Popular Annuals and Biennials

These plants complete their life cycle in one or two seasons. They are fantastic for providing quick, season-long color. Many are easy to start from seed, giving you a cost-effective way to fill your garden.

Cosmos: These daisy-like flowers dance on slender stems above feathery foliage. They come in pinks, whites, and crimsons and are incredibly easy to grow from seed. They thrive in full sun and poor soil, actually blooming better without too much fertilizer.
Calendula (Pot Marigold): Known for its cheerful orange and yellow blooms, calendula is both edible and medicinal. It often self-seeds, coming back year after year. The petals can be used to add color to salads or in homemade skin salves.
Carnation: A classic cut flower, carnations offer frilly blooms with a distinctive, spicy fragrance. They prefer cooler temperatures and well-drained soil. You can find them in a huge array of solid and bi-colors.
Clarkia: Also called farewell-to-spring, clarkia produces elegant spires of cup-shaped flowers. It does well in cool, coastal climates and can be direct-sown in the garden for a beautiful display.

Essential Perennial Choices

Perennials return year after year, forming the backbone of many gardens. These reliable flowers that start with C will give you lasting structure and recurring beauty with proper care.

Coreopsis: A champion of long bloom time, coreopsis covers itself in sunny yellow, gold, or pink flowers from early summer into fall. It’s drought-tolerant once established and loved by pollinators. Deadheading encourages even more flowers.
Chrysanthemum (Mums): The quintessential fall bloomer, mums provide a vital burst of color when other plants are fading. Plant them in spring so their roots establish before winter. You’ll need to pinch them back in early summer for a bushier shape.
Coneflower (Echinacea): With their bold, daisy-like centers and reflexed petals, coneflowers are a must-have. They are incredibly tough, attract butterflies and birds, and now come in colors from purple and white to vibrant orange and red.
Columbine (Aquilegia): These woodland charmers have unique, spurred flowers that look like little jester’s hats. They are perfect for partial shade and will often happily self-seed around your garden, creating lovely surprises.

Stunning Bulbs and Corms

Plant these once, and they’ll reward you with spectacular blooms for seasons to come. Many of these flowers that start with C are spring highlights, though some bloom in summer.

Crocus: One of the very first signs of spring, crocuses push through snow with their cup-shaped purple, yellow, or white flowers. Plant the corms in fall in a sunny spot for a cheerful early display.
Canna Lily: For a tropical, dramatic effect, canna lilies are unbeatable. They offer large, often colorful leaves and tall spikes of bright flowers. They need full sun, plenty of water, and must be dug up and stored in colder climates.
Cyclamen (Hardy Species): Hardy cyclamen, like Cyclamen hederifolium, are gems for dry shade. They produce delicate, swept-back flowers in fall, followed by beautiful marbled foliage. They are small but incredibly persistant once happy.

Shrubs and Climbing Vines

Add height and structure to your garden with these woody plants. They provide a bigger impact and can serve as focal points or living screens.

Clematis: This premier climbing vine offers some of the most spectacular blooms in the garden. Clematis varieties bloom at different times; some flower on old wood, others on new. The key is to keep their roots cool and shaded while their tops bask in the sun.
Camellia: An evergreen shrub with glossy leaves and exquisite rose-like flowers, camellia blooms in late fall, winter, or early spring. They prefer acidic soil, partial shade, and protection from harsh morning sun in colder zones.
Crape Myrtle (Lagerstroemia): Celebrated for its long summer bloom period, exfoliating bark, and brilliant fall color. It loves heat and full sun. Choose a disease-resistant variety and give it plenty of space to grow to its natural shape.

How to Plant and Care for Your “C” Flowers

Success starts with putting the right plant in the right place. Always check the specific needs for each flower, but these general steps will set you up for success.

Check Your Zone and Sun: First, know your USDA Hardiness Zone. Match plants to your zone. Then, observe how much sun your garden area gets—full sun (6+ hours), part sun, or full shade.
Prepare the Soil: Most flowering plants prefer well-drained soil. Work in several inches of compost to improve texture and fertility. Good soil is the foundation of a healthy garden.
Plant at the Right Depth: For potted plants, plant at the same depth they were in the pot. For bulbs, follow the package instructions, usually 2-3 times the bulb’s height deep.
Water Wisely: Water deeply after planting to settle the soil. Then, water regularly until plants are established. After that, many of these flowers are quite drought-tolerant.
Feed for Flowers: Use a balanced, slow-release fertilizer in spring. For heavy bloomers like cosmos or coneflowers, a light feed mid-season can be helpful. Avoid high-nitrogen fertilizers, which promote leaves over blooms.

Design Tips for a Captivating Display

Think about how these flowers work together. You can create stunning visual effects by considering color, height, and bloom time.

Layer by Height: Place taller flowers like cannas or clematis (on a trellis) at the back of a border, with mid-height plants like coneflowers and coreopsis in the middle, and low growers like crocus or calendula at the front.
Plan for Succession: Choose flowers that bloom at different times. For example, start with crocus in spring, follow with columbine and coreopsis in early summer, then coneflowers in high summer, and finish with chrysanthemums in fall.
Combine Colors Thoughtfully: For a calming effect, pair similar colors, like purple clematis with pink cosmos. For a vibrant, energetic bed, combine complementary colors like the orange of calendula with the blue of other non-C flowers like salvia.
