10 BEST PURPLE FLOWERING SHRUBS

1. Lavender (Lavendula)

Lavender is a fragrant perennial shrub that flowers from late spring through to late summer.

English and French Lavender are two of the most popular types of Lavender but there are more than 450 different varieties available. [1]

Lavender grows best in full sun but you can also plant it in a container and place it in front of a sunny window for a beautifully fragrant houseplant.

2. Hydrangea (Hydrangea macrophylla)

Hydrangeas are easy to grow perennial shrubs with flowers in a variety of colors including purple, pink, blue and white.

If your soil is acidic with a pH lower than 5.5, you’re more likely to get blue or purple flowers.

Soil that is more alkaline will produce pink flowers.

Hydrangeas grow best in a position with morning sun and afternoon shade.

Bougainvilleas are popular climbing plants but they can also be trimmed into round bush shape.

The brightly colored flowers are actually modified leaves called bracts, and they can be purple, pink, red, yellow or orange.

Bougainvilleas are fast-growing, heat loving and drought resistant. They will flower best in full sun.

  1. Purple is such a powerful color and I love seeing purple flowers. I am fascinated with everything lavender but also love the beauty of bougainvilleas.

  2. We have several different varieties of hydrangeas in our yard and the soil plays a major factor in the color of the flowers. Where I live the soil is a mix of clay and sand so we don’t always get that bright purple. I’m also a big fan of rhododendrons. We’ve planted the butterfly bush before as well and boy did it spread. I still have shoots that pop up now and then.

  3. This is a great article for anyone who wants to see more purple in their garden. Even if you don’t garden yourself, you still learn quite a bit about the different varieties of flowers that are purple.
