The daylily is practically disease- and pest-free, easy to grow, and resilient to drought, shade, and poor soil, making it the ideal perennial. Discover how to cultivate daylilies and quickly propagate them for extra plants!
These plants, which are originally from Asia, have adapted so successfully that many of us consider them to be locals. Imagine how thrilling it would have been for a 16th-century traveller to tour the Orient and discover these beautiful flora! Daylilies were welcomed into European gardens by gardeners, and they traveled to the New World with the first colonists.
Daylilies have a long tradition of being used in both gardens and kitchens. The delicate foliage was used as a spring green, the buds and blooms were added to soups and consumed raw, and the swollen parts of the root were cooked and consumed. When cooked in stews, soups, or sauces, all sections have a mild peppery flavor and serve as a thickening factor.
Considering that each blossom only lasts for one day, their botanical name Hemerocallis means “beauty for a day.” Daylilies grow from fleshy roots instead of genuine lilies’ bulbs, and their flowers appear on scapes that are leafless and rise above the leaves. One of the 12–15 buds on each scape opens every two days. With 4 to 6 scapes on an adult plant, there is a lengthy bloom time. Some plants can grow up to six feet tall, measured by the length of the scape!
Divide the daylily clumps before the autumnal equinox in late summer or early fall after flowering (late July to mid-September) in order to multiply them. Before winter, the plants need at least six weeks to reestablish themselves.
Even though many gardening guides advise using two garden forks to cut or push the roots apart, I’ve had good luck by briefly soaking the roots in a pail of water until the majority of the soil is gone. After that, breaking up the clumps is considerably simpler (and you do not damage the plant). Dig up the whole cluster. Check the location of the crown once the earth has been removed. Break it up into larger clumps beginning at the edge (two, three, or no more than four). Reduce the length of the leaves by about a third to a half. Replant. If you want to hasten growth, you can add a fertilizer heavy in phosphorus.
Daylilies thrive in full sun and a location with healthy, well-drained soil, though they will endure in less-than-ideal situations. One inch should be buried beneath the plant’s crown, which is where the leaves and roots converge. Water and mulch a daylily that has just been planted to keep it moist. Daylilies are unaffected by the red lily-leaf insect, which has ravaged Asiatic and Oriental lilies.
There are countless lovely daylilies to pick from. To have daylilies bloom from late spring into fall, combine early, mid-season, late flowering kinds, and repeat bloomers.
Did you know: Despite their name, daylilies are not “real” lilies (from the genus Lilium). If you’re interested in learning how to grow Asiatic and Oriental lilies, visit our Lilies page.
Are daylilies self-propagating?
- Zones 3–9 are considered to be hardy.
- Daylilies can grow in nearly any type of soil, but adding compost can enhance drainage and nutrition and help them bloom more effectively.
- Sunlight: full (6 hours per day).
- Drought-resistant, but flowers better with one inch of water each week.
- Give daylilies plenty of room because they dislike competition and quickly grow to cover enormous regions.
If so, do daylilies self-seed?
Hemerocallis fulva, often known as ditch lilies or tiger lilies, is a common orange daylily that is exceedingly invasive and difficult to eradicate once established. Unlike many other garden favorites, however, these daylilies don’t require any particular maintenance at all to establish themselves. They might spread from a long-established stand or from tubers dumped on the garden floor from nearby gardens. When daylilies grow out of hand, many gardeners worry, but they must be pulled out patiently because they are not common landscaping plants.
Even though orange daylilies are typically the troublesome plants, hybrid daylilies can become out of control by self-seeding, so use caution if you decide to swap out your orange daylilies for these varieties. A lot of future hassles can be avoided by putting up a barrier long before planting season and collecting any seedpods that may sprout on your hybrid daylilies.
Working with daylilies is similar to dealing with a perennial weed because of the way it acts. Your management attempts must take into consideration this behavior since they emerge from soil-based tubers.
Does daylily seed spread?
The gardener has a huge selection of colors and sizes thanks to the more than 60,000 different daylily species (Hemerocallis spp.). There is a daylily that will flourish in each of the U.S. Department of Agriculture plant hardiness zones 2 and above, though the species and cultivar you select may depend on where you reside.
Daylilies are often propagated by root division because their seeds do not germinate and may or may not possess the same traits as the parent plant. To create new types, though, growers use seeds. Daylily seeds germinate within a week to ten days of being planted, assuming you have properly prepared and nurtured them.
How rapidly do daylilies reproduce?
A hardy perennial, daylilies can withstand prolonged neglect and yet add vibrant splashes of color to the landscape. I am aware because I have abused daylilies. It’s simple to forget that they can flourish with some assistance because they thrive in poor soil, severe weather, inadequate light, and bone-dry circumstances. The plants will thrive with only minimal maintenance, and you’ll soon discover that your garden needs more. Given how simple it is to reproduce daylilies, this is hardly a problem.
Daylily plants come in a variety of sizes, from small, feathery clusters to big, fans of green leaves, and the flowers offer a rainbow spectrum of colors that bloom over a lengthy period of time. Because of these variations in color and size, I’ve discovered that sometimes when I plant, I do so with an artistic goal in mind, but as the plants grow, I find myself wanting to move them around and grow more of the ones I particularly enjoy. A blessing in those circumstances is simple propagation.
There are just two main methods for growing daylilies. By seed is first. The flowers dry after flowering and pollination, at which point a tiny, green seed pod forms at the base. The seed pod will develop over the course of a few months, and as it reaches maturity, it will turn brown. Eventually, the brown pods will break open. There will be shiny black seeds inside. These immature seeds should be sown in the fall for natural winter cold or they should be stored in the refrigerator in a plastic bag for approximately a month in order for them to germinate. They are prepared to seed outside in the spring after this cooling off phase.
It’s a gamble to collect and plant daylily seeds in your garden. You are probably growing hybrid daylilies. Because they are a cross between different types, they won’t grow true to the parent plant when produced from seed. You cannot distinguish which flower fertilized another if you have different daylilies in your bed. Pollination from various hybrid parents or hybrid cultivars will produce a seed that will eventually develop into an unidentified plant.
A seed may need three years to sprout and develop into a flowering plant. Be prepared for a surprise when the plant sprouts its first bloom after all that time. There is no way to predict in advance what color or size it will be, but given the wealth of advantages daylilies provide, it will undoubtedly be a pleasant surprise.
Remove the seed pods if you don’t want to save the seeds. Usually, plants that produce seeds the next year have fewer blossoms. There is no justification to purposefully limit future blossoms as one of the main reasons daylilies are grown is for their flowers.
Division is the second method of daylily propagation. When you want your plant to have the same size and color as the parent, dividing large clumps of daylilies is the ideal technique of propagation. In addition, flowers will grow more quickly. Every three to four years, each plant forms a clump that is prepared for division. You’re doing yourself and the plant a favor by routinely dividing because undivided plants will start to produce fewer flowers.
You can divide daylilies in the spring or the fall. After being divided in the spring, plants develop swiftly, although they rarely blossom the first year. I favor propagating in the fall primarily for that reason. Plants propagated in the fall usually always blossom the following season. The best time to divide and transplant the divisions is after the plant has flowered, but at least six weeks before the ground freezes.
Start by completely digging up the plant. Push your spade as far as you can in a circle around the plant, starting approximately six to eight inches away. With the spade, lift the plant while attempting to preserve the rootball. While it shouldn’t be too difficult, larger plants might have roots that extend beyond the hole and could potentially be torn as a result.
To reveal the roots, brush or wash away the soil that is covering them. The roots of many daylilies are swollen and tuberous. The plant stores its food and water here, allowing the divisions to thrive after transplanting. The transplant has a better likelihood of success the more roots there are in the division.
You can see how the fans come together at the roots to produce different and unique parts. These sections can be separated from one another. It is simplest for me to start by lightly shaking the plant and observing where it naturally starts to split. I next carefully divide the plant into two parts. Each of those divisions can frequently be further broken down into two or three other divisions.
When pulling gently, bigger plants and clusters might not separate. It could be necessary to split the clump by inserting two garden forks back to back in the center of it. Garden forks lessen root damage compared to using two spades, which causes greater harm. The divisions can typically be further separated by hand once they are smaller.
Divisions ought to have three or four sturdy roots attached fans. These will take root more quickly, form sturdy clumps, and bloom after a year. You can even cut it into smaller pieces so that each fan has just five or six thin leaves. These individual fans can be moved without issue, but it might take them a few seasons to get big enough to start blooming.
There are some enormous, mature clumps that may have roots that are so thick in the middle that they resemble a solid mass. It might be necessary to use a sharp shovel or garden knife to split these clumps apart. Try to cut so that the identity of the individual fans is preserved.
To prevent the roots from drying up, the divisions should be transferred as soon as they are dug up. Cut the leaves on each division so that just five to six inches are left above the crown. This lessens stress and water loss. The area at the junction of the leaves and roots is known as the crown and is often cream in color. Put the plant in the hole with the crown a little more than an inch beneath the surface.
Daylilies thrive in broad sunlight and moist, organically-rich soil. If you can add organic stuff to the transplant area in advance, do so. A high phosphorus fertilizer addition will aid in promoting root growth. The dirt in the hole for each plant should at the very least have a handful of compost and fertilizer added to it if you’re transplanting divisions amid other, established plants, as I frequently do. Fill the hole and compact the earth around the roots.
Water the area well after the divisions have been planted. Till the ground freezes, keep the soil moist. To control the soil’s temperature and moisture content, add a few inches of mulch. Mulch also helps the plants look more attractive and lessens weed growth.
For some daylily varieties, there is a third way of propagation available. Some daylilies’ stems, or scapes, may support tiny plants. If kept on the plant for a long enough period of time, this tiny plant will develop leaves, a crown, and even roots. Proliferations are the name given to these little clones of the original daylily. Proliferations can either be transplanted or potted up. Both above and below the proliferation, cut the scape. The crown can be dipped in rooting hormone to aid start the growth of roots if they haven’t already started. Since none of the daylily kinds I cultivate produce proliferations, I am unable to speak from personal experience with this approach.
Daylilies eventually grow into thick mats of vegetation. You can keep the plants under control and looking their best by dividing them. A excellent approach to spread their wonder to new locations is through reproduction. Remember that many of your friends who garden might be interested in some of your excess divisions.
Should daylilies be deadheaded?
Deadheading, or removing the old flowers from the daylily, is not required. It does, however, offer certain advantages in terms of supporting the upkeep of a robust and healthy garden. For many neat gardeners, removing spent daylily blossoms is crucial since they could give the flower bed an untidy appearance.
What should you do with daylily seed pods?
the gathering of daylily seeds Allow the seed pod to dry naturally on the stalk if the blossom turns into a seed pod. Pick it when it begins to turn brown and crack open, and keep it in a warm, dry area until you’re ready to plant. The seed might be planted right away.
Can daylily seeds be saved?
It can be exciting to save and store daylily seeds from your favorite daylily cross, but seeing the flower buds gradually emerge is even more satisfying. You can grow an entirely new variety of daylily by storing the seeds. By manually pollinating the desired daylily blossoms and crossing two flowers, you can create your own seed strains. The long single pistol has the stigma at the very end. It protrudes from the daylily flower’s throat and rests amidst the stamen cluster. If the crossings are successful, the pollen only needs 30 minutes to travel along the pollen tube and begin developing a seedpod. But for this to work, the appropriate daylily varieties must have been crossed. Once you’ve combined the appropriate flowers, you can use a little drawstring nylon mesh bag to cover the flower where you’ve applied the pollen to the stigma. This accomplishes two goals.
- to prevent other pollinators, such as bees and insects, from visiting the newly hybridized flowers.
- You won’t lose any seeds if you neglect to collect them.
From pollination to seed preservation, it only takes 6 to 8 weeks. Tetraploid daylilies must wait 6 weeks, whereas diploid daylilies must wait 8 weeks. It’s crucial to harvest and collect daylily seeds at the proper time. Daylily seed collection that is done too early can be disastrous.
Removing daylily seeds is a necessary part of daylily maintenance. When the seed pods are mature, ripe, and plump, this is done. At this point, the seed pod has turned brown and the seed case is beginning to separate. Only when the seeds are completely black and not cream or brown can you tell that the daylily seeds are ripe. At this time, you can begin collecting daylily seeds for storage and upcoming planting.
Only do this on a bright, sunny day after it hasn’t rained, and when the seedpod first begins to break open. Before the birds devour the seeds, carefully remove and store the black seeds. Depending on the size of the seed pod and the size of the bloom, the three-part seed capsule typically contains 1 to 20 seeds.
The seeds should not be kept in plastic bags because doing so would cause them to sweat and rot.
Before storing your seeds, make sure they are totally dry. To properly dry the seeds, you might need to spread them out on newspaper, brown paper, or paper towels for up to a week. Otherwise, simply place the seeds into their envelopes and prepare them for storage. If necessary, leave the envelopes open to allow the seeds to properly air dry and label the seed packages accordingly. The seed bundles should then be sealed for storage.
The ideal place to keep daylily seeds for future planting is in the crisper at cool temps in the refrigerator. This will keep the seeds fresh but prevent them from freezing.
