It Creates a Cheerful Mood: The psychological association with yellow is overwhelmingly positive. It evokes feelings of happiness, optimism, and energy. A garden filled with yellow annual flowers is a garden that makes you feel good.
It’s a Pollinator Magnet: Many bees and other beneficial insects are strongly attracted to the color yellow. By planting a variety of yellow blooms, you’re not just creating a beautiful space for yourself; you’re also creating a valuable food source for local pollinators.

15 Stunning Yellow Annual Flowers for a Sun-Kissed Garden

Ready to bring the sunshine to your garden? Here are 15 of the best yellow annual flowers, perfect for adding that golden touch to your landscape.

1. Marigold (Tagetes)

Marigolds are the quintessential cheerful yellow annual flower. These hardworking plants are incredibly easy to grow and will produce a profusion of bright, pom-pom-like blooms from spring until the first frost.

They come in every shade of yellow, from the palest primrose to deep, burnished gold.

As a bonus, their pungent scent is a well-known deterrent for garden pests like rabbits and nematodes.

Shades of Yellow: Pale lemon, bright canary, deep gold, and bicolor with orange or red.
Why You’ll Love It: They are incredibly low-maintenance, thrive in full sun, and serve as a natural pest repellent, making them a perfect companion in vegetable gardens.
Gardening Tip: For the biggest, most impressive blooms, amend your soil with good compost. Using a sturdy, comfortable trowel, like one from the {Fiskars 3-Piece Ergonomic Garden Tool Set}, makes digging and planting a pleasure rather than a chore.

2. Zinnia (Zinnia elegans)

If you want pure, unadulterated color, zinnias are a must. These sun-loving annuals come in a variety of forms, from simple, daisy-like petals to huge, dahlia-flowered heads.

Yellow varieties are particularly stunning, offering shades from soft butter to electric lemon. They are a favorite of butterflies, who will flock to your garden to feast on their nectar.

Shades of Yellow: Creamy white-yellow, soft butter, bright lemon, and vibrant gold.
Why You’ll Love It: They are one of the easiest flowers to grow from seed, they adore heat, and they make fantastic, long-lasting cut flowers for summer bouquets.
Gardening Tip: Starting zinnias from seed is incredibly rewarding. A high-quality seed packet, such as the {‘Canary Bird’ Zinnia Seeds by Burpee}, will produce tall plants with huge, brilliant yellow blooms perfect for a cutting garden.

3. Sunflower (Helianthus annuus)

No list of yellow annual flowers would be complete without the iconic sunflower. While we often think of the giant, towering varieties, there are many dwarf and branching types that are perfect for smaller gardens and even large containers.

From the classic golden yellow to pale, creamy yellows, sunflowers are the embodiment of summer.

Shades of Yellow: Pale ivory, lemon chiffon, classic sunflower gold, and deep orange-yellow.
Why You’ll Love It: They are dramatic, cheerful, and provide food for birds and pollinators. Their happy, sun-tracking faces are a joy to watch.
Gardening Tip: Sunflowers are heavy feeders and need support as they grow. When planting, mix a slow-release fertilizer like {Jobe’s Organics All-Purpose Granular Fertilizer} into the soil to provide a steady stream of nutrients for strong stems and big blooms.

4. Begonia (Begonia varieties)

While many begonias are for shade, tuberous begonias offer some of the most spectacular yellow blooms you can find, and many modern varieties can handle more sun.

The flowers are enormous, resembling lush, multi-petaled roses. The yellow varieties are particularly breathtaking, with colors ranging from soft, buttery yellow to vibrant, almost neon shades.

Shades of Yellow: Soft primrose, buttery yellow, and brilliant golden-yellow.
Why You’ll Love It: They provide incredibly showy, rose-like blooms. The ‘Nonstop’ series is famous for blooming profusely all season long.
Gardening Tip: These begonias grow from a tuber. To ensure they have the best drainage and nutrients in a pot, use a high-quality potting medium like {Black Gold All Purpose Potting Soil}, which is rich in organic matter.

5. Calibrachoa (Calibrachoa x hybrida)

Often called “Million Bells,” calibrachoa is a must-have for sunny hanging baskets and containers. These prolific bloomers look like miniature petunias and come in a vast array of colors, with yellow being one of the most popular.

The ‘Superbells Lemon Slice’ variety, with its pinwheel pattern of yellow and white, is a famous and fun example. They trail beautifully, creating a dense cascade of color.

Shades of Yellow: Pale lemon, bright canary yellow, deep gold, and fun bicolor patterns.
Why You’ll Love It: The sheer volume of flowers is incredible. They are self-cleaning (no deadheading) and perfect for creating a lush, overflowing look.
Gardening Tip: Calibrachoa is a heavy feeder. If the leaves start to look pale or yellow, it often indicates a need for fertilizer. A liquid feed with a product like {Miracle-Gro Water Soluble All Purpose Plant Food}, applied every two weeks, will keep them deep green and covered in blooms.

6. Bidens (Bidens ferulifolia)

Bidens is a cheerful, airy annual that is absolutely covered in small, star-shaped, golden-yellow flowers from spring until frost. It has fine, fern-like foliage and a spreading, slightly trailing habit that makes it a perfect “filler” and “spiller” in container arrangements. It’s tough, drought-tolerant, and a favorite of bees.

Shades of Yellow: Bright, golden-yellow.
Why You’ll Love It: It blooms nonstop, has a lovely fine texture, and mixes beautifully with other plants, filling in all the gaps with its sunny little flowers.
Gardening Tip: Bidens is not picky, but like any plant in a container, it appreciates good drainage and consistent watering. Using a lightweight, kink-free hose like the {Flexzilla Garden Hose} makes watering pots on a sunny patio quick and painless.

7. Portulaca (Portulaca grandiflora)

For the hottest, sunniest, and driest spots, Portulaca (or Moss Rose) is the answer. This low-growing succulent annual has fleshy leaves and produces beautiful, cup-shaped flowers that open in the sun.

The yellow varieties are particularly vibrant, looking like little drops of sunshine scattered on the ground. They are perfect for tough spots where nothing else seems to grow.

Shades of Yellow: Bright lemon yellow and deep golden-yellow.
Why You’ll Love It: It’s virtually indestructible, requires very little water, and thrives in conditions that would kill most other plants.
Gardening Tip: Portulaca is ideal for rock gardens or the edge of a hot driveway. When working in these tough, rocky soils, a good pair of protective gloves is a must. The {Ironclad General Utility Work Gloves} offer great durability and protection.

8. Pansy and Viola (Viola species)

While often thought of as spring flowers, pansies and violas are hardy annuals that also perform beautifully in the fall and even through mild winters.

They are the perfect choice for bringing a splash of yellow to your garden when the summer flowers have faded. The pure yellow varieties, often with a small dark blotch, are like little happy faces for your cool-season pots and borders.

Shades of Yellow: Softest primrose, clear lemon, and deep gold, often with contrasting dark “faces.”
Why You’ll Love It: Their frost tolerance is incredible, and they provide cheerful color when you need it most—at the very beginning and end of the gardening season.
Gardening Tip: To keep pansies blooming, pinch off the faded flowers. This prevents them from setting seed and encourages the plant to produce more blooms.

9. Snapdragon (Antirrhinum majus)

Snapdragons are a cool-season favorite with tall, elegant spires of flowers. The yellow varieties are particularly lovely, ranging from soft, buttery pastels to vibrant, saturated yellows.

They add a wonderful vertical element to spring and fall gardens and are fantastic cut flowers. They may stop blooming in the peak of summer heat but will often rebloom as temperatures cool.

Shades of Yellow: Pale butter, lemon yellow, and rich golden yellow.
Why You’ll Love It: They add height, elegance, and a touch of classic cottage charm to the garden. Kids love squeezing the flowers to open the “dragon’s jaw.”
Gardening Tip: Tall snapdragon varieties may need staking to prevent them from flopping over in wind or rain. Simple bamboo stakes and some garden twine work perfectly.

10. Calendula (Calendula officinalis)

Often called “Pot Marigold,” calendula is a wonderfully easy and cheerful hardy annual. It produces simple, daisy-like flowers in sunny shades of yellow and orange.

It thrives in cooler weather and is one of the easiest flowers to grow directly from seed in the garden. The petals are also edible and can be used to add color to salads.

Shades of Yellow: Soft creamy yellow, bright lemon, and deep golden-yellow.
Why You’ll Love It: It’s unfussy, often self-seeds for future years, and the flowers are great for cutting. It’s a classic, no-fail flower for beginners.
Gardening Tip: For a continuous supply of blooms, sow calendula seeds every few weeks in the spring. This succession planting will ensure you have fresh flowers all season.

11. Creeping Zinnia (Sanvitalia procumbens)

This is not your typical zinnia! Creeping zinnia is a low-growing, trailing annual that produces a profusion of tiny, sunflower-like yellow blooms with dark centers. It’s a fantastic groundcover and is perfect for spilling over the edges of pots, baskets, and retaining walls. It’s tough, heat-tolerant, and blooms all summer long.

Shades of Yellow: Bright, golden-yellow with a prominent dark brown or black center.

12. Dahlia (Annual Varieties)

While many dahlias are grown from tubers that must be stored over winter, there are many varieties that are easily grown from seed as annuals.

These “bedding dahlias” produce a wealth of smaller but still beautiful blooms all summer long. The yellow varieties are particularly cheerful and come in a range of forms, from single, open daisies to more complex, ball-shaped flowers.

Why You’ll Love It: They give you the classic, beautiful dahlia flower shape in an easy-to-grow annual form. They are excellent for filling out beds and for cutting.
Gardening Tip: To encourage a bushier plant with more flowers, pinch out the central growing tip when the plant is about a foot tall.

13. Black-Eyed Susan Vine (Thunbergia alata)

This delightful, fast-growing vine is a fantastic annual for adding vertical interest. It produces a continuous supply of charming, five-petaled, bright yellow flowers, each with a distinct, dramatic dark-brown “eye.” It will quickly scramble up a trellis, obelisk, or fence, or can be used to trail from a large hanging basket.

Shades of Yellow: Bright, sunny yellow.
Why You’ll Love It: It’s a fast and easy way to get vertical color. The cheerful flowers with their contrasting centers are incredibly charming.
Gardening Tip: Provide a support structure for it to climb at the time of planting. A simple {Panacea Products Garden Obelisk} placed in a large pot or in the garden bed gives it the perfect framework to grow on.

14. Celosia (Celosia argentea)

For a unique texture in the garden, celosia is a must. The plumed varieties produce soft, feathery spikes of color, while the crested types have a fascinating, brain-like, velvety texture.

Yellow celosia is particularly striking, with colors so vibrant they almost seem to glow. They love heat and are fantastic for adding a “wow” factor.

Shades of Yellow: Bright lemon, intense gold, and fluorescent chartreuse-yellow.
Why You’ll Love It: Its unique shapes and textures add an exotic touch to beds and containers. The flowers are also incredibly long-lasting and are excellent for drying.

15. Yellow Cosmos (Cosmos sulphureus)

While many cosmos come in pink and white, the Cosmos sulphureus species specializes in warm tones, including brilliant yellow.

These cosmos have a slightly different look, with cheerful, semi-double or single flowers in intense shades of yellow and orange. They are just as easy to grow and have the same lovely, airy foliage.

Shades of Yellow: Bright lemon yellow and deep golden-orange.
Why You’ll Love It: It provides a bright, hot-colored version of the beloved, breezy cosmos flower. It thrives in the heat and blooms for months.
