Shrubs are often described as the backbone of a garden, and can offer not only beautiful flowers but height and structure, foliage and berries.

Flowering shrubs are often excellent for attracting bees, butterflies and other pollinators, and many have the added bonus of deliciously scented flowers. They can also provide much needed shelter, food and habitat for wildlife – birds are more likely to visit bird feeders if they have protective shrubs to dart in and out of.

Read about the best shrubs for birds.

Some flowering shrubs have evergreen foliage and look good all year round; others are deciduous, and may offer beautiful foliage in autumn before it falls. Deciduous shrubs can be underplanted with spring bulbs such as crocus or spring flowers such as primulas, which flower before shrubs come into leaf.

You can grow flowering shrubs as focal points in a front garden or lawn or grow them in a mixed border of shrubs, perennials and annuals.

There are flowering shrubs to suit every garden. Choose carefully and you can enjoy shrubs in flower in every season of the year.

Are there any shrubs that flower all year?

There are no shrubs that flower continuously all year round. However, some shrubs do flower for a very long time, straddling two seasons, such as abelia, which starts flowering in summer and continues well into autumn. With a little planning you can plant flowering shrubs to add interest in your garden for 12 months of the year.

The ‘flowers’ of these bushy shrubs are actually brightly coloured, winged fruits that smother the plant in autumn (spindles actually produce insignificant flowers in late spring or early summer). These fruits split to reveal seeds in contrasting colours – usually pink casings with metallic-blue or orange seeds. This coupled with stunning autumn foliage makes the plant an arresting sight. Euonymus europaeus ‘Red Cascade’ is one of the best cultivars. Euonymus are tough plants that are happy in most soils and conditions.

Flowers: Fruits from September/October/November/December
