Summer flowers that are magnificent bloomers

Summer is certainly the season when we’re always in the garden! The outdoors of the home must then be at its finest and share with us its most astounding blooms. Here is our own selection of the 10 best summer flowers to grow in a flower bed.

Summer flower shrubs

At the back of a flower bed, shrubs will always help create volume and provide nice backdrops for smaller plants. These round shrubs dress the bed with large leafage. They also pitch in with a splash of color in summer.

  • Blooming period: June to October
  • Flower color: round flower clusters that are blue in acidic soil, and pale pink when it’s alkaline
  • Exposure: part shade
  • Soil: rich, well-draining, acidic or neutral
  • Cherry on the top? blooms abundantly

Rose tree

  • Heart of a Anastasia Adamariat roseVariety: Rosa Anatasia® ‘Adamariat’
  • Blooming period: June to October
  • Flower color: white urn-shaped roses with a yellow heart
  • Exposure: sun

Perennials that bloom in Summer

Perennials are the staple of most flower beds. Since they stay put, they bloom again and again every year in Summer.


  • Sage Mainacht growing alongside a roadVariety: Salvia nemorosa ‘Mainacht’
  • Blooming period: from May to September
  • Flower color: blue-violet flower panicles

Caring for honeybees and other pollinators is especially important in Summer: June and July are called the “pollen dip” because not many flowers open up in this time span. Pollinators are grateful to find lots of help from us gardeners!

Summer-blooming climbing vines

Is your flower bed set up against a wall or fence? Go ahead and cover it with climbing vines! Though they only take up very little ground space, they’ll completely cover the wall and hide it with flowers.
