Purple flowers are some of the most eye-catching blooms. In a sea of green grass, plants, and bushes, a pop of purple color evokes a feeling of serenity and magic.
But what variety should you pick? We’ll answer that question in this article.
Which Purple Flower Should You Plant?
Landscaping with purple flowers will vary based on the hardiness zone you live in within the United States.
Some tropical varieties are not well-suited for colder regions, and that require rainy conditions won’t thrive in the more arid parts of the country. For this reason, we’ve included the preferred climate zone for each flower.
In our list, you’ll find a variety of both perennial and annual deep purple to light purple flowers with blooms that range from tiny and delicate to big and bold.
Some have fragrant flowers that make them even more enjoyable to plant near your home. We’ve listed which plants are annual, perennial, or both.
Annual and Perennial Flowers
Before deciding what type of purple flowers to buy, you’ll need to know the difference between annual and perennial flowers. But don’t worry—we’ve highlighted each type for you.
These plants produce purple flowers during a single growing season. They will put on a show of pretty purple blooms and die at the end of the growing season.
Many of the purple flowers listed below are also available in a variety of other colors. This is important to know so you aren’t surprised when these flowers only stick around for one season.
These plants and bushes with purple flowers will come back year after year. If you live in an area that experiences cold winters, the vegetation of the plant may die and reappear in the spring or early summer.
In more temperate climates, perennials may not die back but may experience a short period of limited growth instead.
Note: Some types of flowering plants can be toxic to animals, adults, and/or children when ingested or touched. When this information is available, we have noted it with an asterisk, but please take care to research the possible toxicity of any plant you’re considering planting around your home.
