12 Stunning Annual Flowers for Your Garden

Ready to add a blast of season-long color to your garden? Here are twelve reliable, beautiful, and easy-to-grow annuals that will bring you joy from spring until frost

.

1. Petunia

Petunias are the undisputed champions of the annual world. They are incredibly versatile, easy to grow, and offer a seemingly endless variety of colors, patterns, and sizes, from tiny single blooms to huge, ruffled doubles.

• Why You’ll Love Them: Petunias are prolific bloomers. With just a little care, they will produce a torrent of flowers all summer long. They are perfect for hanging baskets, window boxes, containers, and as a groundcover in garden beds.
• Growing Tips: Plant petunias in a spot that receives at least six hours of full sun each day. They thrive in well-drained soil and benefit from regular feeding with a balanced fertilizer. To keep them looking their best, “deadhead” the spent flowers by pinching off the old bloom and the little seed pod behind it.
• Varieties to Try: Look for ‘Wave’ petunias for a vigorous trailing habit perfect for hanging baskets, or ‘Supertunia’ varieties, which are bred to be self-cleaning (no deadheading required!) and incredibly weather-tolerant.

This is a must-have annual flower for anyone who wants a massive impact of color with minimal fuss.

2. Marigold (Tagetes)

Marigolds are like little bursts of sunshine in the garden. Known for their cheerful pom-pom-like flowers in shades of yellow, orange, and deep red, they are one of the most reliable and easy-to-grow annual flowers available.

• Why You’ll Love Them: Beyond their bright, happy blooms, marigolds are famous for their pest-repelling properties. The scent of French marigolds is known to deter nematodes in the soil and other garden pests, making them a fantastic companion plant for vegetable gardens.
• Growing Tips: Marigolds are incredibly low-maintenance. They thrive in full sun and can tolerate a wide range of soil conditions, as long as the soil isn’t constantly soggy. They bloom profusely with very little extra care, though deadheading will encourage even more flowers.
• Varieties to Try: ‘French Marigolds’ (Tagetes patula) are compact and bushy, perfect for edging beds. ‘African Marigolds’ (Tagetes erecta) are much taller and produce huge, globe-like blooms that are excellent for cutting.

For a dependable, pest-fighting, and brilliantly colored annual, marigolds are a top choice.

3. Zinnia

If you want to create a cutting garden, zinnias are an absolute must. These delightful annual flowers produce armloads of long-stemmed, daisy-like blooms in every color of the rainbow except blue. They are incredibly easy to grow directly from seed.

• Why You’ll Love Them: Zinnias are a pollinator paradise. Bees and butterflies flock to their open-faced blooms. They are fast-growing and come in a huge range of sizes, from dwarf varieties perfect for containers to towering four-foot-tall giants that create a stunning backdrop.
• Growing Tips: Zinnias love heat and full sun. Plant seeds directly in the garden after the last frost date. They prefer well-drained soil and good air circulation to prevent powdery mildew, so give them plenty of space. The more you cut them for bouquets, the more they will bloom.
• Varieties to Try: The ‘Benary’s Giant’ series is a favorite of flower farmers for its huge blooms on long, sturdy stems. The ‘Zahara’ series is known for its excellent disease resistance and compact, mounding habit.

Zinnias are the gift that keeps on giving, providing endless bouquets and attracting beautiful wildlife to your garden.

4. Geranium (Pelargonium)

The classic geranium is a staple of container gardens and window boxes for good reason. With their distinctive scalloped leaves and bold clusters of flowers, they provide a classic, timeless look and are incredibly heat and drought-tolerant.

• Why You’ll Love Them: Geraniums are tough. They can handle hot, sunny conditions that would make other annual flowers wilt. They have a bold, architectural presence and their fuzzy leaves often have a pleasant, spicy scent when touched.
• Growing Tips: Plant geraniums in full sun and well-drained soil. They do not like to have “wet feet,” so allow the soil to dry out slightly between waterings. Feed them regularly with a fertilizer formulated for blooming plants to keep the flower show going strong. Deadhead the spent flower clusters by snapping the stem off at its base.
• Varieties to Try: ‘Zonal Geraniums’ are the classic upright type perfect for pots. ‘Ivy Geraniums’ have a trailing habit and are stunning in hanging baskets. ‘Scented Geraniums’ have less showy flowers but have wonderfully fragrant leaves in scents like rose, lemon, and mint.

For a bold, reliable, and classic annual flower, geraniums are a perfect choice.

5. Impatiens

• Why You’ll Love Them: Impatiens provide a massive pop of reliable color in low-light areas. They can transform a dark, forgotten corner of the garden into a beautiful focal point. They are incredibly easy to care for as long as their basic needs are met.
• Growing Tips: The most important thing for impatiens is shade and water. They thrive in part to full shade and need consistently moist soil. If they wilt, a good drink of water will usually have them perking back up within the hour.
• Important Note: Traditional impatiens (Impatiens walleriana) are susceptible to downy mildew. For a more disease-resistant option, look for ‘New Guinea Impatiens’ or the ‘Beacon’ series of Impatiens walleriana, which have been bred for high resistance to the disease.

Impatiens are the go-to annual flower for brightening up the shady spots in your yard.

6. Cosmos

Cosmos are the embodiment of airy, whimsical charm. These tall, graceful annual flowers have delicate, fern-like foliage and simple, daisy-like blooms that dance on slender stems. They bring a sense of movement and wildness to the garden.

• Why You’ll Love Them: Cosmos are incredibly easy to grow from seed and will often self-sow for the following year. They are beloved by pollinators and are wonderful as a cut flower, adding a delicate, romantic touch to bouquets.
• Growing Tips: Cosmos actually prefer poor soil and can become leggy with fewer blooms if the soil is too rich. Plant them in full sun after all danger of frost has passed. They are quite drought-tolerant once established and don’t require much care at all. Taller varieties may need staking to prevent them from flopping over in wind or rain.
• Varieties to Try: ‘Sensation’ is a classic, tall mix of pink, white, and magenta blooms. ‘Seashells’ has unique, fluted petals that look like little trumpets. ‘Cosmic Orange’ is a shorter variety with brilliant, semi-double orange flowers.

For a touch of wildflower grace and effortless beauty, cosmos are a perfect choice.

7. Begonia

Begonias are a diverse group of annual flowers, but the most popular for garden use are wax begonias. These shade-tolerant workhorses form neat mounds of waxy green or bronze leaves and are covered in small, delicate flowers all season long.

• Why You’ll Love Them: Begonias are incredibly reliable and uniform. They are perfect for creating neat edges, formal bedding designs, or for filling in shady containers. They provide continuous color from spring until frost with almost no maintenance required.
• Growing Tips: Wax begonias thrive in part shade but can also tolerate full sun in milder climates if they are kept well-watered. They prefer consistently moist, well-drained soil. They are self-cleaning, so no deadheading is necessary.
• Other Types: Tuberous begonias produce huge, spectacular, rose-like flowers and are stunning in hanging baskets in the shade. Angel wing begonias are grown for their beautiful, spotted, wing-shaped leaves as much as for their delicate flowers.

For a neat, reliable, and long-blooming annual for sun or shade, begonias are a fantastic option.

8. Salvia

If you want to add a vertical element to your garden beds and containers, annual salvia is an excellent choice. These plants produce tall, elegant spires of small, densely packed flowers that are magnets for hummingbirds and butterflies.

• Why You’ll Love Them: Salvia adds a beautiful “spiller” or “thriller” element to container designs, providing height and a strong vertical line. They are very heat and drought-tolerant once established and bloom continuously throughout the summer.
• Growing Tips: Plant salvia in full sun in well-drained soil. While they are drought-tolerant, they will bloom more profusely with consistent moisture. Cutting off the main flower spike after it fades will encourage the plant to send up new side shoots with more flowers.
• Varieties to Try: ‘Victoria Blue’ is a classic with deep, indigo-blue flower spikes. ‘Salvia splendens’, also known as scarlet sage, comes in brilliant shades of red. ‘Mystic Spires Blue’ is a popular, award-winning variety known for its long bloom time and robust nature.

Salvia is an invaluable annual flower for adding structure, height, and pollinator appeal to your garden.

9. Sweet Alyssum (Lobularia maritima)

For a low-growing, fragrant, and delicate-looking groundcover, sweet alyssum is unbeatable. This annual flower forms a trailing mat of tiny, honey-scented flowers that spill beautifully over the edges of pots and pathways.

• Why You’ll Love Them: The honey-like fragrance of sweet alyssum is intoxicating on a warm summer day. It’s a fantastic “spiller” for containers and hanging baskets, softening the edges and creating a full, lush look. It also attracts beneficial insects like hoverflies.
• Growing Tips: Sweet alyssum prefers full sun to light shade and well-drained soil. It may stop blooming during the intense heat of mid-summer. If this happens, give it a light “haircut” by shearing it back by about a third, and it will flush out with new growth and flowers as the weather cools slightly.
• Varieties to Try: Classic sweet alyssum is white, but you can also find it in beautiful shades of purple and pink. Look for modern varieties that are bred to be more heat-tolerant.

Sweet alyssum is the perfect delicate and fragrant annual to weave throughout your garden.

10. Sunflower (Helianthus annuus)

Nothing says “summer” quite like a towering sunflower. While we often think of them as giant, single-stalked flowers, there is a huge world of annual sunflowers, including many multi-branching varieties that are perfect for creating a season-long display.

• Why You’ll Love Them: Sunflowers are the definition of cheerful. They are incredibly easy to grow from seed, making them a fantastic project for gardening with children. The seeds are also a valuable food source for birds in the fall.
• Growing Tips: Sunflowers need full sun, and lots of it. Plant seeds directly in the ground after the last frost. They are not picky about soil but will be sturdier in soil that isn’t too rich. Taller varieties will likely need staking to protect them from wind.
• Varieties to Try: For cutting, look for multi-branching varieties like ‘ProCut’ series or ‘Sunrich’ series. For something different, try ‘Teddy Bear’, a short, fluffy, pom-pom-like sunflower, or ‘Strawberry Blonde’, which has beautiful multi-toned petals.

Growing annual sunflowers is a joyful experience that brings a smile to everyone’s face.

11. Pansy & Viola

Pansies and violas are the cheerful faces of the cool seasons. These hardy annual flowers are the first to bloom in the spring and the last to quit in the fall, providing invaluable color when most other plants are dormant.

• Why You’ll Love Them: Their sweet, often “whiskered” faces are incredibly charming. They can tolerate light frosts, making them perfect for early spring and autumn containers. Many varieties also have a light, sweet fragrance. Bonus: the flowers are edible and look beautiful scattered on salads or desserts.
• Growing Tips: Pansies and violas thrive in the cool weather of spring and fall. Plant them in full sun to part shade in moist, well-drained soil. They will typically stop blooming when the intense heat of summer arrives. In many climates, you can plant a new batch in late summer for a beautiful fall display.
• What’s the Difference?: Generally, pansies have larger flowers with four petals pointing up and one pointing down. Violas (also called Johnny-jump-ups) have smaller but more numerous flowers.

These cool-weather champions are essential for extending the season of color in your garden.

12. Snapdragon (Antirrhinum)

Snapdragons add a wonderful vertical element and a touch of playful nostalgia to the garden. Children love pinching the sides of the flowers to make the “dragon’s mouth” open and close. They come in a huge array of colors and are fantastic cut flowers.

• Why You’ll Love Them: Snapdragons provide a beautiful spire-like shape that contrasts wonderfully with mounding annuals like petunias. They are a favorite of bumblebees, who are strong enough to push their way into the flowers to reach the nectar.
• Growing Tips: Snapdragons are another cool-season annual. They perform best in the milder temperatures of spring and fall and may slow down their blooming in the summer heat. Plant them in full sun in rich, well-drained soil. Deadheading the spent flower spikes will encourage more blooms.
• Varieties to Try: Snapdragons are often sold by height: dwarf, intermediate, and tall. The ‘Rocket’ series produces very tall spikes perfect for the back of the border and for cutting. The ‘Snapshot’ series is a dwarf variety ideal for containers and the front of beds.

Snapdragons bring height, color, and a touch of playful fun to any annual garden.
