A symbol of royalty and elegance, purple is a favorite flower color that does a great job in enhancing a garden’s palette. When Pantone declared ultra violet, which is another variation of purple, as the Color of the Year in 2018, it described the shade as one that exhibits originality and ingenuity. While it may not be a popular choice when deciding on interior design or picking a wardrobe outfit, the color purple plays a key role in landscaping and gardening. It can anchor bright colors and is perfect for adding contrasting elements to your garden setting. Hence, there is no wonder why purple is one of the first things that come to mind when deciding on your garden’s color combinations.
There is a wide range of purple shades in which flowers bloom, but the mixture of blue and red is often associated with a calm ambiance and is used to create a relaxing mood. Purple flowers where blue is more dominant often creates a soothing effect and promotes spiritual calmness. In contrast, purple flowers leaning toward red are seen as more energetic. These different combinations yield an array of shade variations that are sure to add depth to your outdoor space. From dark violet, to soft purple, to lavender, the choices are far and wide depending on the shade and tone.
In this article, we identified some of the most popular purple flowers and categorized them based on their shape, shade, height, growing cycle and other characteristics.

You can also consider growing Hesperis Matrionalis, or more commonly known as Sweet Rocket. This biennial plant produces blooms in white and purple, and has a lovely fragrance in the evening.

If you are looking to create a meditation garden, then consider bushes with purple flowers in your landscape.
