Seasonal Garden Colour

My aim here is to show that you can enjoy colour from plants all through the year. Why so many gardens are devoid of colour in winter I do not know, for there are many suitable plants to choose from. Indeed, the en-tire list represents only a fraction of those available for each season of the year. But they have been chosen on their merits – they are among the very best garden plants available.

The list has been divided into spring, summer, autumn and winter, and each season contains a selection of perennials, shrubs and trees. Some are noted for flowers, others for coloured foliage, coloured stems, berries or autumn leaf colour.

SPRING

Perennials

Bergenia

(Pig-squeak) Dwarf perennials, all worth growing for their early blooms in shades of red, pink or white, which show up well against the large, leathery. Shiny leaves. Ideal plants for shady spots and moist soil, although highly adaptable to other sites.

Dicentra spectabilis

(Bleeding heart) A dwarf perennial for shade and moist soil, producing sprays of rosy-red flowers with white hips in late spring and early summer. The ferny foliage is attractive, too. A delightful white-flowered form is also available and well worth searching for.

Doronicam

(Leopard’s bane) An indispensable dwarf perennial with yellow daisy flowers. Good varieties are ‘Miss Mason’ and the deep yellow, fully double-flowered ‘Spring Beauty’. Provide good drainage and sun. but otherwise this little plant is very easygoing.

Euphorbia epithymoides

(Spurge) Another excellent dwarf perennial for early blooms, which are acid yellow. It likes sun and moist yet well-drained soil.

Primula denticulata

(Drumstick primrose) My favourite primula, very easily grown in moist soil and shade or partial shade. It produces globular mauve (or white) flower heads on 30cm (1ft) high stems, grows vigorously and increases rapidly.

Shrubs and trees

Berberis darwinii

(Barberry) A medium-sized evergreen shrub with small holly-like leaves, this is one of the most popular barberries, with deep golden flowers in spring. Full sun and well-drained soil needed for best results.

Chaenomeles superba

‘Firedance’ (Ornamental quince) A medium-sized shrub grown for its glowing red single rose-like flowers. It needs good drainage and a position in sun or partial shade.

Several euphorbias or spurges flower in spring or early summer. Here’s an attractive combination of a lime-green spurge with E. griffithii ‘Fireglow’.

Choisya ternata

(Mexican orange blossom) A medium-sized evergreen shrub noted for its masses of scented white flowers over a very long period. Provide sun, good drainage and shelter from cold winds.

Forsythia

‘Lynwood’ (Golden bells) No garden is complete without forsythia, which makes a magnificent show of bright yellow blooms. ‘Lynwood’ is undoubtedly the best, with masses of large blooms. A medium-sized shrub; likes sun and good drainage.

Pieris formosa forrestii

A large evergreen shrub for acid soils and partial shade, which is grown as much for its brilliant red young leaves as for its long trusses of scented white spring flowers. A good form is ‘Wakehurst’ with brilliant red young foliage.

Prunus

‘Amanogawa’ (Ornamental cherry) Ornamental cherries are the very essence of spring, but most are too large for many gardens. Not so ‘Amanogawa’ which forms a slim column, clothed with pink blossoms. Needs a sunny, well-drained spot.

Viburnum tinus

(Laurustinus) An extremely useful medium to large shrub, with deep green evergreen leaves and masses of white flowers in the late winter or spring. An excellent variety is ‘Eve Price’ with carmine flower buds. Grows in full sun or partial shade and any well-drained soil. A good choice on chalk.

SUMMER

Perennials

Campanula lactiflora

(Bellflower) A 90cm (3ft) high perennial with lavender-blue bell-shaped blooms, ideal for a ‘blue border’. Grows in sun or partial shade and any moist but well-drained soil.

Festuca glauca

(Fescue grass) A dwarf blue-grey grass which has many uses as a foliage plant. It is evergreen, needs good drainage, and a sunny position for best colour.

Hemerocallis

(Day lily) The day lilies are invaluable for their exceedingly long season of flowering – continuing well into autumn. The grassy foliage is attractive, too. There are dozens of varieties in many colours – something for all colour schemes. Provide well-drained yet moist soil, and a position in sun or partial shade.

Hosta sieboldiana

‘Elegans’ (Plantain lily) The hostas are low-growing foliage plants, though they do produce lilac or white blooms in summer. Some have variegated foliage, others golden, yet others greyish or bluish, like ‘Elegans’, with very large bluish leaves. Hostas need moist soil and are ideal for cool shady spots.

Phlox paniculata

Border phlox) Like the day lilies, the phloxes are indispensable border plants, flowering for a long period. Rhere are many colours to choose from so they can be incorporated into any colour scheme. They are of medium height, like good drainage yet moist soil, and thrive in sun or partial shade.

Shrubs and trees

Acer negundo

‘Variegatum’ (Box elder) A medium-sized deciduous foliage tree with light green leaves boldly edged white, giving overall a very light effect. Very adaptable, for sun or partial shade.

Buddleia davidii

(Butterfly bush) Medium-sized shrub grown for its long spikes of flowers in various colours. ‘Royal Red’ is very popular, with red-purple blooms. Grows in any soil but likes full sun.

Cotinus coggygria

‘Royal Purple’ (Smoke tree) Distinguished for its lovely, plume-like in-florescences and one of the best purple-leaved shrubs, it makes a large, freely-branching specimen but can be kept smaller by careful pruning. Grows in any well-drained soil and either in full sun or partial shade.

Escallonia

Small or medium-sized evergreen shrubs grown for their flowers, in shades of red, pink or white carried over a long period. Any of the ‘Donard’ varieties are well worth growing. Any well-drained soil in full sun is suitable.

Gleditsia triacanthos

‘Sunburst’ (Honey locust) One of the best medium-sized golden trees, with bright yellow young foliage. Give it a site in full sun for the best colour and a well-drained soil. An excellent choice for town gardens.

Philadelphus

(Mock orange) Popular small or medium-sized shrubs with white flowers in early summer often heavily scented. Well-known varieties are ‘Beauclerk’, ‘Belle Etoile’ and ‘Virginal’. Provide full sun but any soil is suitable.

‘Aureus’ (Golden mock orange) One of the most popular golden-foliage shrubs for a position in full sun. A medium-sized shrub.

Pyrus salicifolia

Robinio pseudoacacia

‘Frisia’ (False acacia) A small to medium-sized tree with deep golden foliage, the colour lasting well right through to autumn. Full sun and good drainage.

AUTUMN

Perennials

Anemone x hybrida

(Japanese anemone) Late-flowering short to medium perennial, which blooms for a long period. Colours are white or shades of pink. Among the best varieties are ‘Bressingham Glow’ (rose-pink) and ‘September Charm’ (soft pink). Takes partial shade. Good on chalk soils.

Sedum spectabile

(Stonecrop) Dwarf perennial with flat heads of flowers over a long period, light pink in the species, and salmon-pink in variety ‘Autumn Joy’. Provide full sun and well-drained soil.

Shrubs and trees

Acer palmatum

(Japanese maple) Marvellous small, medium or large shrubs, depending on variety, for autumn leaf colour. Provide a sheltered spot and partial shade. The Dissectum varieties have ferny leaves, while the Heptalobum group has deeply lobed leaves. One of the best is ‘Heptalobum Osakazuki’ whose leaves turn a brilliant flame colour in autumn.

Chaemaecyparis pisifera

‘Boulevard’ (Sawara cypress) One of the dwarf conifers — must be the most popular of those with grey-blue foliage. Forms a neat broad cone shape. Best in slightly acid soil, and full sun or partial shade.

Cornusalba

‘Sibirica’ (Westonbirt dogwood) The best of the red-stemmed, shrubby dogwoods, with bright crimson bark. Cut the plant almost to ground level in early spring each year to encourage plenty of new shoots. Ideal for moist soil and especially recommended for poolside planting.

Elaeagnus pungens

‘Maculata’ A medium-sized evergreen shrub with large leaves conspicuously splashed in the centre with gold. Adaptable but will not grow too well in shallow chalky soils. Needs plenty of sun.

Erica herbacea (E. carnea)
