Give your garden a professional edge by using the plants the experts choose for their great looks and reliability
London gardeners can learn from garden designers who need to use plants that look great, are easy to maintain and have a long season. What do the pros plant over and over in London gardens? For limited spaces, they choose small trees with big impact.

Designer Charlotte Rowe loves multi-stemmed Himalayan birch, Betula utilis var jacquemontii. “With its silvery-white trunk and diaphanous upper reaches, it looks great in both summer and winter, and is perfect for small spaces, including roof terraces.” Multi-stemmed Amelanchier lamarckii is another favourite of hers. “It provides early blossom, has a great form in winter and is tough as old boots.”

Fillers such as ground cover geraniums are indispensable. “Good old Alchemilla mollis is wonderful,” says Rowe. “It mixes well with lavender, santolina and many other plants to create a frothy, lime-green background through May and June.”

Claire Mee, like every London garden designer, puts evergreen Trachelospermum jasminoides at the top of her climbers list.

“Clients don’t want plants that drop leaves or look messy, and this keeps its shape. The flowers are white, pretty and smell of jasmine. I’ve used it as ground cover, pinning it along the ground.”

Many designers favour the elegant multi-stemmed Himalayan birch
She frequently plants the felty-leaved shrub Brachyglottis Sunshine. “It’s a useful evergrey with a soft, light appearance that needs clipping to keep in shape. I use olive trees a lot, too, because they have silky leaves that bring light into the garden.”

Lilies are not the only summer bulbs. “I put Gladiolus murielae in every garden I do,” says Philip Nixon. “They have a wonderful scent, are moderately tall and look beautiful planted en masse, drifting through grasses. Plant the bulbs early or start them in a greenhouse. They may not survive a damp winter but they are cheap to buy.”

Hydrangea arborescens Annabelle is a favourite of several garden designers, including Sara Jane Rothwell. “It’s the most gorgeous hydrangea, yet it is undemanding. The lime-white blooms are blowsy, beautiful and at their best in shade.” She also loves penstemons, notably Garnet, White Bedder and the pearly mauve-pink Sour Grapes.

“I use them constantly because they’re semi-evergreen and they repeat-flower if you deadhead them from summer to early autumn.”

Designer James Aldridge plants two exotics repeatedly, both of which he claims are hardy in town gardens. “Aloe striatula looks fantastic through the year, either in a container or in the ground, where it looks especially good among grasses. Astelia chathamica Silver Spear has sword-like leaves but doesn’t have the harshness of a phormium. It’s tolerant, but the silver foliage is best in semi-shade.”

Hellebore hybridus

Hellebore hybridus are invaluable because they flower early in the year
The principal of the English Gardening School, Rosemary Alexander, loves irises. “In a sunny spot, irises provide a great vertical, spiky shape. Lavender-blue Jane Phillips has the best leaves and flower height, and flowers from late spring for quite a while.

“For shade, Hellebore hybridus are unbeatable in providing flowers early in the year and are so easy, provided you cut back the leaves in early December.”

London’s gardens need plants with good structure and scale, not fleeting flowers, says designer Declan Buckley. “Agapanthus africanus fits the bill because the foliage stays evergreen, it has good, strappy leaves and fantastic big blue flowers.”

He has traded box, which can get blight, for safer bet Euonymus japonicus Microphyllus, which has a similar leaf and can be clipped like box. “And if you leave it, it makes a nice little dome all on its own.” Pleached trees make great living screens and Buckley favours two. “You can now buy pleached holly as well as Magnifolia grandiflora, which is investment dressing but worth every penny.”

Richard Reynolds, London’s chief guerrilla gardener, depends on plants that thrive on neglect. His secret weapon: “Lavender! It ticks every box: it’s fragrant, tough, beautiful in bloom, easy to look after and looks good all year round.”
