Best Plants for Pots and Containers UK

Best Container Plants

Containers are one of the easiest ways to add colour, fragrance and structure to patios, balconies, courtyards and small gardens. The key is choosing plants that thrive in restricted root space while continuing to perform throughout the growing season.

🌿 Lavender

Lavender Plug Plants are ideal for pots because they love well-drained conditions and sunny locations. Their fragrant foliage, attractive flowers and ability to attract bees make them a firm favourite for container displays. Lavender also provides evergreen structure during the winter months, helping containers look attractive all year round.

🌿 Agapanthus

Agapanthus Plug Plants are surprisingly well-suited to containers. In fact, they often flower better when their roots are slightly restricted. Their spectacular globe-shaped blooms rise above strappy foliage during summer, creating a striking focal point for patios and entrances.

🌿 Salvia

Salvia Plug Plants provide months of colourful flowers and are excellent for adding long-lasting colour to container combinations. Their upright flower spikes attract pollinators throughout summer and many varieties continue blooming until the first frosts.

🌿 Heuchera

Heuchera Plug Plants are grown primarily for their colourful foliage, which comes in shades of purple, silver, lime green, amber and deep burgundy. They perform exceptionally well in containers, providing year-round interest even when flowering plants are out of season.

🌿 Compact Ornamental Grasses

Compact grasses add movement, texture and structure to container displays. Their graceful foliage contrasts beautifully with flowering perennials and requires very little maintenance once established.

🌿 Rosemary

Rosemary is an excellent choice for sunny containers. Its evergreen foliage provides interest throughout the year, while its aromatic leaves can be used fresh in the kitchen. It also produces attractive flowers that are loved by pollinators.

🌿 Thyme

Thyme is perfect for smaller pots, hanging over the edges of containers and softening hard landscaping. This drought-tolerant herb thrives in sunny positions and provides both ornamental and culinary benefits.

Container Success Tips

Choosing the right plants is only part of the formula. A few simple container-growing techniques can dramatically improve performance.

Choose Larger Pots Where Possible

Larger containers hold more compost, retain moisture for longer and provide greater root space. This often results in healthier plants and reduces the frequency of watering during hot weather.

Use High-Quality Compost

Good quality compost provides the nutrients and structure plants need to establish quickly. Containers can quickly become depleted of nutrients, so starting with the best compost available will pay dividends throughout the season.

Water Consistently

Plants grown in pots dry out much faster than those planted in the ground. Regular watering is essential, particularly during warm summer weather. Containers positioned in full sun may require watering daily during hot spells.

Feed During the Growing Season

Adding a balanced liquid fertiliser every few weeks encourages stronger growth, improved flowering and healthier foliage. Heavy flowering plants such as Agapanthus Plug Plants and Salvia Plug Plants particularly benefit from regular feeding.

Create Professional-Looking Seasonal Displays

One of the secrets professional gardeners use is the "Thriller, Filler and Spiller" method.

Thriller Plants – Height and Drama

These are the plants that create impact and draw the eye.

Excellent thriller plants include:

• Agapanthus Plug Plants
• Compact ornamental grasses
• Upright Salvias

Filler Plants – Fullness and Colour

Fillers occupy the middle section of the container, providing colour and bulk.

Ideal fillers include:

• Salvia Plug Plants
• Heuchera Plug Plants
• Compact flowering perennials

Spiller Plants – Softening the Edges

Spillers cascade over the container rim, creating a softer and more natural look.

Popular choices include:

• Trailing Thyme
• Bacopa
• Lobelia
• Trailing Verbena

Combining these three elements creates balanced displays with interest at every level.
