These are the best annual flowers for full sun pots and beds that can be placed in both front yards and backyards. Annual flowers are a fantastic way to bring vibrant color and life to gardens, patios, and landscapes.
Best Full Sun Annual Flowers
Unlike perennials, which return year after year, annuals complete their life cycle in a single growing season. This makes them perfect for gardeners like me who love experimenting with different floral arrangements each year.
Choosing the right flowers for full-sun areas is crucial, as some varieties thrive in bright, warm conditions while others may wither under intense sunlight.
If you’re looking for stunning flowers that flourish in full sun, here are 15 of my best annuals for pots and beds.
Marigold
Marigolds are one of the most popular and reliable annual flowers for sunny locations. Their bright orange, yellow, and red blooms add a cheerful touch to any garden.
Marigolds thrive in full sun and require well-draining soil. They are also known for their pest-repelling properties, making them excellent companion plants for vegetables.
I also recommend deadheading spent blooms, which encourage continuous flowering throughout the season.
Petunia
Petunias are a staple in summer gardens due to their abundant blooms and wide range of colors.
These low-maintenance flowers grow well in beds, hanging baskets, and containers. Petunias prefer full sun and regular watering but can tolerate short dry spells.
Deadheading helps maintain Petunia’s vibrant display, ensuring flowers throughout the season.
Zinnia
Zinnias are easy-to-grow flowers that produce bright, daisy-like blooms in various colors, including pink, red, orange, yellow, and white.
They are heat- and drought-tolerant, making them ideal for full-sun areas. Zinnias attract butterflies and pollinators, adding extra beauty and biodiversity to your garden.
They grow best in well-draining soil and benefit from regular deadheading. Zinnias are easy flowers to grow even for beginners.
Lantana
Lantana is a heat-loving plant that produces clusters of tiny, multicolored flowers. It is a favorite among hummingbirds and butterflies.
Lantana thrives in dry, sunny conditions and requires minimal maintenance. Though it is an annual in colder climates, it can become a perennial in warmer regions. Check out this post on how to grow lantana flowers in pots.
Verbena
Verbena is known for its trailing habit and long-lasting blooms, making it perfect for borders, hanging baskets, and containers.
It produces flowers in shades of purple, pink, red, and white. Verbena thrives in full sun, tolerates drought well, and requires occasional deadheading to encourage continuous flowering.
Portulaca
Also known as moss rose, portulaca is an exceptionally drought-tolerant annual with succulent-like leaves and bright, delicate flowers.
It blooms in a variety of shades, including pink, red, yellow, orange, and white. Portulaca grows well in poor soil and thrives in hot, dry conditions, making it an excellent choice for full-sun areas.
Celosia
Celosia is an eye-catching annual known for its unique, feathery, or cockscomb-shaped blooms in bold shades of red, orange, pink, and yellow.
This plant thrives in full sun and warm temperatures, making it perfect for summer gardens. Celosia is relatively low-maintenance and requires minimal watering once established.
Salvia
Salvia produces striking spikes of red, purple, blue, or white flowers that attract pollinators like bees and hummingbirds.
It prefers well-drained soil and full sun, though it can tolerate partial shade. Regular deadheading encourages continuous blooming throughout the season.
Cosmos
Cosmos are delicate, daisy-like flowers that bloom profusely in hot, sunny conditions. They are easy to grow and tolerate poor soil, making them a great choice for beginner gardeners.
Cosmos are self-seeding, meaning they may return the following season if allowed to drop seeds. If you don’t want them to self-seed, cut them before they produce seeds. Check out this complete guide to growing cosmos flowers
Gazania
Gazania, also known as the treasure flower, features striking, daisy-like blooms in shades of yellow, orange, and pink. It thrives in full sun and dry conditions, making it an excellent choice for drought-prone areas.
Gazania flowers open during the day and close at night, adding an interesting dynamic to garden displays.

Sunflowers thrive in full sun and well-drained soil. They are easy to grow and attract bees and birds. Check out this complete growing and care guide for sunflower including best varieties.

Vinca, also known as Madagascar periwinkle, is a tough, drought-tolerant annual that produces glossy green foliage and bright, star-shaped flowers.
It blooms continuously throughout the season and is an excellent alternative to impatiens for sunny locations. Check out this complete growing and care guide for vinca.
