Stella d Oro daylily (Hemerocallis ‘Stella de Oro’) is a popular daylily variety known for its bright yellow, upward-facing flowers. It grows in USDA Hardiness Zones 4 to 9 and has a low height of 12 to 16 inches (30 to 40 cm).
Its strap-like foliage typically reaches a length of 18 to 20 inches (45 to 50 cm). Stella d Oro daylilies are classified as “repeat-blooming” type of daylilies, meaning that they bloom multiple times over the summer and early fall on short, fast-growing blooms.
The flowers are often attractive to hummingbirds and butterflies. Stella d Oro daylilies are a carefree, low-maintenance perennial suitable for most garden settings.
How far apart do you plant Stella d’Oro daylily?
When planting Stella d’Oro daylilies, you should plant them about 18-24 inches apart. This will give the plants enough space to grow, at the same time filling in any gaps in your garden or flower bed.
It’s important to note that the spread of the plant can change with the type of soil, how much sun and water it gets, and other environmental conditions. Therefore, if you are planting more than one Stella d’Oro daylily, it is a good idea to measure out your space and adjust accordingly in order to give each plant enough room.
When planting, you should dig a hole that is slightly larger than the root ball, gently press the soil down, and water thoroughly.
Are Stella d Oro daylilies invasive?
No, Stella d Oro daylilies are not considered invasive. According to the United States Department of Agriculture (USDA), the scientific name for Stella d Oro daylilies is Hemerocallis fulva, and it is listed as non-invasive, meaning that it is not likely to spread and cause damage to other plants or wild habitats.
Stella d Oro daylilies are native to China and Japan and are commonly used in decorative gardens and landscapes. These daylilies have a clumping habit and tend to stay in place, so they won’t take over garden beds or spread into natural areas.
On average, they live for three to five years and reproduce by sending out underground rhizomes. When it comes to controlling the spread of Stella d Oro daylilies, regular pruning can help to keep the plants from becoming too large and their rhizomes from spreading.
Should you cut back Stella d Oro lilies?
Yes, you should cut back Stella d’Oro lilies. Stella d’Oro lilies are perennial plants and should be cut back on a regular basis in order to promote healthier growth. When you cut back the lilies, you can expect better bloom production in the next season.
Cutting back the lilies will also help to reduce disease, as dead leaves and foliage can harbor fungus and diseases that can spread to other plants. When you cut back Stella d’Oro lilies, you should prune them down to around 6 inches.
It is also important to cut off any infected foliage as soon as you notice it, as this will help to keep the level of infection from spreading. Cutting back lilies in late winter can also help to prevent any new buds from forming before spring, as this can reduce the overall number of blooms that are produced in the summer.
Doing so will also help keep the plants looking neat and tidy, allowing you to enjoy the beauty of the lilies for longer.
How do you keep Stella d’Oro blooming all summer?
To keep Stella d’Oro re-blooming all summer, you must provide proper care. Since this is a type of daylily, it grows best in full sun and well-drained soil. Water the plants during dry conditions and spread a layer of mulch around the base of the plant to help retain moisture.
Fertilize the plants with an all-purpose fertilizer in the early spring. This will help stimulate the plants to produce healthy blooms. In order to extend the bloom season, you must deadhead the flowers as they fade.
Simply remove the flower and cut back the foliage to the base of the plant. If the plants become crowded, divide and replant them in the early spring or late fall, being mindful to not disturb the roots.
Additionally, you can help keep the plants healthy by spraying them with an insecticidal soap when you spot any pests or fungal diseases. Follow these tips and you should be able to keep Stella d’Oro blooming all summer!.

Will Stella d Oro lilies bloom all summer?
Yes, Stella d Oro lilies will bloom all summer long! These hardy and dependable daylilies are incredibly easy to care for and thrive in a wide range of conditions and climates. Like most perennial plants, Stella d Oro lilies will bloom for many weeks throughout the summer months with proper care.
Ideal growing conditions for Stella d Oro daylilies includes full sun, well-drained soil, and regular watering. When these are met, Stella d Oro lilies will produce a profusion of large, mid-summer blooms for months that will last until the late fall season.
What happens if you don’t divide daylilies?
If you do not divide your daylilies, they will still usually continue to survive, provided they get sufficient sunlight, water, and nutrition. However, they may become less productive over time, as overcrowding and competition for nutrients can reduce their vigor.
Additionally, the flowers may become smaller and the foliage may become sparse, as the plant is expending energy on surviving instead of blooming. For these reasons, it is recommended to divide daylilies every two to three years, as this will ensure excellent performance of the plants in the long run and keep plants looking their best.
Will daylilies crowd out other plants?
Daylilies have the potential to crowd out other plants, depending on the particular circumstances. If they are planted on their own and given plenty of room to spread and reproduce, they can become invasive.
If they are planted in a garden bed with other plants, they can overtake the bed over time, creating a monoculture. If daylilies are planted close to other perennial plants, competition between the two plants could reduce both of their performances.
If they are planted in large numbers near a wider variety of plants, they may not have a major impact on most plants, as they do not grow at an overly rapid rate and will typically remain static after a few years.
However, they may still out-compete some species for space, light, and nutrients. Therefore, it is important to be aware of the characteristics of the particular plants nearby, and the potential for competition for resources prior to planting daylilies in a garden bed.
How close together should daylilies be planted?
Daylilies should be planted about 6 to 8 inches apart, with the center of one plant being about 6-8 inches from the center of the next one. If you are planting a large number of daylilies, you may need more space between each, up to 12 inches.
When planting daylilies in rows, set them on the same centerline and keep them evenly spaced. To really show off your daylilies and to take advantage of their generous blooms, you’ll want to give them plenty of space.
Never crowd the plants in garden beds, otherwise, the stems may break or bend, and the flowers won’t be able to open properly. Leave at least 18-24 inches between plants.
What can I plant behind daylilies?
Daylilies are perfect for adding beauty and color to any garden and the great news is that they are pretty easy to care for. Because they require full sun and well-drained soil, you want to plant daylilies in a spot that gets plenty of sunlight throughout the day.
When planting behind daylilies, consider surrounding them with other plants that are also partial sun-lovers, such as Hostas, Lamium, Aster, and Goldenrod. Annuals and perennials can also enhance the look of your daylilies.
Some great ideas are Bee Balm, Salvia, Foxglove, Butterfly Bush, or Columbine. Also, an evergreen shrub such as Mugo Pine or Emerald Arborvitae can be a nice addition, as it will keep color in your garden all year round.
When planting these and other perennials around your daylilies, dig a hole that is twice as wide as the root ball of the plant and just slightly deeper. This will help ensure proper drainage, especially if your soil is heavy or clay like.
Be sure to mix in some organic matter, such as compost or soil conditioner, to the soil when you plant to give your plants the nutrition they need to thrive. With the proper care, you’ll have a beautiful daylily garden you can enjoy all season.
Which daylilies are invasive?
Daylilies can be invasive in certain areas, depending on the species and environmental factors. Common species of daylilies (Hemerocallis spp.) that can be considered invasive in some areas include:
Hemerocallis fulva (tawny daylily): This invasive species is native to east Asia but has naturalized in most of North America. It can form dense colonies and may displace native vegetation in mild climates.
Hemerocallis citrina (lemon daylily): This invasive species is native to East Asia and has naturalized in many parts of North America. It easily invades disturbed areas and can also dominate roadsides and abandoned fields.
Hemerocallis lilioasphodelus (orange daylily): This invasive species is native to India and China and has become naturalized and widespread in North America. It can invade forests, meadows, and other natural habitats, displacing native vegetation.
Hemerocallis dumortieri (european yellow daylily): This invasive species is native to Europe and has naturalized in many parts of North America. It is especially invasive in established pastures, roadsides, and disturbed landscapes.
The best way to prevent daylilies from becoming invasive in your area is to choose native species that are adapted to the region and control any seed spread of invasive species. Avoiding the spread of invasive plants is important for the health of the local environment.
How do you stop daylilies from spreading?
One of the easiest and most effective way to stop daylilies from spreading is to regularly deadhead the flowers and clumps of foliage. In order to effectively deadhead, you’ll want to cut off the entire flowering stalk at ground level.
If left to bloom, daylilies will drop their seeds and can spread quickly, so checking the plant routinely for blooms and deadheading them is key. Another way to reduce or stop the spread of daylilies is to divide the plants every few years.
This will help keep the original plant in a particular area rather than having its runners spread. If planting daylilies in a more formal garden, one can also install physical barriers such as edging or mulching to restrict the growth of the daylilies.
Additionally, you can use a systemic herbicide to kill the underground spreads to stop them from traveling further. The herbicide should be applied in late winter or spring and may need to be reapplied after three months.
How quickly will daylilies spread?
Daylilies can spread quickly if planted in the right conditions. They are considered “vigorous” spreads, meaning that the rhizomes (root systems) of the daylilies tend to spread out quickly from the original planting spot.
To ensure maximum spread, daylilies should be planted in well-drained, moist soil with a pH of 6. 5-7 in full sun. Depending on the soil conditions, they can spread up to 18 inches or more in the first growing season.
The growth rate may also be dependent on the variety of daylily. Certain varieties such as Stella d’Oro tend to spread faster than others, such as the Orange Marmalade. To control the spread, daylilies should be divided (separated) every 2-3 years.
How do you get daylilies to multiply?
Getting daylilies to multiply is relatively easy and requires minimal maintenance. The most common method is to divide the existing daylilies. Typically, daylilies should be divided every three to five years, as this will help promote healthy growth and allow them to spread.
Before doing this, do some research to understand when is best for your particular type of daylily to be divided.
When dividing the daylilies, one should use a shovel to carefully dig up the entire clump, being mindful the keep the roots intact. Separate the pieces, discarding any dead or sparsely growing pieces.
They should then be replanted (about 6 inches deep and 12 inches apart) in soil that is worked with compost to promote healthy growth. Those replanted will begin to spread and build up into large clusters.
Make sure to water them often as they establish roots. Additionally, adding fertilizer regularly helps them to spread. It can take a few years for the daylilies to fully establish before they spread significantly.
