Seed Swaps



Daylily is a member of the Hemerocallis family. Its botanical name is Hemerocallis.

Daylily foliage varies in size and fineness: tiny varieties can look like a clump of grass with wide blades at first glance. Larger varieties with bigger leaves can be 3 to 4 inches wide and waist-high on an adult.

The flower stalks, called scapes, should hold the flowers above or at the top of the leaves. Newer hybrids often have extended and repeat blooming times; some have branching scapes or simply put up more scapes as the season progresses. Each mature fan of a daylily should put up a scape: the leaves join together at the base in a kind of fan shape.

Flowers can be trumpet shaped to star-shaped, rounded, recurved, unusual form, or spider, where the length of the petals is a certain proportion more than their width. Flower size is not always related to the size of the leaves, though typically fine plants with short, thin leaves have smaller flower sizes. The basic form has six petals (three sepals and three tepals), but there are forms called doubles that have more.

Colors vary from purple to red to orange to yellow to almost perfectly white, often with a green, yellow, or orange throat. Many color patterns are available, including bitones, eyezones, and edges. Some have ruffled edges or even a slight glittering referred to as diamond dusting.

Bloom times vary: some will bloom early in the season, some will not bloom until later in the season, even among the rebloomers.

Blooms normally display as a colour very similar to   Chrome yellow and   Brick red. When mature, they grow to 20.3 cm (7.92 inches imperial) in diameter.

It is an edible flower / ornamental and is treated mainly as a perennial, so it grows best over a period of time (3 years and greater).

Daylily is known for growing with a clump-forming habit to a height of approximately 1.00 metres (that's 3.25 feet in imperial). This plant tends to bloom in early summer.

If you would like to attract butterflies, bees and birds to your garden, consider growing this plant.

Popular varieties of Daylily include: Stella De Oro, Tiger Lily, Pardon Me, Strawberry Candy and Happy Returns.

China is thought to be the country of origin for Daylily.

Daylily is normally quite a low maintenance plant and is normally very easy to grow - great for beginner gardeners!

How to grow Daylily

  • Full Sun

  • Low

Hemerocallis fulva is the wild strain with orange flowers. It is exceptionally suited to naturalizing in open spaces.

Dig individual holes several inches wider than the root system and at least 12 inches deep. The soil should be worked into a friable condition before replacing it around the roots. Construct a cone-like mound of soil in the bottom middle of the planting hole. Set the plant with roots spread over the top of the mound and trailing downward. Adjust the height of the mound so the plant sits as deep as it grew originally.

Daylilies grow better when fertilized. They respond to a fertilizer analysis containing a moderate amount of nitrogen and high rates of phosphorous and potash. Analyses such as 5-10-15 and 6-12-12 supply such requirements. The first application is applied in the early spring just as new growth commences. A rate of 2 pounds per 100 square feet of area is suggested. A second application during the growing season is recommended; however, there is no research to substantiate the exact timing of the second application. Most daylily growers make a second application of fertilizer during midsummer using the 2 pound rate per 100 square feet.

Position in a full sun location and remember to apply water fairly sparingly. As a rough idea of the types of climates Daylily does best in, check to see if your local area is within USDA Hardiness Zones 3 and 9. Daylily needs a soil ph of 6.0 to 7.0 (weakly acidic soil - neutral soil). Daylily is generally regarded as a hardy plant, so this plant will grow or become dormant during the winter.

Growing Daylily from seed

There seems to be much improved germination of sprouting daylily seeds when they are soaked in a 1 ounce solution of house-hold hydrogen peroxide mixed into 2 liters of water. Keep seeds and soaking solution out of reach of children and pets. Never allow sprouting seeds to dry out. That is a sure-fire way to bring germination percentages down to zero! This is one of the problems of using small compartment seed sprouting trays.

Leave the seeds in the solution until they just start to sprout. That may take a while for some seeds. A small white rootlet will begin forming at the end of the seed. When one or two seeds show this white rootlet, plant all the soaking seeds in that container. Don’t wait for all the seeds of a given cross to sprout before planting. If left soaking too long, the rootlets will turn to mush. Some are seeds are slower to sprout than others. After a week, or ten days, it is best to plant the seeds whether or not they have begin to sprout and hope for the best. Soft seeds can be rejected as they will not sprout and take up planting room.

Sow early to mid spring in pots or modules of peat free compost or fine propagating bark. Cover with pearlite or vermiculite and place in a cold frame. Germination takes three to four weeks

Daylilies hybridize easily and to get more of the same plant, divide a mature plant rather than planting seed.

Look to ensure a distance 11.7 inches (30.0 cm) between Daylily seeds when sowing to make sure your seedlings have enough space.

By our calculations*, you should look at sowing Daylily about 42 days before your last frost date .

Transplanting Daylily

Transplants may not bloom well the first year.
Prefers full sun to light shade. Blooms in full sun may exhibit a tendency to fade. If this happens, move the plants to a spot that receives some afternoon shade.
Propagate by division when well established (about 5 years) in early spring, summer after flowers fade or mid-fall.

Daylily is hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside.

Harvesting Daylily

2 Both the young spring foliage and the flower buds may be added to soups or salads or eaten as a vegetable.

Many Hemerocallis species are edible. The entire plant is edible and tasty. Fairly high in protein and vitamin C. Leaves and shoots are consumed young before they become fibrous. Flowers are eaten raw or cooked before or after they open. Root eaten raw or cooked.

This plant is toxic to pets. 3

Seed Saving Daylily

Daylilies are very easy to gather seeds from. Allow the flowers to fade and drop naturally. If the flower was fertilized a green seed pod will develop where the flower was attached to the stem. Not all daylilies will be fertile and so some plants may never produce seeds, nor will all flowers of fertile daylilies produce seeds. Some varieties will produce more seed pods than others.
Allow the green pod to grow to maturity; it will turn brown and when the seeds are ripe, the pod will open at the end. You can collect the pod and lay it on a plate to dry for a few days.
To remove the seeds split the pod open along its seams and gently nudge the seeds out. The seeds are roundish and a shiny black. Depending upon the variety seed size can be between an 1/8 and 1/4 inch wide. Daylily seeds are thick and should dry for a few more days before being packed. 4

Daylily Etymology

The flowers of the genus hemerocallis are open for but one day. Hence, the name daylily. Newer hybrids may have extended and repeat blooming times.

Daylily Folklore & Trivia

The first written record about the daylily is about 2697 B.C. when Emperor Huan Ti arranged for a Materia Medica to be written for him by Chi Pai. Daylilies were used as food at that time. They were thought to benefit the mind and strengthen willpower. The plants grew wild in the woods and were moved to the garden for use at the table.
