In a previous series in growing plants in containers in the sun, trees, shrubs, perennials, and annuals were described and their suitability to been grown in containers. It is now to turn our attention to growing plants in containers who can support the shade, where sunshine can become a premium.
In this first article of the series shrubs and trees that can be grown in containers in the shade will be discussed, in terms of the suitability in containers and their preferred growing conditions. The problem is that the most colourful plants require some sun to bloom, but this does not restrict plants in the shade to leaves, as other flowering plants can flourish in these harsher conditions.
For autumn and winter wall planters use some young shrubs which produce pretty buds and berries. Once they outgrow the planter they can be moved to their own individual container. Shrub sizes can be controlled by clipping them into shape.
These shrubs can be underplanted with daffodils and muscari in autumn so that there is a blast of colour in early spring.
It is better to plant some larger shrubs or trees in containers as a sole specimen, to give a focal point of a more permanent structure to your shady container garden design.
What follows are shrubs and trees that will tolerate dark, shady conditions in your container garden:
ACER PALMATUM (Japanese Maple) ‘Bloodgood’
This deciduous tree can grow in full shade or full sun, it seems not to matter. The tree has dark reddish purple, maple-like leaves. The leaves themselves turn bright red in autumn and small, purple flowers are noticed in spring.
This 5m large tree would appreciate being grown in a soil based compost in a large pot. After flowering winged red fruits can be seen. It will need plenty of water, especially when it is establishing.
BUXUS SEMPERVIRENS (Box)
Another shrub which is perfectly happy to be grown in full sun or the shade. It is an evergreen shrub that has a dense population of small oval, bright green leaves. It is usually planted in a large container filled with a soil-based compost, where it will grow up to 1m in height. Topiary can be practiced on the shrub and you can make any number of shapes both regular and irregular.
CAMELLIA x WILLIAMSII
This large evergreen shrub can grow up to 5m in height. It has glossy bright green leaves. In spring numerous pink, red or white flowers are produced. The best variety to grow in containers is ‘Donation’, which has pink, semi-double flowers.
A large container of ericaceous compost is required for the shrub to flourish.
CHOISYA TERNATA (Mexican Orange Blossom) ‘Sundance’
This is yet another shrub that is content to grow in the sun or shade. It is an evergreen shrub that has a tendency to be round in shape. The aromatic glossy leaves are bright green when older but golden whilst young.
The small white flowers that open in late spring and autumn (it can flower twice a year) are fragrant. Grow it in a soil-based compost in a large container where it will grow up to 2.5m in height.
CLETHRA ALNIFOLIA (Sweet Pepper Bush)
This deciduous shrub grows up to 2.5m in height. It has oval, serrated, mid-green leaves, and from late summer to early autumn, spikes of fragrant, white, bell-shaped flowers are produced. It appreciates being grown in a large container filled with ericaceous compost. This is one plant which will survive total shade.
FATSIA JAPONICA (Castor Oil Plant)
Yet another shrub that can be grown in full sun or in the shade. It is an evergreen shrub with large, glossy hand-shaped dark green leaves. In autumn small, spherical, white flower heads are produced, which are followed by black berry-like fruits. Plant in a large container of soil-based compost where it will grow up to 2m in height.
This tall bushy deciduous shrub grows up to 75cm in height. This fuchsia has large oval, pointed, golden-green leaves. From summer to autumn, single or double, pendant, cerise, and purple flowers are produced. It will need protection from cold winds especially northerlies and Easterlies Plant it in a container full of a soil-based compost.
Other possibilities include fuchsia ‘Doctor Foster’ and fuchsia ‘Mrs Popple’.
FUCHSIA ‘Tom Thumb’
This relatively short fuchsia grows up to 50cm in height. Like all fuchsia, it is deciduous with dark, green, oval foliage. In summer until autumn, a mass of pendant bell-shaped, red and mauve-blue flowers are produced. It is small enough to be grown in pots, window boxes and hanging baskets in a soil-based compost.
GAULTHERIA PROCUMBENS (Checkerberry)
A dwarf, evergreen shrub that only grows up to 15cm in height. It has oval, leathery leaves that are tinged red in winter. In summer small pink-white flower appear, which are followed by scarlet coloured berries. You can use them in window boxes, or winter hanging baskets using ericaceous compost.
HEBE ‘Red Edge’

It needs to be planted in a sheltered site, where it appreciates being in a pot of soil-based compost. Trim flowers after flowering to keep neat and tidy.
HELIOTROPIUM ARBORESCENS ‘Cherry Pie’
This is an evergreen shrub that is often grown as an annual. It is a short shrub only growing to 45cm in height with its oval, dark green crinkly leaves. The clusters of purple or white flowers are fragrant and produced throughout the summer months. Plant in pots near the front door in multipurpose compost to enjoy the fragrance.

A large pot of soil-based compost is required in order for the plant to produce its display. ‘Lady in Red’ is the preferred specimen to grow in pots.
RHODODENDRON YAKUSHIMANUM ‘Yakushima Rhododendron’
This 2m tall evergreen compact shrub, has leathery, green leaves that are felted underneath. The flowers are bell-shaped and are white with a pink hue. They are produced in spring when grown in its preferred ericaceous compost. The roots do not like to be dry, so water well in dry weather. An alternative could be Rhododendron impeditum.

In spring clusters of fragrant, white flowers are produced, which are followed by red berries if a female species are planted. Males only produce flowers and no berries. Plant in a soil based compost and enjoy the scent.
Skimmia x confuse ‘Kew Garden’ can be used as an alternative.
In this article, shrubs and trees that can be grown in containers in the shade have been discussed. What is noticed is that some shrubs can be planted either in full sun or full shade, whilst others will tolerant shade very well.
The range of plants to use compared to full sun is more limited, but a full range of plants can be used. These plants cover different leaf shapes, flower forms, and colours. No matter what there is a tree or shrub for you.
