To help you choose your shrubs depending on their blooming season, Nature-and-Garden recommends this selection of the most beautiful flowering shrubs for each season. It’s the best way to have a flowered garden all year round…

Flowered shrubs all year round!

Whether for a hedge or for a shrub bed, one good piece of advice to heed is to choose different blooming seasons for each of your shrubs, to keep your garden alive all year round.

You’ll love admiring those flowers from the end of winter up to the first frost spells.

Space each shrub to its mature width, not its size in the pot.

Nine flowering shrubs, season by season

The shrubs described below cover the whole year between them, from the depths of winter to the last of the autumn flowers. Use this table to pick one bloomer per season, then read the detail underneath.

Nine flowering shrubs, season by season
Shrub Flowering season Flowers and scent Best use
Winter honeysuckle (Lonicera fragrantissima) Early winter to late winter Very fragrant, often opening before the snow Part vine, part shrub; stands alone if pruned carefully
Yellow mimosa Early winter to late winter Yellow, lighter scent but definite up close Flowers shrug off sleet and ice
Forsythia Early spring to late spring Long sprigs lined thick with yellow blooms Bright, easy-care hedges
Soap bush Early spring to late spring Bright violet blue, thumb-size clusters Easy grower for a shrub bed
Lavender Early summer to late summer Heavenly scented, many species and varieties Choose non-invasive lavandin outside Europe
St John’s wort (Hypericum) Early summer to late summer Yellow flowers over deep emerald-green foliage Free-style hedge at a reasonable height
Myrtle Early summer to mid-autumn Pearly white Sandy, poor or dry ground; dwarf forms exist
Caryopteris (bluebeard) Early autumn to late autumn Deep violet, hectic-looking blooms Feeding bees and other pollinators

Mixing shrubs from each block of the table is what keeps a garden in flower from the end of winter to the first frosts.

Blooming of shrubs one season at a time

Winter-blooming shrubs

The most magnificent winter blooming shrubs include, for the three winter months of December, January, and February:

Among the first winter shrubs to open

Part vine and part shrub, in time this grows thick enough to stand on its own if you prune it carefully. The winter-blooming species is Lonicera fragrantissima.

Yellow mimosa is another great winter bloomer
Sleet and ice leave these winter flowers untouched

Typically, summer is when most of us have time to go around and savor the great outdoors. Plant these to have blooming shrubs in June, July and August!

Lavender is a magnificent option for summer blooms
A scented summer favourite with countless varieties

Advantages of planting shrubs that bloom in different seasons

To support your garden’s ecosystem, diversify your varieties, because each has different characteristics and this is important to ensure biodiversity. This is particularly important to pollinators if you want to save the bees, butterflies and other insects.

Sometimes after the Spring frenzy, they undergo a time of hardship even though the weather is warm. It’s called the “June pit” when insect colonies are in full swing but not many shrubs or flowers bloom. Planting summer and fall-blooming shrubs helps them meet their needs.

In winter, too, flowers are important. On warmer days, when bees leave the hive to evacuate their droppings, they also seize the chance to collect any pollen and nectar they can get hold of.
