8 Purple Flowers to Grow in Florida

Purple flowers add an elegant, unique feel to a garden. Which ones should you consider growing in Florda?

Purple is an infrequent color in nature, making purple flowering plants all the more desirable in your garden. Because of its rare occurrence, the color purple was once associated with royalty because the dye needed to create purple clothing was expensive, and only the wealthy or ruling classes could afford it. 

The effects of the color on someone’s mood vary by shade. It can have a calming and energizing influence on our bodies, increasing concentration and understanding. It can also promote creativity by stimulating our senses and fostering the stillness needed for intuitive, insightful observations. 

Florida has a different climate compared to most other states. The state’s climate encourages tropical plants, and gardeners must struggle with extreme humidity. In this post, I’ll show you some incredible purple flowering plants that can handle the climates in zones 8 to 10 while remaining attractive.

1. Jacaranda 

The jacaranda is a floral treasure of Central and South Florida and is a delicate evergreen tree that spreads abundantly. Its fern-like leaves provide a soft, mottled shade that is great for patios. The trumpet-shaped flowers, which range in color from light to deep purple, do best in direct sunlight. They require sandy, well-drained soils and continuous water while they are growing.

2. Tall Garden Phlox

Tall garden phlox is a must-have for every Florida summer yard. These perennials have purple flower clumps that bloom in the middle of summer and last until late in the fall. The flowers range in size from 25 to 35 inches long and come in various colors.

Tall garden phlox flourishes in zones three to eight, meaning it will thrive in Florida. You can see the purplish-red blossoms after they’ve fully matured. Plant it in areas with full exposure to the sun and fertile loamy soils for excellent growth.

3. King’s Mantle

Thunbergia erecta (King’s Mantle) is a 48-inch-tall upright shrub. The shoots have a quadrangular form and a slender wing at each angle. The leaves are ovate-elliptic and oriented oppositely. Occasionally, the leaf margin is whole or wavy, with a large triangular tooth above the center.

The two-inch-long evergreen oval leaves form a lovely, easy-to-manage hedge. The foliage is complemented with one-and-a-quarter-inch-long royal purple to blue flowers with yellow throats that can be planted alone or in groups.

Because king’s mantle is a medium-sized shrub, it can be kept at five to six feet without being pruned if planted in the proper location. King’s mantle planted on 36-inch centers can be used to line porches or near foundations.

4. Hibiscus

With their large, beautiful flowers that bloom all year, Hibiscus plants highlight Florida’s tropical charm. Blooms come in flare and bell shapes. They are available in various colors and shapes, including dual, single, serrated, and plain. While tropical hibiscus comes in multiple colors, such as pink, white, and orange, a purple cultivar is also available.

Hibiscus is often grown as a shrub, but some varieties can reach 15 feet. It enjoys full to partial sunlight and rich, well-drained soil. They are beautiful when fully developed and can be utilized as hedges or shadows.

5. Mexican Heather

Mexican heather flowers are available all year. They’re hardy in zones 8 to 10 and would make an excellent addition to any Florida garden. Some have white or crimson blooms against lush green foliage, while others produce little purple blossoms.

Mexican heather, when completely developed, creates a dense, flowering shrub that grows to be about 12 inches tall. They make great borders or edging on stroll routes, can be grown in pots, and their lovely scents attract butterflies. Whether or not you pot it, ensure that it receives adequate sunlight and is in well-drained soil.

6. Reticulated Iris

Reticulated iris is easy to grow if you have good drainage and somewhat moist soil. If a bulb fertilizer is utilized, the reticulated iris will thrive in zones 5 to 9. Florida gardeners can use this plant in their gardens. For zones 8 and up, select the harmony cultivar.

Regardless of cultivar, reticulated iris produces purplish-blue flowers that thrive in light shade. On the other hand, the blossoms appear tri-colored, with a deep purple tint and yellow-blue white tinge. Lastly, the shorter varieties only grow to 6 inches tall.

7. Salvia

Salvia is a perennial with bright purple flowers that bloom throughout the summer. They prefer hot weather and intense sunlight, making them an excellent plant for cultivating in Florida. Salvia grows up to 18-inches tall, and its square stem identifies it as a member of the mint family.

They can endure drought but require good drainage and sunlight to thrive.

8. Queen’s Wreath

Queen’s wreath is a tropical vine with densely packed flowers that, from a distance, resemble a cluster of grapes. The pale blue or violet flowers are small and eventually fall to the ground, leaving behind the calyces. A calyx is the base of a flower and is usually green. However, on queen’s wreath features purple calyces equally as beautiful as the true flower petals.

The queen’s wreath blooms several times a year, notably between February and June. This plant thrives in full sun but can also take light shade. They are also resistant to drought, wind, and salt, making them ideal for coastal gardeners. Queen’s wreath requires constant watering to get established, and young, small plants should be protected from frost.
