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.

Hydrangea

  • 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

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

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