the Daylily Rust fungus is of concern in southern states, the fungus has not been observed to successfully survive our cold winters in the Midwest.

Leaf Lore:

Daylilies are put into one of three categories depending on their flower size; miniature daylilies, that have flowers that are 3 inches or less in size; small daylilies, which have flowers that are between 3 and 4 ½ inches; and Large daylilies, with flowers greater than 4 ½ inches in size.

Daylilies are native to Asia and Central Europe and were brought to North America as a hardy ornamental. While over 55,000 registered cultivars exist, no one has successfully created a cultivar with pure blue or white flowers. The current focus of many selection and hybridization programs is to develop cultivars with better hardiness and unique flower traits. With so many cultivars available, we try to stock only those cultivars that have proven themselves in our climate and soils.

Daylilies get their name from their flowering habit. A single flower will last one day, opening in the morning and withering at night. However, the plants produce huge quantities of flower buds and the spent flowers are quickly replaced the following day.

Companion Plants:

Blend Rocket City Daylily with Russian Sage, False Blue Indigo, or Catmint for varied texture. It can also be placed behind a border of low perennials like Rozanne Geranium, Moonshine Yarrow, or Prairie Dropseed.
