Potentilla fruticosa 'Red Ace'
Potentilla Red Ace is a compact, hardy deciduous shrub that brings vibrant colour to any garden with its striking orange-red flowers. This versatile plant is beloved by gardeners for its exceptionally long flowering season, low maintenance requirements, and ability to thrive in challenging conditions. Perfect for beginners and experienced gardeners alike, Red Ace offers months of continuous colour with minimal fuss.
Red Ace stands out with its unique flower colour—whilst most potentillas produce yellow or white blooms, this cultivar displays beautiful orange-red petals with bright yellow centres. The flowers are small but numerous, creating a carpet of colour from late spring through to the first frosts. The neat, compact growth habit and attractive grey-green foliage make it an excellent choice for structured planting schemes.
Size: Typically reaches 0.5-1.0m in both height and spread, forming a neat, rounded mound
Flowers: Five-petalled, orange-red blooms approximately 2.5cm across
Foliage: Small, pinnate leaves in an attractive grey-green colour that provides excellent contrast to the flowers
Growth habit: Dense, bushy shrub with a naturally compact form requiring minimal pruning
Red Ace is remarkably adaptable and tolerates a wide range of growing conditions. It thrives in full sun to partial shade, though the flower colour is most intense in sunny positions. The plant is extremely hardy, tolerating temperatures well below -20°C, and is drought-tolerant once established. It's also salt-tolerant, making it suitable for coastal gardens.
Soil requirements: Adaptable to most soil types, including poor, sandy, or clay soils. Prefers well-draining soil but tolerates occasional waterlogging.
One of Red Ace's greatest assets is its exceptionally long flowering season. Blooms typically appear in late May or early June and continue non-stop until the first hard frosts in autumn. This extended display makes it invaluable for maintaining garden colour throughout the growing season. Deadheading spent flowers will encourage continued blooming, though it's not strictly necessary.
Red Ace is incredibly versatile in garden design. It works beautifully in mixed borders, providing structure and consistent colour amongst perennials. The compact size makes it perfect for small gardens, containers, or as a low hedge. It's excellent for wildlife gardens, attracting bees and other pollinators throughout its long flowering period. The plant also suits cottage garden styles, rock gardens, and Mediterranean-themed plantings.
This is truly a low-maintenance plant. Water regularly during the first growing season to establish a strong root system, then only during prolonged dry spells. An annual application of general-purpose fertiliser or compost in spring will promote healthy growth and abundant flowering.
Pruning is minimal—simply remove any dead, damaged, or crossing branches in late winter or early spring. The plant can be lightly shaped if desired, but its naturally neat habit rarely requires intervention.
Red Ace pairs beautifully with plants that complement its warm flower tones. Consider planting alongside lavender, rosemary, or ornamental grasses for a Mediterranean feel. It also works well with blue or purple perennials such as catmint, salvia, or hardy geraniums, creating pleasing colour contrasts. The grey-green foliage provides an excellent backdrop for brighter flowers.
Whilst primarily grown for its flowers, Red Ace offers year-round garden value. The attractive foliage provides structure during the growing season, whilst the woody stems add winter interest to the garden framework. In autumn, the leaves may take on subtle yellow tones before falling.
This outstanding shrub combines beauty, reliability, and ease of care in one compact package. Its unique flower colour, exceptional flowering period, and tolerance of challenging conditions make it an invaluable addition to any garden. Whether you're looking for consistent colour, wildlife value, or simply a beautiful, trouble-free plant, Potentilla Red Ace delivers on all counts.
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.

* 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.
