Santolina chamaecyparissus (Cotton Lavender)

Overview

Cotton Lavender is a charming Mediterranean perennial that brings year-round structure and silvery beauty to any garden. Despite its common name, this delightful shrub isn't actually related to lavender but earns its moniker from the wonderfully aromatic, finely textured foliage that resembles tiny silver threads. Perfect for creating low hedges, filling rockeries, or adding texture to mixed borders.

 

Key Features

Botanical Name: Santolina chamaecyparissus
Common Names: Cotton Lavender, Lavender Cotton, Gray Santolina
Plant Type: Evergreen perennial shrub
Mature Size: 10-50cm height × 0.5-1.0m spread
Hardiness: RHS H5 (Hardy down to -10°C to -15°C)

 

Appearance & Characteristics

Foliage

The star attraction of Cotton Lavender is its distinctive silvery-grey foliage. The leaves are deeply divided and densely packed, creating a soft, woolly texture that's irresistible to touch. This evergreen shrub maintains its ornamental value throughout the year, providing constant structure in the garden even during winter months.

Flowers

In midsummer (July to August), Cotton Lavender produces masses of bright yellow, button-like flowers held on slender stems above the foliage. These cheerful blooms are approximately 1.5cm across and create a lovely contrast against the silver leaves. The flowers are excellent for cutting and add a Mediterranean flair to bouquets.

Fragrance

Both the foliage and flowers are highly aromatic, releasing a distinctive camphor-like scent when brushed against or crushed. This natural fragrance helps deter insects and adds another sensory dimension to your garden experience.

 

Growing Conditions

Sunlight Requirements

Cotton Lavender thrives in full sun and requires at least 6 hours of direct sunlight daily for optimal growth and flower production. In partial shade, the plant becomes leggy and produces fewer flowers.

 

Soil Preferences

This adaptable plant prefers well-draining soil and is remarkably tolerant of poor, sandy, or chalky conditions. It actually performs better in nutrient-poor soils than in rich, fertile ground. Excellent drainage is essential, as the plant cannot tolerate waterlogged conditions.

 

Climate Tolerance

Exceptionally drought-tolerant once established, Cotton Lavender is perfect for xerophytic gardens and requires minimal watering. It's also highly tolerant of coastal conditions, including salt spray and windy locations.

 

Care Instructions

Planting

Plant in spring or early autumn, spacing plants 45-60cm apart for hedging or allowing 90cm for specimen plants. Dig in some grit or sand if your soil is heavy clay to improve drainage.

Watering

Water regularly during the first growing season to establish roots. Once established, supplemental watering is rarely needed except during prolonged dry spells.

Pruning

Prune annually in late spring (May) to maintain shape and encourage dense growth. Cut back by one-third to one-half, but avoid cutting into old wood as this may not regenerate. Regular light trimming throughout the growing season helps maintain a compact habit.

Fertilising

Generally requires no additional feeding. In fact, too much fertiliser can cause the plant to become soft and lose its characteristic compact form.

 

Garden Uses

Design Applications

  • Low hedging: Creates beautiful informal hedges 30-45cm high

  • Border edging: Perfect for defining pathways and garden beds

  • Rockeries: Excellent for adding structure to rock gardens

  • Mediterranean gardens: Essential component of drought-tolerant planting schemes

  • Container growing: Suitable for large pots and planters

  • Cottage gardens: Adds traditional charm with its silver foliage

 

Companion Planting

Pairs beautifully with other Mediterranean plants such as rosemary, thyme, salvia, and true lavender. The silver foliage provides excellent contrast to purple and blue flowers, and complements ornamental grasses wonderfully.

 

Benefits for Wildlife

The summer flowers attract beneficial insects including bees, butterflies, and hoverflies. The aromatic foliage naturally deters many garden pests, making it a useful companion plant for vegetable gardens.

 

Potential Considerations

  • May self-seed prolifically in ideal conditions

  • Can become woody and sparse if not pruned regularly

  • Not suitable for very wet or poorly drained soils

  • May be damaged by temperatures below -15°C

 

Varieties to Consider

Several cultivars offer slight variations in size and foliage colour, including 'Nana' (a more compact form) and 'Edward Bowles' (with particularly fine, silvery foliage).

 

Summary

Cotton Lavender is an invaluable addition to any sunny garden, offering year-round interest with minimal maintenance requirements. Its drought tolerance, pest-deterrent properties, and structural beauty make it particularly suited to modern, sustainable gardening approaches. Whether you're creating a formal hedge, filling a difficult dry spot, or simply want to add Mediterranean charm to your borders, this reliable performer delivers season after season.

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.

Berberis thunbergii 'Admiration' 

 

Overview

Berberis thunbergii 'Admiration' is a compact, deciduous barberry that brings year-round interest to gardens with its striking foliage and neat, rounded habit. This dwarf cultivar is particularly prized for its vibrant red-orange leaves edged with a delicate golden-yellow margin, creating a glowing effect in borders and containers alike. Perfect for the gardener seeking low-maintenance colour and structure, 'Admiration' offers exceptional garden performance in a manageable size.

 

Key Features

This outstanding barberry combines ornamental appeal with practical benefits. The small, oval leaves emerge in spring with intense colouring that deepens through summer, whilst the distinctive golden rim remains prominent throughout the growing season. In autumn, the foliage transforms into brilliant shades of scarlet and crimson before dropping to reveal an attractive branching structure. Small, pale yellow flowers appear in late spring, followed by glossy red berries that persist into winter, providing valuable food for birds.

 

Size and Growth Habit

'Admiration' is a true dwarf variety, typically reaching 40-50cm in height with a similar spread, making it ideal for smaller gardens, front-of-border positions, or container cultivation. Its naturally compact, rounded form requires minimal pruning to maintain its shape. Growth is relatively slow and controlled, adding approximately 10-15cm per year once established.

 

Planting Position

This versatile barberry thrives in full sun to partial shade, though the most intense leaf colouring develops in sunny positions with at least four to six hours of direct sunlight daily. It tolerates a wide range of soil types, including clay, chalk, and sand, provided drainage is reasonable. 'Admiration' is remarkably hardy, withstanding temperatures down to -20°C, and shows good tolerance of urban pollution, coastal conditions, and exposed sites.

 

Care and Maintenance

One of the great advantages of 'Admiration' is its undemanding nature. Once established, it requires little attention beyond occasional watering during prolonged dry spells in the first growing season. The plant is drought-tolerant once its root system is developed. Pruning is optional but can be carried out in late winter or immediately after flowering if you wish to maintain size or shape. Wear thick gloves when handling, as the stems bear sharp thorns.

Feed annually in early spring with a general-purpose fertiliser or a mulch of well-rotted organic matter to encourage healthy growth and vibrant foliage colour.

 

Garden Uses

The compact size and vivid colouring of 'Admiration' make it suitable for numerous garden situations. It excels as a low hedge or edging plant, creates striking colour contrasts in mixed borders, and works beautifully in rock gardens or gravel gardens. The plant is equally at home in patio containers, where its year-round interest can be appreciated up close. The thorny branches also make it useful for deterring unwanted access whilst adding ornamental value.

Pair 'Admiration' with purple heucheras, silver artemisias, or blue-leaved hostas for compelling colour combinations, or mass-plant for a bold, unified statement.

 

Hardiness and Resilience

RHS Hardiness Rating: H6 (hardy throughout the British Isles). This barberry is exceptionally tough, resisting pests and diseases with minimal intervention. It rarely suffers from significant problems and shows good resistance to common barberry rust. Deer tend to avoid it due to the thorny stems, making it suitable for rural gardens where browsing can be problematic.

 

Summary

Berberis thunbergii 'Admiration' is an outstanding choice for gardeners seeking a low-maintenance, high-impact shrub that performs reliably in various conditions. Its jewel-like foliage, compact habit, and year-round appeal make it a valuable addition to gardens of any size, whilst its resilience ensures success even for less experienced gardeners.
