The Albizia 'Ombrella' is an enchanting deciduous tree that brings an exotic, tropical feel to British gardens. Also known as the Silk Tree or Mimosa Tree, this graceful specimen is prized for its delicate, feathery foliage and spectacular powder-puff flowers that create a truly magical display. Despite its exotic appearance, 'Ombrella' is surprisingly hardy and adaptable, making it an excellent choice for gardeners wanting to add something special and unusual to their landscape.
This stunning tree showcases incredibly fine, bipinnate leaves that create a soft, ferny texture reminiscent of tropical vegetation. The foliage has a unique characteristic of folding up at night or in poor weather, earning it the nickname "sleeping tree." From mid to late summer, the tree produces masses of silky, pink powder-puff flowers with prominent stamens that create an almost ethereal appearance. The flowers are followed by attractive flat seed pods that add further interest through autumn.
'Ombrella' thrives in a warm, sheltered position with full sun exposure and protection from strong winds. It requires well-drained, fertile soil and benefits from a sunny, south-facing location, ideally with some shelter from buildings or other trees. In colder regions, consider planting against a warm wall or in a courtyard garden where it can benefit from reflected heat and wind protection. Good drainage is essential, as the tree dislikes waterlogged conditions.
This exotic beauty requires more attention than typical British trees, particularly when young. Water regularly during dry spells, especially in the first few years whilst the root system establishes. Apply a balanced fertiliser in spring and consider mulching around the base to retain moisture and protect roots from frost. In colder areas, wrap young trees with fleece during harsh winter weather. Pruning should be minimal and carried out in late spring after the last frost, removing only dead, damaged, or crossing branches.
'Ombrella' makes a spectacular specimen tree, perfect as a focal point in lawn areas or large borders. Its exotic appearance makes it ideal for Mediterranean-style gardens, courtyard plantings, or contemporary landscape designs. The tree works beautifully in sheltered city gardens where the microclimate provides additional warmth. It's also excellent for creating dappled shade whilst maintaining an open, airy feel due to its fine foliage texture.
This distinctive tree pairs wonderfully with other Mediterranean and exotic plants such as olive trees, palms, or bamboos to create a tropical garden theme. Underplant with drought-tolerant perennials like lavender, rosemary, or ornamental grasses. For a more traditional approach, combine with other flowering trees such as magnolias or cercis, which share similar growing requirements.
The abundant, nectar-rich flowers are highly attractive to bees, butterflies, and other pollinators during the peak summer months when many other flowers have finished. The tree provides excellent habitat for birds, who often nest in its spreading branches, whilst the seed pods may attract seed-eating birds in autumn.
Whilst hardy in most of southern England, 'Ombrella' benefits from a sheltered position and may require winter protection in exposed or northern locations. Young trees are more vulnerable to frost damage, so consider container growing initially or providing winter protection for the first few years. The tree may be slow to leaf out in spring, often not showing new growth until late spring or early summer.
This remarkable tree offers the opportunity to grow something truly unique in the British climate. Its exotic appearance, spectacular flowers, and interesting foliage behaviour make it a real conversation piece that will amaze visitors to your garden. Whilst it requires a bit more care than native species, the stunning results make the effort worthwhile for gardeners seeking something special and distinctive. Perfect for those wanting to create a Mediterranean or exotic garden theme whilst still working within our climate constraints.
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.
Pre-order: Pre-order times are given as a guide only and may vary dependent on the growing season. 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.
