Small Evergreen Shrubs for Pots: Year-Round Colour and Structure

Best Small Evergreen Shrubs for Pots

A pot by the front door or on the patio looks less bare in winter when it contains an evergreen shrub. Compact hebes, variegated euonymus and dwarf conifers are useful choices, giving you foliage and shape throughout the year. Choose plants that grow slowly or respond well to light pruning, and allow enough room in the container for healthy root development. Seasonal bedding can be added around the edges where space permits.

When you are choosing evergreen shrubs for pots, look at the eventual height and spread. A shrub that wants to reach 3 metres will quickly outgrow a 40cm container. Stick to varieties that mature at roughly 1 metre or less, or those that respond well to an annual trim. The selection below includes compact shrubs as well as taller conifers and pieris that suit larger containers. Check the eventual height and spread before planting, as some will need repotting or pruning as they mature.

Pay attention to the light your pot will receive. Wilma Goldcrest and many dwarf conifers prefer bright positions, while euonymus tolerates some shade. Hebes generally flower best with plenty of light and a sheltered position, particularly in colder gardens. Match the shrub to the spot, and you will have a healthy plant that needs little intervention beyond watering and an occasional feed.

Dwarf Conifers and Wilma Goldcrest

Dwarf conifers are classic evergreens for pots. They grow slowly, keep a neat shape without much pruning, and provide texture through winter. Mixed dwarf conifers can include different growth habits, from low, rounded plants to upright forms. Check the mature height and spread of each plant before arranging them, so the larger growers do not crowd out their neighbours. Our mixed dwarf conifers come in several pack sizes: you can start with four plants in 9cm pots, or choose a set of six in 2 litre pots for a more established look. Larger packs of 12 or 18 potted plants are useful if you want to fill several containers at once.

Wilma Goldcrest is a standout conifer for a single specimen pot. Its bright lime-green foliage has a lemony scent when brushed, and its narrow, conical habit makes it a natural focal point. Wilma Goldcrest is available as a single plant in a 2 litre pot. In a larger container it may grow roughly 10 to 20cm a year under suitable conditions, although its eventual height is not limited to 1.5 metres. Allow space for its upright growth and trim lightly if needed. You can also buy Wilma Goldcrest in packs of 6, 12 or 18 smaller plants, which is handy if you want a matching row of pots along a path or balcony.

Both dwarf conifers and Wilma Goldcrest need free-draining compost and a sunny spot. Water them regularly during the first growing season so the roots spread into the new compost. Once established, they are fairly drought-tolerant but will suffer if left to sit in waterlogged soil. A top dressing of gravel helps keep the surface dry around the crown.

Hebes, Heathers and Euonymus

Hebes are some of the most reliable evergreen shrubs for pots, particularly in coastal or milder areas. They have glossy leaves and produce spikes of purple, pink or white flowers in summer. Hebe Red Edge is a compact variety with grey-green foliage that takes on a reddish margin in cold weather, giving you two seasons of interest from one plant. It is sold in 9cm pots, with options for 2, 3, 4 or 6 plants. A group of three planted in a wide, shallow bowl makes a full, mounded display within a year.

Mixed hebes give you a selection of leaf colours and flower shades, all with the same easy-care habit. They are available as 4 plants in 2 litre or 9cm pots, or in larger packs of 6, 12 or 18 plants in 9cm pots. Space them about 30cm apart in a container for a dense, shrubby planting that flowers from midsummer into autumn.

Euonymus Emerald 'n' Gold and Emerald Gaiety are tough, variegated evergreens that light up a shady corner. Emerald 'n' Gold has green and gold leaves with a pinkish tinge in winter. Emerald Gaiety is green and white, and its trailing habit works well at the edge of a pot. Both are available as single plants in 2 litre pots, and Emerald 'n' Gold also comes in a 9cm pot. They grow about 10 to 15cm a year and can be clipped lightly in spring to keep them bushy.

Mixed garden heathers bring low evergreen foliage and small flowers to containers. Packs contain 6, 12 or 18 plants in 9cm pots, giving you enough for several individual pots or a wider trough. Flowering times depend on the varieties included, so colour may appear at different points in the year. Most heathers prefer a sunny position, but check the species before choosing compost, as some tolerate lime while others require acidic conditions. Trim lightly after flowering without cutting into old, bare wood.

Ericaceous Shrubs in Pots

Several small evergreen shrubs need acidic soil, which makes them perfect candidates for pots. You can give them exactly the ericaceous compost they require without trying to alter your garden soil. Dwarf evergreen azaleas, mixed Japanese azaleas, mixed dwarf rhododendrons, Pieris Forest Flame and Pieris Mountain Fire all fall into this group.

Dwarf evergreen azaleas are sold as single plants in 2 litre pots, in a choice of colours. They form neat, rounded bushes covered in flowers in late spring. Mixed Japanese azaleas are available as 4 plants in 9cm pots, or as 4 or 6 plants in 2 litre pots. They are slightly more compact and often flower a little earlier. Both types keep their leaves through winter, though some may take on bronze tones in cold weather.

Mixed dwarf rhododendrons give you larger leaves and trusses of bell-shaped flowers in spring. You can buy them in 9cm pots (packs of 6, 12 or 18) or in 2 litre pots (packs of 3, 4 or 6). They are slow-growing and will live happily in a pot for many years if you repot them every two to three years into fresh ericaceous compost.

Pieris Forest Flame and Pieris Mountain Fire are grown for their dramatic new growth. Forest Flame produces bright red young leaves that fade to pink, cream and then green. Mountain Fire has coppery-red new shoots. Pieris Mountain Fire is available as a single plant in a 2 litre pot. Pieris Forest Flame is also available as a single 2 litre plant, alongside options for 6, 12 or 18 plants and a separate pack of 6 plants in 2 litre pots. The pot or root specification for the other Forest Flame multipacks is not stated in the catalogue. They like partial shade and shelter from cold winds, which makes a pot in a courtyard or against a wall ideal.

Pot Size, Compost and Watering

Choosing the right pot and compost is as important as choosing the shrub itself. A container that is too small will restrict roots and dry out quickly. A pot that is too large can hold too much wet compost in winter, leading to root rot. As a rule, start a young shrub in a pot that is 5 to 8cm wider than the nursery pot it arrives in. Move it up a size every two to three years as it grows.

For most small evergreen shrubs, a loam-based compost such as John Innes No 2 is ideal. It holds nutrients well, drains freely and gives the pot some weight, which stops it blowing over. For ericaceous plants (azaleas, rhododendrons, pieris, heathers), switch to an ericaceous John Innes compost. Avoid using garden soil in pots: it compacts, drains poorly and may introduce weeds or diseases.

Watering is the single biggest task with shrubs in pots. In summer, a container can dry out in a day. Check the compost with your finger; if the top 2 to 3cm feels dry, water thoroughly until it runs out of the drainage holes. In winter, reduce watering but never let the compost dry out completely. Evergreens lose water through their leaves even in cold weather, so they still need some moisture at the roots.

Feeding keeps potted shrubs healthy. From March to August, apply a balanced liquid feed every two to four weeks. For ericaceous shrubs, use a feed formulated for acid-loving plants. A controlled-release fertiliser mixed into the compost in spring is a good low-maintenance alternative. Stop feeding by early September so any soft new growth has time to harden before frosts.

Winter Care for Potted Shrubs

Evergreen shrubs in pots face two main winter challenges: frozen roots and wind scorch. The roots are above ground and far more exposed than they would be in a border. A few simple steps will see them through the coldest months.

First, raise the pot onto feet or bricks so excess water can drain away. A pot sitting in a puddle of frozen water can split, and the roots will suffer. Second, wrap the pot with bubble wrap, hessian or a purpose-made pot jacket. This insulates the rootball against sharp temperature swings. Third, group pots together in a sheltered spot, ideally against a house wall, where they benefit from radiated heat and reduced wind.

Snow is not usually a problem for small evergreens, but a heavy fall can splay branches. Knock snow off gently with a broom to prevent breakage. Do not use salt or chemical de-icers near pots, as the run-off can damage roots and foliage.

If a prolonged freeze is forecast and the compost is dry, water sparingly on a mild day. Moist compost holds more heat than dry compost, so a light watering before a freeze can actually protect roots. Avoid feeding in winter, as the plants are not actively growing.
