Shrubs in Tubs

Pieris japonica ‘Katsura’
Stunning mahogany-red new leaves. Sprays of crimson stained flowers in early spring. Plant in lime-free compost. 3ft x 2ft (90cm x 60cm)
By planting up pots and containers with evergreen shrubs, you’ll create longer lasting displays that provide interest all year round.
Many shrubs make wonderful long-term subjects for pots and, unlike seasonal bedding plants they can provide color and interest throughout the year. Although the initial outlay may be more than your usual seasonal selection, in the long term they are better value and far more rewarding. I grow a wide variety of shrubs in pots and use them to bring the garden onto the terrace, driveway and any other paved areas where planting in the ground is not feasible.
They make great focal points, and the wonderful thing about growing in pots is that you can change the planting picture so easily by moving them around, or by grouping them with a pot of bulbs, violas or perhaps a geranium or verbena for summer color.

Pittosporum tenuifolium ‘Variegatum’
Dense and bushy with waved, blue-green leaves edged with cream. Good in sun or shade. 4ft x 2ft (1.2m x 60cm)
Growing in pots also enables you to grow those shrubs that you long for, but will not succeed on your soil. For example camellias make wonderful shrubs for pots; you can grow them in this way if you have alkaline soil and cannot grow them in the open ground. I particularly like Camellia ‘Jury’s Yellow’ with its pale outer petals and gorgeous lemon-yellow central ruff.

Colorful foliage

Berberis thunbergii f. atropurpurea ‘Admiration’
Orange-red leaves in early spring, turning red, edged gold in summer, flame in late autumn. Bright red berries in winter. Deciduous. 18in x 18in (45cm x 45cm)
As with any planting solution I believe that foliage interest is more important than flowers; it is more enduring and lasts through the seasons. Flower color is easy to add on a temporary basis. If you get the combination of pot and foliage right, the effect can have so much more impact than a plant in an unsuitable container. Fortunately terracotta pots are very forgiving and work well with a wide variety of colors.
However they are perhaps at their best with the warm tones of red leaves and stems. I often use Cornus sanguinea ‘Midwinter fire’ or Acer palmatum ‘Sango-kaku’ in a terracotta pot on the terrace in winter. The latter, known as the coral-bark maple is stunning when the sun catches its red twigs with the warm tones of the clay.

Prunus incisa ‘Kojo-no-mai’
Pink buds open to delicate white flowers in early spring. Leaves turn scarlet in autumn. Gives the effect of a bonsai grown in a pot. Deciduous. 3ft x 2ft (90cm x 60cm)
Glazed ceramic pots are widely available and are a great way of adding color to your garden. They offer wonderful opportunities to get creative with your planting. Imagine the shimmering silver leaves and white trumpet flowers of Convolvulus cneorum with a blue or black glazed pot, for example.

Fatsia japonica
Large, dark green leaves and striking white flowerheads in winter. Great for a tropical effect in shade. ‘Variegata’ has leaves tipped with creamy white. 4ft x 3ft (1.2m x 90cm)
6.    Euonymus japonicas ‘Green Rocket
Long-term success
When it comes to planting up your container, I recommend that you choose a pot that the shrub is going to be happy in for a few years. If you use the right compost and feed and water regularly, a shrub can be happy in the same pot for five to ten years, or even longer.
The secret of success is to choose nice, big, good quality pots at the outset. I promise you, they always look a lot bigger at the garden center than they will when you get them home.

Euonymus japonicas ‘Green Rocket’
Upright stems packed with rounded dark green shining leaves. Striking and architectural. Ideal for small, modern shady gardens. 3ft x 1ft (90cm x 30cm)
The sizes of plants quoted here are approximate in five years. Eventual size can be larger but can be restricted by pruning or trimming; growing in containers normally restricts the size anyway. All are evergreen unless stated otherwise.
