Stella D’Oro Daylily (also known as Stella de Oro) is a reblooming, dwarf miniature daylily with beautiful 2 3/4″ canary-yellow flowers and lightly ruffled petals. This tried-and-true standby is great for masses, borders, and restricted sites where maintenance is difficult or undesired. Stella D’Oro Daylily is one of the most popular Hemerocallis cultivars available due to its long blooming period and adaptability.
Stella D’Oro Daylily is an excellent choice for borders or mass plantings, especially in sites where low maintenance and continuous flowering are desired. Make sure to leave spacing for these plants as they will fill out with age. Its smaller habit also works well in rock gardens.
The canary yellow flowers of Stella D’Oro Daylily will attract hummingbirds and butterflies, although this plant is not of significant importance to any particular animal species.
The spent flowers of Stella D’Oro 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 Stella D’Oro 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.
Stella D’Oro Daylily should be divided every 3 years in spring or fall 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, and Stella D’Oro Daylily is no exception. Mites, aphids, and thrips may occur, but these problems are exceedingly rare. Slugs and snails may also be problematic at times, but daylilies in general 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.
Daylilies are put into one of three categories depending on their flower size; miniature daylilies, such as Stella D’Oro, 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.
Stella D’Oro Daylily will pair well with Russian Sage, Catmint, Hummelo Lambs Ear, Rozanne Geranium, and Strawberry Seduction Yarrow. When siting, make sure you leave adequate spacing between plants to avoid overcrowding and make division easier.
