Stella Daylily, Stella de Oro – A Perennial Workhorse


The Stella de Oro daylily is a beautiful and reliable daylily that will reward you with blooms all season long.    It produces bright, cheerful yellow flowers and their fragrance attracts butterflies and hummingbirds.    Its re-blooming characteristic makes it a popular perennial at Whitehouse Landscaping   and we find it to be a real workhorse in lots of landscaping situations.  They are easy to grow and make an impressive showing.

A Little History

The scientific name of this perennial plant is Hemerocallis.   The Stella de Oro is the registered name of this daylily.  It is also known as Stella d’Oro .    For the record, there are thousands of different registered cultivars of daylilies and they vary in plant sizes, flower sizes, flower colors, and flower shapes.  In fact, every year hybridizers introduce hundreds of cultivars which give gardeners lots of options to choose from.

In 1975, Walter Jablonski introduced the first re-blooming variety which he named ‘Stella de Oro’.  Up until then, all daylilies had specific peak blooming times and bloomed for a short period of time during the summer.  For the rest of the growing season, you would see the spiky green leaves.

Before their arrival in Europe in the 1500s, edible wild daylilies were used in cooking and medicine in Asia.

Characteristics of Stella de Oro Daylily

This daylily is a compact, low maintenance plant and reaches a height of about 12 inches.  The flowers are fragrant, trumpet-shaped and yellow.  Its flowers last just a day, but it will re-bloom.     It multiplies underground which forms clumps.  Its adaptability to a wide range of planting zones and conditions make it one of the most popular of daylilies.  It has vigorous growth and has an extra long bloom period.

Tips for Growing Stella de Oro Daylilies

This daylily prefers full-sun but can tolerate light shade.   Heavy shade will stunt flower production. It likes well-drained soil and performs really well in soil with plenty of compost.  But these plants are adaptable and can also perform in a wide range of soils.    Once established, it becomes drought and heat tolerant but appreciates some watering in dry spells to keep the foliage attractive.   Overall, these plants will tolerate varied conditions.  If the plants gets crowded over the years, you can divide by splitting them apart in fall or early spring.

Stella de Oro Daylily Care

If you want to keep your Stella de Oro blooming continuously, deadheading is suggested every few days. This will truly give you constant blooms and make them look neater.   It’s not absolutely necessary, but you will be rewarded with more blooms if you do.    Removing the flowers before they begin to form seeds encourages the plants to bloom again, because the plant’s energy is diverted from seed production back into bud growth.

How to Deadhead

Remove by pinching or cutting the entire flower and the ovary directly beneath it from the small stem it is growing on, or remove the flower and its stem from the main stem of the plant.  It’s not necessary to do this every day, but plan to do it every few days.

Uses in Landscaping

Daylilies solve many problems.    The foliage is attractive, forming a dense clump that can serve as a groundcover.   Because of their dense foliage, they can stabilize soil to prevent erosion on a slope.   They make great foundation plants because of their colorful blooms and foliage.  They are wonderful massed together in a planting bed or even a container.   They are considered deer resistant and rabbit proof.   They can tolerate some shade and dry conditions.


After reading all its attributes, you can see why Stella De Oro Daylilies are one of Whitehouse Landscaping favorites to plant in a variety of landscaping conditions.  We like their adaptability and are perfect for gardens, borders and edging.  They look great when planted in large masses or just a few clumps.
