6 Annual Flowers that Grow Best in Florida

Many homeowners plant annual flowers year-round to add an almost infinite variety of colors to the outdoor space. When placed in pots, hanging baskets, and containers, they add a splash of color to landscape beds and liven up a porch, deck, or patio. While annual flowering plants are fleeting, we still love them for their vivid, long-lasting blooms and the opportunity to refresh our gardens with new colors and varieties every year.

The key to enjoying these benefits is to know which ones to plant and when. Understanding the specific needs and optimal planting times for these flowers will ensure your garden flourishes with colorful blooms throughout the year.

What are Annual Flowers?

There are two types of flowering plants: annuals and perennials. Annual flowering plants usually complete a life cycle—from seed germination to the time they produce flowers—within a year or one growing season. Meanwhile, perennials can live for many years with proper maintenance. The main benefit of planting annual plants is that they bloom more flowers that usually last longer. This means annuals can stay in bloom for multiple seasons, while perennials usually only bloom for one. In Florida, annuals are categorized into cool-season and warm-season annuals:

Cool-Season Annual Flowering Plants in Florida

Cool-season annuals are planted in the fall and winter, relishing cooler temperatures. They grow best in spring or fall or areas with moderate summers.


Scientific Name: Petunia spp.

Planting Zone: USDA Zones 9-11

Petunias are a favorite in Florida gardens due to their bright, trumpet-shaped flowers in various colors, like pink, purple, red, white, and yellow. These South Florida annuals can be grown as tender perennials in USDA plant hardiness zones 9 to 11, requiring full sun and well-drained soil. Regular watering and removing dead flower heads can encourage further seasonal bloom.


Scientific Name: Viola tricolor var. hortensis

Planting Zone: USDA Zones 6-10

Pansies bring a cheerful burst of color to Florida gardens with their heart-shaped, overlapping petals in various colors, such as yellow, blue, purple, and white. These flowering plants prefer partial to full sun and rich, well-draining soil. Consistent moisture and pinching back spent blooms allow you to maintain their lush appearance and encourage new blooms.


Scientific Name: Antirrhinum majus

Planting Zone: USDA Zones 7-10

Snapdragons add vertical interest to gardens with their tall spikes of tubular flowers available in red, pink, yellow, and white. These winter annuals thrive in full sun to partial shade and require well-draining soil and regular watering. Taller varieties may require support to prevent flopping.

Warm-Season Annual Flowering Plants in Florida

On the other hand, warm-season or summer annuals are planted during the warmer months, providing seasonal color in spring and summer. However, some annuals can become perennials in warmer climates, like Florida, where the lack of a hard frost allows them to keep growing year-round.


Scientific Name: Tagetes spp.

Planting Zone: USDA Zones 2-11

Marigolds are known for their bright, pom-pom-like flowers in orange, yellow, and red. They come in several varieties suitable for plant hardiness zones 2-11, thriving in full sun and well-drained soil. Once established, they develop tolerance to drought, making them a low-maintenance option for warm-season gardens


Scientific Name: Zinnia elegans

Planting Zone: USDA Zones 3-10

These daisy-like flowers are available in stunning colors, including pink, red, orange, yellow, and white. Zinnias require full sun and well-drained soil conditions to prevent waterlogging that can result in mildew growth.


Scientific Name: Impatiens walleriana

Planting Zone: USDA Zones 10-11

Impatiens are a favorite for shady areas, delivering brightly colored flowers in pink, red, orange, purple, and white. These flowers prefer partial to full shade and need moist, well-drained soil. Regular watering is crucial, and it's important to avoid exposing them to hot, direct afternoon sun to prevent wilting. They add color to shaded areas or those with dappled sunlight.


How to Grow and Maintain Annual Flowers in Florida

Every plant requires a certain level of maintenance to ensure its successful development, which is particularly true for annual flowers in Florida. The unique climate, with its distinct wet and dry seasons, intense sun, and occasional frost in some regions, requires attention to detail. Besides the season, other considerations include sun exposure, shade, and specific soil conditions.

Site preparation is where the work begins. A nutrient-rich soil provides a strong foundation for annuals, whether you're planting them in a pot, flower bed, or directly into the soil. Ensuring the soil is well-aerated and weed-free will give your delicate plants the best start. To ensure growth, we recommend providing a slow-release fertilizer like NutriPod® at the time of planting. This type of fertilizer delivers a steady supply of nutrients for up to 45 days without the risks of nutrient leaching or over-fertilizing.

Although watering may seem simple, it is crucial to do it correctly. Balanced watering avoids the risks of too much or too little watering. Overwatering can lead to root rot, while underwatering can cause wilting and stunted growth. Aim for a consistent watering schedule that keeps the soil moist but not waterlogged.



By understanding the specific requirements and optimal planting times for cool-season and warm-season annuals, you can ensure your Florida garden is filled with vibrant and lasting blooms year-round. Whether you're looking to brighten up landscape beds or add color to your porch, deck, or patio, selecting the right annuals for each season will help you achieve a stunning and colorful outdoor space.
