Hydrangea paniculata SUNDAE FRAISE® ‘Rensun’

Sundae Fraise® is another new hhydrangea clone from Jean Renault from France. It was derived from the already successful variety Vanille Fraise®, but this one is smaller and more compact. The flowers are medium sized panicles that open creamy white in late July and soon gain light pink shades that get deeper and richer with time. By the end of summer the whole shrub is covered with strawberry coating all over. The flowers can be cut at any time and dried (upside down) for further use in winter decorations.
Deciduous leaves are ovate to oval, pointed, deep green. Stems are strong, deep burgundy red. We recommend regular pruning every spring before the buds begin to swell. By cutting at least two thirds of previous year’s growth you will get a strong shrub with larger flowers and a regular framework shape. Sundae Fraise® hydrangea makes a dense and compact bush covered with flowers from August till September, possibly October.
In 2010 it was awarded silver medal at the international fair Plantarium in Boskoop, the Netherlands, where new varieties are introduced to nurseries and gardening public. It is patented and protected by PBR in Europe under 20101147. Unauthorized propagation without licence is prohibited.
It will grow in almost any soil type, preferably humus-rich, moist soil that will not too heavy or shallow. Once established it does not extra watering like big-leaf hydrangeas. Full sun is best but it will grow in shade, too. Feeding is much recommended to enhance flower size. Experienced hardiness is -29°C (USDA zone 5) but is supposed to take much stronger frost.

About this section

Our plants are under greater threat than ever before. There is increasing movement of plants and other material traded from an increasing variety of sources. This increases the chances of exotic pests arriving with imported goods and travellers, as well as by natural means. Shoot is working with Defra to help members to do their part in preventing the introduction and spread of invasive risks.

Hydrangea Paniculata Sundae Fraise

Hydrangea paniculata Sundae Fraise is a new variety, prized for its very floriferous habit and showy, colour changing blossoms. Compact, low-growing and highly-decorative, this cultivar is a perfect candidate for a focal point in the garden or, planted en masse, as a stunning flowering border.

Growing in a bushy habit, Hydrangea Sundae Fraise has medium green, oval, broad leaves borne on crimson red stems. In July, this deciduous shrub is engulfed in a profusion of cone-like, upright panicles. The blossoms open as creamy white, soon to be tinged with pink, and, finally, turning a lovely strawberry pink from August to the end of the flowering season. As it is the case with all Hydrangeas, the intensity and shade of the blossoms will depend on the pH of the soil it is planted in.

Hydrangea Sundae Fraise is easy to grow and to care for. This cultivar will thrive in humus-rich, moist soils, regardless of their type. Although this deciduous shrub tolerates partial shade, for best results and more vibrant colours of the flowers, choose a spot in full sun. Quite robust once established, this particular variety does not require as much watering as other Hydrangea varieties.

Even though its delicate, showy looks suggest otherwise, Hydrangea paniculata Sundae Fraise is a tough cultivar. It can survive even if the temperatures drop to 20 degrees below zero, and it is fully hardy in the United Kingdom. Not only that this flowering shrub is not bothered by frost, it can also flourish in both sheltered and exposed location, regardless of the cold winter winds.

Bred to keep its compact size as it matures, Hydrangea Sundae Fraise will grow to be up to 120 centimetres high and across. This makes it ideally suited for small gardens and growing in large containers. When it comes to maintenance, a little effort goes a long way with Hydrangeas. Pruning should be done early in the spring, removing the previous season’s flowering shoots to encourage prolific flowering. After pruning, mulch and feed for the plant to produce larger blossoms.

Attractive habit and a stunning display of blossoms make Hydrangea Sundae Fraise a marvelous specimen plant, whether in a garden or a container. Use this floriferous perennial to add a profusion of colour to your patio, balcony or a mixed shrub border.

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.

Hydrangea paniculata Sundae Fraise

All hydrangeas like moist but well drained soil and full sun or partial shade. They can get very large if left unpruned and are best off planted in the ground where their roots can stay cool and reach out for water and nutrients.

Dig a hole at least twice as wide and half as deep again as the pot it is currently in and then improve the soil in teh hole and for back flling with plenty of good garden compost and/or well rotted manure to help enrich its soil and moisture retention. Soak the pot in a bucket of water till no further bubbles appear then lift out and plant at the same depth. Water generously once planted and for the rest of this summer to get it established.

The paniculatas flower on new wood so you can prune yours to shape or size at the beginning of spring and it will then grow new stems and flower on those. Give it a good feed of pelleted chicken manure or bllod, fish and bone worked in around its roots every spring and it should be good for years.
