Hibiscus syriacus 'Red Heart' | Rose of Sharon

The Hibiscus syriacus 'Red Heart', commonly known as the rose of Sharon, is a captivating flowering shrub that adds a touch of elegance to any garden. Renowned for its stunning blooms and upright growth habit, this cultivar is a favorite among gardeners who wish to bring a vibrant splash of color to their outdoor spaces.

The Rose of Sharon is a deciduous shrub, which means that it loses its leaves in the winter. However, this is more than made up for by the beautiful flowers that it produces in the summer and autumn.

Key Features

Key features of the Hibiscus syriacus 'Red Heart' include:

The shrub's blossoms are a striking combination of red and white, with a bold red center that stands out against the white petals.
Flowering from July to September, it provides a long-lasting display of color when many other plants have faded.
It reaches an ultimate height of approximately 2 meters, making it suitable for a variety of garden sizes and uses, whether as a border, in group plantings, or as a solitary focal point.
The Rose of Sharon is fruit-bearing, which can add interest to the garden even after the flowering period has ended.
It has an upright growth form, which ensures that it takes up less horizontal space in the garden.
The plant is not particular about soil type, as long as it is well-drained, and it can thrive in both sun and partial shade.

Tips

While the Hibiscus syriacus 'Red Heart' doesn't require much pruning, it can be pruned lightly after blooming to maintain shape and encourage more prolific future blooms.
Ensure that the Rose of Sharon receives average water needs, especially in periods of drought, to keep it healthy and stress-free.
Plant your Hibiscus in a location that receives ample sunshine to promote the best flowering, though it will also tolerate partial shade.
For propagation, take semi-ripe cuttings in the late summer. These can be rooted in a potting medium to grow new plants.

Ideal placement of a Hibiscus syriacus 'Red Heart'

For optimal growth and blooming, this variety thrives in locations that receive full sun to partial shade. Its adaptability allows it to prosper in a range of soil types, provided they are well-drained. To truly showcase its vibrant summer and autumn blossoms, situate the shrub where it will receive ample sunlight for the majority of the day. This exposure encourages the most prolific flowering. Partial shade is tolerable, but may result in a reduced number of flowers. Regular watering is necessary to maintain its average water needs, especially in well-draining soils where moisture is not retained for extended periods.

How do I plant a Hibiscus syriacus 'Red Heart'?

To ensure successful cultivation, this shrub requires a well-drained soil, which can range from clay to sandy loam. It thrives in locations that offer full sun to partial shade, allowing it to produce its signature red and white blooms from July through September. When planting, provide ample space for the shrub to reach its mature height of 2 meters with an upright growth habit. Watering should be consistent, especially during dry spells, to maintain its lush green foliage throughout the growing seasons. Planting in pot allows for flexibility in placement within the landscape.

Pruning a Hibiscus syriacus 'Red Heart'

Hibiscus syriacus 'Red Heart' is a low-maintenance shrub that thrives with minimal intervention. While it doesn't demand regular pruning, occasional shaping can encourage a more robust bloom and maintain its upright growth habit. If shaping is desired, it's best to prune in late winter or early spring before new growth begins. Pruning at this time allows gardeners to remove any dead or damaged wood and to shape the plant without disrupting its flowering, as it blooms on new wood. Always use clean, sharp tools to make precise cuts.

Watering a Hibiscus syriacus 'Red Heart'

Hibiscus syriacus 'Red Heart' thrives with consistent moisture, particularly during its flowering period from July through September. It's critical to ensure the soil remains well-drained to avoid waterlogging, which could be detrimental to the plant's health. Provide a deep watering to encourage a strong root system, allowing the soil to dry out slightly between waterings. During hot and dry spells, an increase in watering frequency may be necessary to keep the shrub hydrated, but always be cautious not to overwater. Adequate hydration will support the shrub's production of the striking red and white blooms it's known for.

Fertilising a Hibiscus syriacus 'Red Heart'

To ensure the Hibiscus syriacus 'Red Heart' displays its full flowering potential, adequate fertilization is essential. This species thrives with a balanced, slow-release fertilizer applied in early spring as new growth appears. A second application can be beneficial during the mid-summer to support the prolonged flowering season that stretches from July through September.

The fertilizer should be rich in essential nutrients to promote healthy foliage and vibrant blooms. Apply according to the manufacturer's instructions, avoiding over-fertilization which can lead to excessive leaf growth at the expense of flowers. Water the shrub well after applying fertilizer to help distribute the nutrients into the soil. Regular fertilization, along with consistent watering and well-drained soil conditions, will contribute to the overall health and aesthetic appeal of this striking shrub.
