Top 10 Evergreen Shrubs

Top 10 Evergreen Shrubs

Evergreen shrubs provide permanent structure in the garden and all-year-round interest. Some have beautiful flower displays or are highly scented in winter when little else is growing, and some have variegated or colourful foliage which is a perfect foil for summer perennials and a feature in itself during the winter. Grow evergreen shrubs as stand-alone specimens, as part of a mixed border or as hedging.
There are plenty of evergreen shrubs to choose from but if you need some inspiration take a look at our pick of top ten evergreen shrubs for an easy and reliable display.

1. Daphne

daphne
Daphne plants are well loved for their small but incredibly fragrant flowers which appear in winter and early spring, when little else in the garden is growing. There are both plain-leaved and variegated varieties available, such as Daphne odora ‘Aureomarginata’, which has a rounded compact habit and attractive glossy, yellow-edged leaves. Daphne is fairly slow-growing making it a superb small evergreen shrub for the garden. Grow Daphne in sunny or partially-shaded mixed borders, woodland gardens and rock gardens. Daphne laureola and Daphne pontica are excellent for difficult, heavily shaded areas of the garden.
box

2. Box

Box (Buxus) is a compact and versatile evergreen shrub. Box plants are superb for clipping into a small, formal hedge which can be used to edge vegetable or flower beds, or try creating your own elaborate box parterre! Being tolerant of deep shade, it’s great for awkward sunless spots or for growing beneath tall trees. Box can also be used for topiary, either in the ground or grown in patio containers. Grow box in a well-drained soil in partial or full shade. Keep the soil moist if growing box in full sun to prevent the leaves from scorching. Other similar shrubs which can be grown to the same effect include Lonicera nitida, Taxus baccata 'Semperaurea' or Ilex crenata.
fatsia

3. Fatsia

Fatsia japonica is a versatile shrub with large, glossy hand-shaped leaves borne on stout, upright stems. This exotic-looking shrub is surprisingly hardy and copes well with coastal conditions and tricky shady areas of the garden. Large stems of creamy white flowers, arranged in spherical umbels are produced in the autumn, which are attractive to bees and a great source of late season nectar. Fatsia plants are very architectural and can be grown in borders or large patio containers as an eye-catching feature.
lavender

4. Lavender

A well-loved shrub grown for its fragrant summer flowers and scented silver-green foliage. Flowering in shades of purple, lilac or pink, this hardy shrub is so versatile; from edging to hedging and borders to patio containers - every garden should have lavender! The flowers are highly attractive to bees and butterflies and thanks to their Mediterranean origins, lavender plants have good drought tolerance, coping well with light, sandy soils. Use the silvery foliage as a contrast to dark foliage plants and try cutting some lavender flowers for a vase indoors, or to sprinkle on top of cakes!
aucuba

5. Aucuba

One of the toughest shrubs out there! Aucubas are popular evergreen shrubs valued for their tolerance of full shade, dry soils, pollution and salty coastal conditions. Although plain-leaved varieties are available, the speckled yellow cultivars are the most popular and give rise to the common name ‘Spotted Laurel’. The leaves are generally quite large, to 20cm (8") long, leathery and glossy in appearance making them useful for achieving a tropical look in the garden. Female plants will produce bright red berries in autumn if a male pollination partner is planted nearby. Grow Aucuba as specimen plants, for hedges or in difficult heavily-shaded corners of the garden. They will even grow well in large patio containers making a fine contrast or foil to other foliage plants and flowers.
camellia

6. Camellia

A classic spring-flowering shrub originating from the woodlands of Asia. Camellias are popular for their glossy deep green foliage and abundance of large, showy flowers early in the year. Camellia flowers can be single or double and come in a wide range of colours from pink to red, through to yellow or white. Although naturally large shrubs, dwarf varieties are available and Camellias tolerate hard pruning well so can easily be controlled if outgrowing their allotted space. They are elegant shrubs, ideal for mixed planting schemes or as specimen shrubs in borders and woodland gardens where they will receive partial or dappled shade. They require an acid soil so if your soil is neutral or alkaline grow Camellias in large patio containers filled with a mixture of ericaceous compost and a soil-based compost such as John Innes No. 3.
euonymus

7. Euonymus

Cultivars of Euonymus fortunei are versatile, low-maintenance, evergreen shrubs with a multitude of uses and a tolerance of poor soils, coastal conditions and shade. Thanks to its prostrate habit these Euonymus plants can be grown as evergreen ground cover or trained to climb a wall - they tolerate north-facing walls well. They can also be grown as hedges or free standing shrubs in garden borders and patio containers. With a variety of foliage colours available from green to variegated white or gold, Euonymus fortunei cultivars are fantastic for adding winter colour to the garden.
mahonia

8. Mahonia

Mahonia plants have an architectural form and glossy, spiny leaves, similar to holly. They are valued for their late winter and spring flowers which are bright yellow and highly fragrant. Mahonia flowers are borne on long, elegant racemes or in clusters at the tips of branches, creating a distinctive and striking display when much of the garden is still dormant. They are also a fantastic early source of pollen and nectar for bees. Coping well with coastal conditions, clay soils and heavy shade Mahonia makes an unbeatable, low-maintenance addition to shrub borders and woodland gardens. Some species and cultivars have a low-growing habit and can be used as groundcover.
photinia

9. Photinia

Photinias are tough, versatile shrubs, the most popular variety being Photinia x fraseri ‘Red Robin’, whose glossy leaves are bright red when young, gradually changing to bronze-green through to deep green. Photinias light up shrub borders in the spring and make a good foil for summer-flowering plants. Grow Photinias in sunny borders, as specimen shrubs in large patio containers, or as hedging, for which Photinia x fraseri is ideal.
holly

10. Holly

A well-known evergreen shrub, with glossy, dark green leaves, which can be either spiny or smooth. Although best known for its classic dark green leaves and red berries at Christmas, there are many variegated forms of Holly which make outstanding specimen plants in the garden or planted as part of a mixed border. Holly plants also make a fantastic dense hedge, for which Ilex aquifolium and Ilex x altaclerensis are the best species to use. The spring flowers are highly attractive to bees and are followed by red or yellow berries on female holly bushes, if a male pollination partner is planted nearby. The berries are a good winter food source for birds. Tolerant of coastal conditions and partial shade, this tough shrub deserves a place in every garden.

Why to grow trees

Trees combat climate change
Excess carbon dioxide (CO2) caused by many factors is a building up in our atmosphere and contributing to climate change. Trees absorb CO2, removing and storing the carbon while releasing the oxygen back into the air. In one year, an acre of mature trees absorbs the amount of CO2 produced when you drive your car 26,000 miles.
Trees provide food
An apple tree can yield up to 15-20 bushels of fruit per year and can be planted on the tiniest urban lot. Aside from fruit for humans, trees provide food for birds and wildlife.
Trees provide wood
In suburban and rural areas,  trees can be selectively harvested for fuel and craft wood.
Trees increase property values
The beauty of a well-planted property and its surrounding street and neighborhood can raise property values by as much as 15 percent.
Trees heal
Studies have shown that patients with views of trees out their windows heal faster and with less complications. Children with ADHD show fewer symptoms when they have access to nature. Exposure to trees and nature aids concentration by reducing mental fatigue.
Trees conserve energy
Three trees placed strategically around a single-family home can cut summer air conditioning needs by up to 50 percent. By reducing the energy demand for cooling our houses, we reduce carbon dioxide and other pollution emissions from power plants.
Trees save water
Shade from trees slows water evaporation from thirsty lawns. Most newly planted trees need only fifteen gallons of water a week. As trees transpire, they increase atmospheric moisture.
Trees help prevent water pollution
Trees reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree. This prevents stormwater from carrying pollutants to the ocean. When mulched, trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.
Trees help prevent soil erosion
On hillsides or stream slopes, trees slow runoff and hold soil in place.
Trees clean the air
Trees absorb odors and pollutant gases (nitrogen oxides, ammonia, sulfur dioxide and ozone) and filter particulates out of the air by trapping them on their leaves and bark.
Trees provide oxygen
In one year an acre of mature trees can provide enough oxygen for 18 people.
Trees cool the streets and the city
Average temperatures in Los Angeles have risen 6°F in the last 50 years as tree coverage has declined and the number of heat-absorbing roads and buildings has increased.
Trees cool the city by up to 10°F, by shading our homes and streets, breaking up urban “heat islands” and releasing water vapor into the air through their leaves.
Trees shield children from ultra-violet rays
Skin cancer is the most common form of cancer in the United States. Trees reduce UV-B exposure by about 50 percent, thus providing protection to children on school campuses and playgrounds - where children spend hours outdoors.
Trees reduce violence
Neighborhoods and homes that are barren have shown to have a greater incidence of violence in and out of the home than their greener counterparts. Trees and landscaping help to reduce the level of fear.
Trees mark the seasons
Is it winter, spring, summer or fall? Look at the trees.
Trees create economic opportunities
Fruit harvested from community orchards can be sold, thus providing income. Small business opportunities in green waste management and landscaping arise when cities value mulching and its water-saving qualities. Vocational training for youth interested in green jobs is also a great way to develop economic opportunities from trees.
Trees are teachers and playmates
Whether as houses for children or creative and spiritual inspiration for adults, trees have provided the space for human retreat throughout the ages.
Trees bring diverse groups of people together
Tree plantings provide an opportunity for community involvement and empowerment that improves the quality of life in our neighborhoods. All cultures, ages, and genders have an important role to play at a tree planting or tree care event.
Trees add unity
Trees as landmarks can give a neighborhood a new identity and encourage civic pride.
Trees provide a canopy and habitat for wildlife
Sycamore and oak are among the many urban species that provide excellent urban homes for birds, bees, possums and squirrels.
Trees block things
Trees can mask concrete walls or parking lots, and unsightly views. They muffle sound from nearby streets and freeways, and create an eye-soothing canopy of green. Trees absorb dust and wind and reduce glare.
