How to Grow Rose of Sharon Plants



Immortality: The Rose of Sharon

One of my most challenging and rewarding landscaping experiences was an attempt to grow Rose of Sharon plants. I succeeded, much to my own amazement. I also recall photographing an ant sipping rainwater from the heart of one beautiful flowers, on my Rose of Sharon shrub, shortly after a summer shower.

The Rose of Sharon (Hibiscus syriacus) is a vase shaped plant, from the genus Hibiscus and the plant family Malvaceae. (1)

The flowering shrub grows to approximately two to four meters in height, with flowers that may be white, pink, red, lavender or purple. They are edible and are excellent as cut flowers, because they last for a long time.

Some of the more common cultivars or cuttings that have been grown into shrubs are called Diana, Lady Stanley, Ardens, Lucy and Blushing Bride. (2)

The Hibiscus syriacus is also known as the Rose of Althea. (3)

In South Korea, the Hibiscus syriacus is their national flower. The Korean word "mugung" means "immorality" (4)

It has been considered a heavenly flower. It was initially adopted as the national flower after their liberation from Japan. (5)

Because of the many blossoms, it represents the Koreans "wish for long lasting national development and prosperity" (6)

It also depicts "the glories of the county with its trials and tribulations". (7)

In my own personal experience, I learned that the Rose of Sharon, more commonly called the hibiscus, will grow where it is very hot in the summer. It was hot, where I was living in southern Ontario.

I purchased my first Rose of Sharon shrub called "Diana", from a local garden center. It had been pruned to grow like a tree, with several small branches. It was about three feet tall, at the time and had a single white flower. (Note that the shrubs can be multi-stemmed, as they tend to grow small plants beside the main root.) The leaves were a healthy, light green color. (When it is hot, they tend to burn and may become brownish colored.)

I learned that the hibiscus could be started from cuttings, so whenever I had a cut flower that finished blossoming, I would leave it in the vase and let it root in the water. Once rooted, I would plant it in its own clay flowerpot. Over time, I gave a number of Rose of Sharon plants away, but could have planted them as a hedge.

I found out that the Rose of Sharon grows well in full sunlight. My shrub was planted in a relatively sheltered, landscaped area on a gentle slope, by the driveway, on the east side of the house. Initially, I planted it deep and surrounded it with compost and peat moss to retain its moisture. Then, I planted several small junipers around the shrub and built a rock pathway, through the area.

The place it was planted appeared to be difficult to landscape, as the soil seemed too dry and sandy to grow anything. To my amazement, this proved to be an excellent location for it. (The soil does need to be well drained to prevent fungal infections.)

It was not long before the first blossom came out and it was gorgeous to behold. Before long, the shrub was covered with blossoms that seemed to last forever.

I began to fertilize the Rose of Sharon, approximately every four to six weeks and watered it regularly, but not necessarily every day. It seemed to thrive. I soon found out that the stamen of the flowers produces pollen that attracts bees.

The Rose of Sharon, being a deciduous plant, normally sheds its leaves, at the end of the summer. I worried about whether it would survive the southern Ontario winter, as the temperature can be below freezing, for months at a time, so I mulched the shrub with leaves that had fallen from the maple trees, in the yard.

Much to my surprise, when spring came, the leaves on the Rose of Sharon began to sprout and it was not long before it had flowers, again. Year after year, I had a lot of enjoyment from my Rose of Sharon shrub, as it blossomed profusely.

If asked how to grow Rose of Sharon plants, I would highly recommend it to anyone as a flowering shrub and suggest that they follow these guidelines.
