Blue Flowers That Bloom in August

The summer brings bursts of colours from all types of flowers. Blue flowers add a nice splash of colour to any garden and provide a nice contrast to the typical flower colours of red, pink, and orange. During August, a number of blue flowers are in full bloom that are sure to enhance your summer garden.


The bellflower plant is a dense mounded perennial. It has light blue cup-shaped flowers on thin stems. This plant blooms between July and September. It flourishes in well-drained soil and full sun to partial shade. You must keep bellflowers watered well in the summer, and fertilising regularly will ensure a vivid display of blue flowers. Bellflowers attract hummingbirds.


The larkspur plant blooms with a mass of blue flowers. It prefers moist, well-drained soil. These plants grow tall, so it is best to support the stalks with a stake or plant ring. Larkspur does best in full sun to partial shade and fertilising it will elicit more hardy blooms. It is important to treat the plants to resist pests such as snails, slugs, spider mites and cutworms because these pests will ruin the flower. This flower also makes a good cut flower and dries well. Finally, if you are looking to attract birds, add this blue flower to your garden.

Globe Thistle

The globe thistle blooms steel-blue round-shaped flowers. This plant provides a stark contrast to the typical summer garden flowers. It grows 3 to 4 feet tall and prefers full sun. Although moist soil is preferable for this plant, it can tolerate drought conditions if need be. The globe thistle also tolerates disease and insects very well. These flowers are butterfly-attracting, so include them in your butterfly garden. If you want to bring a piece of your garden inside, this plant makes a good cut flower either fresh or dried.

Balloon Flower

With the balloon flower, the name speaks for itself. The violet-blue flowers blow up like balloons and open to form a bell shape. These plants need a slightly acidic, moist sandy or loamy soil to flourish and full sun to partial shade is the best light for them. The balloon flower requires little maintenance. Since they are easy to grow, they are perfect in a rock garden or as colourful ground cover.
