Garden design and maintenance

These 7 bushes bloom all summer long and delight the eye!

In addition to perennials and ground cover, flowering shrubs are an important element of a diverse and attractive garden design. Not only do they give shape and structure to the landscape, they also add color to the garden and attract butterflies and other pollinators. Here we introduce you to the most beautiful shrubs that bloom splendidly all summer long and delight plant lovers and bees.

Buddleia / butterfly bush: flowering time from July to October

The Buddleia is a long-flowering shrub

The butterfly bush (Buddleia davidii) is a summer flowering shrub with an upright, loosely overhanging habit and impressive flowers, but it has a mixed reputation. It is easy to care for and produces showy flower spikes all summer long. There are many varieties of Buddleia in many flower colors, including purple, pink, yellow, white, and multicolored. And as the name suggests, this shrub is known as a magnet for butterflies. Red-flowered butterfly bushes even attract hummingbirds in America.

Botanical name: Buddleia davidii

Location: sun to partial shade

Height: varies depending on the variety

Butterfly bushes are cultivated to suit many different gardening preferences. Some can grow up to 4 meters tall and form very large flower spikes, while others are relatively small. Butterfly lilac was first brought to England from Asia in 1774 by the botanist Adam Buddle (after whom the plant was named).

But while the butterfly bush is admired by many for its brightly colored flowers and long flowering period, it has an equally large number of opponents. It is considered an invasive plant in many areas of the United States – one that does not naturally grow in a particular region, but is so widespread that it is displacing native plants. Many plant experts warn that invasive plants are problematic because they can alter ecosystems and damage existing flora and fauna. Although not invasive everywhere, the butterfly lilac has gotten a bad rap. Several US states have now classified it as a harmful weed.

Buddleia is a shrub that blooms in summer

Butterfly bush should be planted with caution and only when you are ready to remove the flower heads in time to avoid the seeds from spreading. While there are many popular Buddleia varieties, including ‘Black Night’ (Flower color: dark purple) and Pink Delight (Flower color: pink), but newer, less vigorous varieties are enjoying increasing popularity. For example:

  • Buddleia x ‘Blue Chip’ is a compact variety, 90 to 180 cm high.
  • Buddleia ‘Miss Violet’ is another free-flowering, compact variety that grows to 120 to 150 cm tall and wide.
  • Other hybrid strains that were bred to be seedless are ‘Asian Moon’, ‘Ice Chip’ and ‘Purple Haze’.

Hydrangeas: flowering from June to September

Hydrangeas (Hydrangea spp.) Have been popular garden plants for decades. Her flowers now come in a variety of colors, including bright blue, deep red, and light green. Some hydrangeas have large, spherical flowers, while others have smaller, flatter, more delicate flowers. The foliage also varies depending on the species. These versatile shrubs also thrive in less nutrient-rich locations such as sandy coastal soils and shady forests. To give hydrangea bushes time to develop a healthy root system before they bloom, it is best to plant them in autumn or early spring. Once planted, hydrangeas grow quickly, averaging 60 cm or more per year.

blue flowering shrub in summer

The beard flower (Caryopteris x clandonensis) looks like a perennial at first glance, but is in fact a subshrub because it is woody at the base. The plant originated in England in the 1930s from an accidental crossing of C. incana and C. mongholica and has since been bred into several popular varieties.

Botanical name: Caryopteris x clandonensis

Location: sun to partial shade

Height: 80 to 100 cm

The beard flower is a subshrub that blooms all summer

The beard flower is one of the most beautiful summer bloomers. Its fragrant, nectar-rich flowers are also very tempting to butterflies, bees, and other beneficial insects. The compact growth and the silver-gray leaf color make the beard flower a good choice even for a small garden. The varieties with the longest flowering time are ‘Ferndown’, ‘Blauer Spatz®’ and ‘Pink Perfection’.

Ideally, the plant should be planted in spring or autumn, provided that your area doesn’t get too cold. Clandonensis hybrids typically grow between 45 and 75 cm per year. Once established, the garden plant requires very little water. Just make sure that beard flowers are only partially hardy.
