Facts About Rose of Sharon

Origin

The rose of Sharon, or Hibiscus syriacus, is a shrub or small tree that belongs in the hibiscus or mallow family called Malvaceae. This flowering shrub is native to eastern Asia, specifically to the south-central and southeastern part of China. It then became popular in most parts of Asia, even in the United Kingdom and the USA.

The rose of Sharon has many other names. Its common name is shrub althea, but in other locations, it has different names. In the United Kingdom, it’s called rose mallow; in China, it is Chinese hibiscus; and in Korea, it is called Korean rose.

In South Korea, the rose of Sharon serves as their national flower. It appears in various state emblems and is even mentioned in their national anthem since the flower has a poetic comparison to the country.

Aside from cultural aspects, the rose of Sharon also has Biblical references. Most Bible scholars believe that this flower is the one mentioned in the Songs of Solomon and symbolizes Jesus Christ.

Growing Conditions

Most growers agree that taking care of the rose of Sharon is easy, but it depends on your experience.

The rose of Sharon is a hardy deciduous shrub. It means that it sheds foliage every time its growing season ends. During that time, make sure to prune some parts of it to maintain its shape, especially if you are into landscaping.

As mentioned, the rose of Sharon is native to eastern Asia, but it can also adapt and grow in most USDA plant hardiness areas. It thrives best on moist but well-drained soil in full sun exposure or partly shaded areas. It can also tolerate air pollution, drought, heat, humidity, and any types of soil condition except extremely dry and soggy soils.

Even if it can survive some common plant conditions, it can’t resist common pest problems. Its major pest problem is the infestation of Japanese beetles, though it can easily be controlled since Japanese beetles are more visible than other insects.

If you spot one, you can simply pick them by hand and drop them in a container with soapy water. Since this insect breathes on its skin, the soapy water will coat its body and suffocate it until it dies.

Most species of rose of Sharon grow in suburban areas and can naturally scatter its seeds. If you are following a landscape display, make sure to watch where its seeds spread to avoid it from growing in unwanted areas.

Also, to make sure you grow the best blooms, try adding organic compost or mulch to keep it healthy as it matures.

Plant Description

Plant Height

An average height of a rose of Sharon shrub is about 2 to 4 meters or 7 to 12 feet. It stands upright and bears large trumpet-shaped flowers. Its stems and branches can grow longer and straighter from its usual size of 1.5 to 4 centimeters or 0.5 to 1.5 inches above the ground if you maintain pruning.

Leaves

The leaves of the rose of Sharon have three distinct lobes and toothed margins. It grows during the late season or growing stage, or during May. Its colors are green or yellowish-green. It alternately appears on the branches and measures 7.5 centimeters or 3 inches long.

Flowers

Rose of Sharon's flowers have a pistil and a stamen at the center, just like any other hibiscus flower, and are surrounded by 5 petals. They normally measures about 7.5 centimeters or 3 inches in diameter, and come in colors of white, purple, pink, red, and blue, while some cultivars have bicolor.

The flowers will start to bloom from July through September. Throughout the summer, the flowers can grow up to 10 centimeters or 4 inches wide. This makes it one of the most blooming plants during the summer season compared to other flowering plants.

A matured stem of a rose of Sharon is flexible enough to carry the weight of its large blooms. But after the flowering season, it will start to bend over.

Fruit Shape, Size, and Color

Though most varieties produce fruits, some modern cultivars are fruitless. Typically, the fruit of the rose of Sharon is ornamentally attractive and appear in 5-valved dehiscent capsules in colors of green or brown.

The fruit persists throughout the winter season, and starts to shatter during the dormant season. Then it will easily spread its germinating seeds around the parent plant’s base and form colonies in time.

Those reniform seeds measure 2 to 4 millimeters long with a row of long and yellowish-white hair on the dorsal line.

How to Grow Rose of Sharon

Soil

Though a rose of Sharon can tolerate any soil type like clay, loam, and sand, it will thrive better when planted in rich soil. The average soil pH it needs is from 5.5 to 7.5.

Light

Being a summer flowering plant, it loves the sun so much. Be sure to place your shrub under the full sun for better growth. To avoid fungal damage, especially to old bushes, don't place it on shaded areas since it can increase the moisture level, allowing fungi and pests to grow.

Temperature & Humidity

Rose of Sharon is a heat lover. It can survive in hot climates, and won't easily die because of dryness. It can also tolerate different humidity conditions, which makes it easier to take care of.

Watering

Most varieties of rose of Sharon are drought-tolerant, especially if it is already mature. So you don’t need to worry about watering them daily, especially during the rainy season.

The leaves and flowers won’t easily dry even if it only receives a little amount of water. Its leaves may be more prone to dry and fall from overwatering.

Fertilizing

Adding fertilizer to maintain your shrub’s growth and health is recommended. But for established ones, you may not consider it.

For newly-grown shrubs, you may use slow-release fertilizers and allow your plant to feed it during late winter or early spring. You can continue using fertilizers for up to four months until the plant fully matures.

If you prefer organic growth, you can put compost into the soil instead and place it near the plant's roots. Don’t forget to water it afterward.

Transplanting

Transplanting is one of the methods you need to do to help your rose of Sharon grow well. Before transplanting, check the location if it has good drainage and full sun to partial shade exposure. Make sure that this spot is your preferred permanent location. Once the location is set, you can now start removing the plant from its container and transfer it to its new location.

Pruning

In reality, the rose of Sharon does not need pruning aside from removing occasionally damaged or dead branches. But if you are into landscaping and would like to maintain a specific shape, you must plan the pruning schedule as early as spring to make time for growth.

The rose of Sharon blooms on the newly-grown branch during the current season, so don't worry if you think you might have removed the flower buds during the early pruning as it won’t affect them.

To propagate by stem cutting, here's a simple guide you can follow:

2. Then, you need to dip the end of the stem using rooting hormone. After that, you can plant the bottom half of each stem.

3. In each pot, place a piece of clear plastic over the top. Then water it well.

4. After watering, place the pots in a shaded area to receive indirect lighting. Check often if the potting mixture stays moist. If needed, you can try to add more water, but avoid getting the soil soggy. After seven days, you can remove the plastic.

5. Within one to two months, check the cuttings by pulling the stems gently to know if it has rooted. If it has, then you should see new leaves form on the stems.

6. Wait for it to grow larger, a growth of 2 inches is enough before you can plant them in your garden.
