Purple Flowering Shrubs (with Pictures) – Identification and Planting Guide

Purple flowering shrubs are excellent additions to your landscape to add beautiful colors. Shrubs with purple flowers can add hues of lilac, lavender, plum, violet, and mauve. In full bloom, the colorful purple bushes contrast with luscious green foliage, creating exciting color combinations. By planting perennial flowering bushes, you have flowers that come back year after year. With evergreen flowering shrubs, your garden can have color in your landscape throughout the year.

Growing purple flowering shrubs in your front or backyard can be straightforward. You should select flowering bushes suitable for your growing zone, hours of daily sunshine, and soil type. In addition, it’s always best to choose low-maintenance shrubs to cut down on gardening time. This way, you can enjoy purple flowers and delightful fragrances without spending a long time pruning, fertilizing, and watering the bushy plants.

Even if you don’t have a large yard to plant big flower bushes, many purple landscape plants are relatively compact and grow well in containers. For example, when grown in pots, dwarf purple flowering shrubs can decorate a patio, deck, entranceway, or container garden.

This article is a complete guide to the best purple landscape shrubs, bushes, and plants for your garden landscape. In addition, pictures of the purple flowering bushes will help find suitable plants to grow around your house.

How to Choose the Best Shrubs with Purple Flowers

Selecting the best flowering shrubs for your garden depends on several factors. The first factor is location. Flowering evergreen and perennial shrubs can grow as hedges, foundation plants, along borders, or at the back of a flower bed. It’s also good to consider the amount of sunlight or shade the plant gets.

One of the most critical factors to ensure flowering shrubs perform at their best is your temperature zone. Many perennial flowering plants thrive in USDA zones 5 through 9. So, you can grow rhododendrons, lilac, rose of Sharon, wisteria, and butterfly bushes in temperate climates. However, purple shrubs like fuchsias, bougainvillea, and golden dewdrops need warm temperatures to thrive outdoors.
