Make a bold statement with the captivating Hibiscus 'Red Heart' Mini Standard, a professionally trained topiary that combines pure white petals with a dramatic deep red centre for an unforgettable display. This striking specimen features a variable stem height of 60-80cm crowned with a perfectly rounded head, offering both design flexibility and spectacular visual impact that commands attention in any garden setting.
The 'Red Heart' variety produces absolutely stunning bicoloured flowers that create one of the most eye-catching displays in the hibiscus family. Each magnificent bloom measures 12-15cm across, featuring pristine white petals that provide a striking contrast to the deep crimson-red centre that gives this variety its distinctive name. The dramatic colour combination is enhanced by prominent burgundy stamens, whilst the petals often display subtle pink veining that intensifies the overall effect. Fresh blooms appear continuously throughout the season, each lasting 1-2 days before being replaced by new buds.
Dense, glossy green foliage provides the perfect backdrop to showcase the spectacular bicoloured blooms. The professionally trained standard form creates an elegant architectural element with clean lines and formal appeal. The variable stem height of 60-80cm offers excellent design flexibility, allowing gardeners to select specimens that perfectly suit their specific garden requirements whilst maintaining the sophisticated impact of a formal topiary.
Demands full sun exposure of at least 6-8 hours daily to develop the intense red colouration in the flower centres and maintain vigorous flowering. Choose a warm, sheltered location with protection from strong winds, which can damage the large, delicate blooms and compromise the carefully maintained topiary structure. The striking flower colours are most vibrant in bright sunlight.
Thrives in well-draining, fertile soil with a pH between 6.0-7.0. For container cultivation, use a premium multipurpose compost enhanced with perlite or horticultural grit to ensure excellent drainage. Heavy, poorly draining soils should be avoided as they can lead to root rot and significantly reduce the plant's flowering capacity.
Maintain consistent soil moisture during the active growing period, watering thoroughly when the top 3cm of soil becomes dry. Container specimens require more frequent attention, especially during hot summer weather when the large blooms need adequate moisture to maintain their crisp appearance and vibrant colours. Reduce watering frequency during winter dormancy.
Apply a balanced liquid fertiliser every two weeks throughout the growing season (April-September). Switch to a high-potash fertiliser during summer months to promote prolific flowering and intensify the dramatic red centre colouration. Container plants benefit from slow-release fertiliser granules applied in spring, supplemented with regular liquid feeding during peak growth periods.
Pruning
Conduct light pruning in late winter or early spring to maintain the topiary's perfect shape and encourage dense, bushy growth in the crown. Remove any shoots that emerge on the clear stem immediately to preserve the standard form. Regular deadheading of spent blooms is essential to maintain the plant's appearance and promote continuous flowering throughout the season.
Winter Protection
Essential winter protection is required in most UK locations due to the plant's tender nature. Move container plants to a frost-free greenhouse, conservatory, or bright indoor location when temperatures drop below 5°C. Garden-planted specimens need substantial fleece protection or should be lifted and overwintered in a cool, bright indoor space.
Pest and Disease Management
Generally robust but may occasionally attract aphids, whitefly, or spider mites, particularly when grown under protection. The contrasting flower colours can make pest damage more noticeable, so regular inspection is important. Ensure good air circulation around the plant and avoid watering the foliage to minimise fungal problems.
The striking bicoloured blooms work beautifully in both contrasting and complementary colour schemes. Pairs exceptionally well with deep red flowers like salvias or dahlias for dramatic monochromatic displays, or with silver-leafed plants such as artemisia and lavender for sophisticated contrasts. White flowering companions enhance the white petals, whilst the variable stem height allows for creative layering with plants of different heights.
The 60-80cm stem height range provides valuable design versatility, enabling you to select specimens that perfectly match your garden's requirements. Shorter stems (60cm) work excellently in intimate garden spaces or lower mixed borders, whilst taller specimens (80cm) create more commanding focal points and are ideal for larger garden areas or formal parterre-style plantings.
Your Hibiscus 'Red Heart' arrives as a mature, well-established plant in a nursery container, professionally trained with a clear stem within the 60-80cm range and a well-developed crown. The plant is ready for immediate garden planting or can continue thriving in containers throughout the growing season.
Position your 'Red Heart' where the spectacular bicoloured blooms can be fully appreciated, ideally where they'll receive morning sunlight to intensify the red centre colouration. The dramatic flowers create stunning photographic opportunities and are particularly striking when planted where they can be viewed against a dark background such as evergreen hedging. With proper care and winter protection, this remarkable standard will provide many seasons of breathtaking beauty, creating an unforgettable focal point that guests will remember long after visiting your garden.
Buying Shrubs from Jacksons Nurseries
At Jacksons Nurseries we sell a variety of shrubs both evergreen and deciduous with a variety of flowering times throughout the year. At certain times of the year our shrubs you buy from us may not look like the images shown on our website when deciduous leaves have fallen, the shrub has finished flowering or has been trimmed back.
Some leaves on evergreen shrubs can be damaged in winter by frost or harsh winds but in spring new leaves will readily replace those damaged. This is quite normal on many evergreen varieties and is preferable to plants grown with excessive protection that show cold shock once planted out and establish less satisfactory initially.
Availability: Stock availability figures are provided as a guide only. There is a delay between orders being placed and the plants being gathered by our pulling team. During this time it may be possible for a member of the public to purchase these plants from our Garden Centre, while this is rare it is a possibility and we will notify you of any problems as soon as possible. This figure may also include plants that have not yet be flagged as unsaleable.

Orders containing Pre-ordered products will be shipped as a single order when all items become available. Large orders may be part shipped, please contact us on 01782 502741 or email sales@jacksonsnurseries.co.uk.
* Please Note: Shrubs in 20 litre pots and above might require a pallet delivery starting at £79.99 per pallet. Depending on the exact pot size and height it may be possible to get approximately 5 plants per pallet at no extra cost. The maximum height we can dispatch on a pallet is 2.0m, this includes the height of the pallet and pot.
Shrubs are deciduous or evergreen woody plants, and often provide fragrant flowers, berries and foliage. They are good for structural framework, and they can provide a wonderful shelter and food source for wildlife.
Planting and Conditions
Container grown shrubs can be grown at any time of year. It is a little known fact that shrubs planted in the autumn and winter will be easier to look after than those planted in the spring and summer, because they will have time to establish and become hardy in the cooler months.
Plant the shrub at the same depth as it was in its original pot. Planting too deeply can result in root and stem rot.
One of the biggest causes of death in new shrubs is drought stress, so keep it well watered until it’s established.
Make sure you loosen the soil prior to planting. Most shrubs are tolerant of most soil types as long as it is fairly well draining.
Most shrubs will grow happily in containers, but they will be much more demanding on feeding and watering than shrubs in the ground would be. They will also need potting on every couple of years so that they don’t suffocate or become stunted in their pot.
Aftercare and Pruning
Once established, shrubs generally do not require much water. However, at first they need careful, frequent watering and should not be left to dry out.
Shrubs in the ground are generally not demanding and in most cases, annual feeding with general purpose fertilizer will suffice. Shrubs in containers may need more feeding; usually from early spring until late summer.
Shrubs also benefit from mulching in order to supress weeds, conserve moisture and provide vital nutrients. Mulch also greatly improves soil conditions. Shrubs can be mulched in late winter, after fertiliser has been applied, but it can be mulched through autumn to late spring as long as the ground is damp.
All shrubs benefit from dead-heading once spent flowers become apparent. Rhododendrons and Lilac especially benefit from the removal of dead flowers.
Some shrubs may show signs of reverted growth or ‘sporting’. This is where random shoots of different leaves associated with the plant’s parentage begin to appear. Most commonly this is where plants with variegated leaves sprout pure green growths instead of variegated ones.
To control reversion, remove reverted shoots promptly to discourage them. Reverted shoots are usually much more vigorous than the variegated ones, and thus should be completely pruned out and cut back into wood containing variegated foliage.
Potential Issues
Although shrubs are usually very robust garden plants, they can sometimes start to decline with no apparent or obvious reason.
This will start with browning leaves, which could indicate plant stress due to lack of water or waterlogging, an establishment failure or, in the worst case scenario, honey fungus. Another cause of leaf browning is a high salt content in the soil. This could be a natural occurrence, especially if you live near the ocean, or it could be from over fertilisation.
To remedy a high salt content, cut back on fertiliser and step up your watering regime for the next few weeks. If you live by the ocean, this will be harder to remedy—but stepping up your watering will help to wash some of the salt away all the same.
