Berberis thunbergii 'Lime Star' - Compact Lime Barberry
Vibrant Lime-Green Deciduous Shrub for Contemporary Gardens
Overview
Berberis thunbergii 'Lime Star' is a striking compact barberry that brings brilliant lime-green foliage to the garden in a perfectly sized package for modern landscapes. This relatively new cultivar offers an exciting departure from traditional barberry colours, with bright lime-yellow to chartreuse foliage that maintains its vibrant intensity throughout the growing season. The naturally compact, rounded habit makes it ideal for smaller gardens, containers, and contemporary design schemes where bold colour impact is desired without overwhelming scale. Its exceptional colour brightness and neat growth habit make it invaluable for creating dramatic contrasts and modern garden focal points.
Key Features
Foliage: Small, oval leaves (2-3cm long) emerge brilliant lime-green in spring and maintain their vibrant chartreuse to lime-yellow colouration throughout the growing season. In autumn, foliage may develop orange and red tints before dropping.
Size: Compact, naturally rounded habit reaching 60-80cm in height and 60-80cm in spread when mature, making it perfect for smaller gardens and container cultivation.
Growth Rate: Slow to moderate growth rate, typically adding 10-20cm per year once established, naturally maintaining its compact proportions.
Flowers: Small, pale yellow flowers appear in late spring, blending harmoniously with the lime-green foliage and creating a cohesive colour display.
Thorns: Well-armed with sharp spines along the branches, providing security benefits despite its ornamental focus and compact size.
Berries: Small red berries may appear in autumn, though fruit production can be variable and is secondary to the foliage display.
Growing Conditions
Light Requirements: Performs best in full sun to partial shade. Full sun produces the most intense and vibrant lime-green colouration, whilst partial shade is tolerated but may result in slightly less brilliant colour intensity.
Soil: Extremely adaptable to virtually all soil types including heavy clay, chalk, sandy loam, and poor soils. Prefers well-draining conditions but tolerates both drought and occasional waterlogging. pH range 5.0-8.0.
Hardiness: Fully hardy throughout the UK (RHS hardiness rating H6), withstanding temperatures down to -20°C without protection.
Exposure: Good tolerance of wind and urban conditions, making it suitable for exposed sites and city gardens.
Planting and Care
Planting Time: Best planted in spring or early autumn for optimal establishment, though container-grown plants can be planted year-round in suitable weather conditions.
Spacing: Allow 80cm-1 metre between plants for mass planting or low hedging, or plant as individual specimens with adequate space to reach full size.
Watering: Water regularly during the first growing season to establish roots. Once established, demonstrates good drought tolerance though benefits from watering during prolonged dry periods.
Feeding: Apply balanced slow-release fertiliser in early spring to maintain healthy growth and optimal foliage colour intensity.
Pruning: Minimal pruning required due to naturally compact habit. If necessary, prune lightly in early summer after flowering to maintain shape. Always wear protective gloves when handling.

Contemporary Garden Trends
'Lime Star' perfectly captures current trends towards bold, unusual colours in garden design, bright foliage plants, and compact varieties suitable for smaller modern gardens and container cultivation.
Potential Considerations
The bright lime-green colour may not suit all garden styles or personal colour preferences. In very shaded conditions, foliage colour becomes less vibrant. The deciduous nature means winter interest relies on bare branch structure rather than foliage.

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.

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.
