45 Beautiful Cosmos Cultivars for Your Flowerbeds
Are you looking for some Cosmos flowers to add to your garden this season, but aren't sure which to pick? There are many different types of cosmos, and many will grow quite well as annuals across hardiness zones. In this article, certified master gardener Liz Jaros shares her favorite types of cosmos flowers, with names and pictures of each!
Contents
Diverse in color and height, easy to grow, and tolerant of drought, cosmos flowers can be counted on to bring the garden goodness all season long. Peppering landscapes from zone 2 through zone 11 in shades of pink, red, orange, yellow, and white, these classic beauties range from just 8 inches to nearly 6 feet in height.
As members of the Asteraceae family, species in the Cosmos genus produce ray-shaped flowers that resemble their daisy, aster, and sunflower cousins. Although the Cosmos genus has roughly 30 known species, the varieties we grow in our yards and on our patios are typically from the bipinnatus, astrosanguineus, or sulphureus species.
All are native to Mexico, South America, and the Southwest United States and have a high tolerance for hot sun once they get growing. Most are treated like annual flowers in the garden, but some will return perennially in warmer regions.
If you’d like to work some cosmos into your landscape this season but are feeling overwhelmed by your options, think about height and color scheme first. This will help narrow down your selections. To help you make final decisions, we’ve gathered photos, growing information, and detailed descriptions of 45 of our favorites:
‘Rubenza’
botanical name Cosmos bipinnatus ‘Rubenza’ | |
plant type Annual | |
bloom colors Ruby red, rose | |
sun requirements Full sun | |
height 1-2 feet | |
hardiness zones 2-11 |
Flowers are a deep ruby red when blooms first open, maturing to a dusty rose color later in the season and averaging 3 inches across. Petals are obovate (egg-shaped) and finely textured with horizontal lines. Petal exteriors are scalloped and slightly ruffled. Central disks are bright and very attractive to pollinators.
Plant ‘Rubenza’ in a mixed border or a container with some kind of spiller around its legs. Pinch sprouts after it has three sets of leaves to encourage side growth and a bushier habit. Foliage is finely textured and very bright green.
‘Ladybird’
botanical name Cosmos sulphureus ‘Ladybird Dwarf’ | |
plant type Annual | |
bloom colors orange, yellow | |
sun requirements Full sun | |
height 12-16 inches | |
hardiness zones 2-11 |
Brilliant in shades of orange and yellow, ‘Ladybird’ dwarf cosmos are often mistaken for marigolds in the garden. Centers are the same color as petals, which are scalloped and curve inward slightly at their perimeters. Blooms are considered semi-double in form as there are at least two layers of overlapping petals.
Leaves are dark and olive-colored with a firm stature that resembles rosemary. As a species native to Central America, sulphureus cosmos all have great heat tolerance and prefer dry, well-draining soil that is not overly fertile. Ladybird flowers take well to cutting and look lovely in a vase but can only be expected to live for 5-7 days in water.
‘Rosetta’
botanical name Cosmos bipinnatus ‘Rosetta’ | |
plant type Annual | |
bloom colors pink, blush, rose, white | |
sun requirements Full sun | |

Featuring beautiful, semi-double flowers up to 4 inches wide, ‘Rosetta’ cosmos are flirty and feminine in any setting. Petals are rosy, pink with white stripes and sheared edges. Central disks are encircled by another set of smaller, paler petals that flip upward slightly.
Leaves are sparse and small, radiating out from slender stems that branch whimsically like a wildflower. Deadhead spent flowers and this variety will keep blooming long into the fall. Seeds may self-sow if spent flower heads are left in place or tilled into the top layer of dirt at the end of the season.
‘Rose Bon Bon’
botanical name Cosmos bipinnatus ‘Rose Bon Bon’ | |
plant type Annual | |
bloom colors lavender, pink | |
sun requirements Full sun | |
height 3-4 feet | |
hardiness zones 2-11 |
This delightful, frilly cosmos features tightly compact flowers in shades of lavender and pink. Blooms are fully double with numerous layers of small, ruffled petals encircling a green to yellow central disk. The overall effect is something akin to a carnation.
Tall in stature, ‘Rose Bon Bon’ can reach heights of up to 4 feet and is best featured at the back of a border. Foliage is feathery and supportive along stems that are gangly and multi-branched. Consider staking them if plants will be exposed to high winds or heavy rains. Make sure soil does not hold water, as cosmos are prone to flopping and do not like wet feet.
‘Cosmic Orange’
botanical name Cosmos sulphureus ‘Cosmic Orange’ | |
plant type Annual | |
bloom colors Orange | |
sun requirements Full sun | |
height 1-2 feet | |
hardiness zones 2-11 |
Blooms on this cheerful cosmos variety are small but plentiful. Averaging 2 inches across, flowers are semi-double form with multiple layers of carrot-orange petals radiating from a prominent central disk of the same color.
Foliage on sulphureus cosmos varieties is larger and more prominent than bipinnatus cosmos. Leaves are dark green in color and similar to a carrot or marigold leave in form. This variety has a more rounded habit and works well in the container garden or border front. ‘Cosmic Orange’ may self-sow sporadically but will not become a nuisance spreader.
‘Pink Popsocks’
botanical name Cosmos bipinnatus ‘Pink Popsocks’ | |
plant type Annual | |
bloom colors Dark pink | |
sun requirements Full sun | |
height 18-24 inches | |
hardiness zones 2-11 |
Bloom types vary from single to anemone to pompon form on this precious pink cosmos cultivar. Fuschia to mauve pink petals fan out from a yellow central disc that evolves throughout the season, taking on a powderpuff shape in later months.
Thin, thready leaves are more substantial and densely packed than other cosmos foliage. This creates a fluffy, green cushion beneath ‘Pink Popsocks’ brilliant blooms. Expect this variety to last between 5 and 7 days after cutting.

plant type Annual | |
bloom colors Pink, red | |
sun requirements Full sun | |
height 2-3 feet | |
hardiness zones 2-11 |
Blooms can be cherry pink to crimson red on this common cosmos. Petals cup inward slightly, while bright yellow centers invite bees and butterflies to the garden. At 2-3 feet, ‘Gazebo Red’s’ average height makes it a natural choice for middle border plantings.
Deadhead as soon as flower heads have faded and blooms will keep coming for the entire growing season. Stems are gangly and may benefit from staking if you’re planting in an area that will receive high winds. Leaves are finely textured and vivid green in color.

height 4-5 feet | |
hardiness zones 2-11 |

Use ‘Radiance’ at the back of a mixed bed, as flowers generally drift above the foliage, and foreground perennials will stand out against its bright green base. If you plan to cut some of these lovely blooms for an interior arrangement, wait until flower buds have begun to open slightly.
‘Purity’

plant type Annual | |
bloom colors White | |

Blooms are frilly and feminine on this double bloom, baby pink cosmos. Outer petals have sheared tips and are substantial and densely layered. Inner petals are smaller and more ovate, standing upright as they surround sunny yellow central disks.
Resembling carnations, ‘Fizzy Pink’ cosmos look beautiful in a vase. Although cut blooms will last less than a week in water, the mother plant will continue to produce flowers until cold temperatures move in.

Averaging 3-4 feet tall and wide, this cosmos cultivar behaves more like a shrub than an annual flower. With a rounded habit and a dense branching pattern, ‘Tango’ offers a multitude of small but bold flowers in shades of carrot, pumpkin, and tangerine orange.
Native to the mountains of Mexico, ‘Tango’ looks at home in an open area with lots of sunshine. But it will also dazzle in a large pot on the patio. Although this is technically an annual plant, gardeners in warm regions can turn plants over into the soil and seeds will self-sow.
Final Thoughts
Cosmos flowers are drought tolerant annual flowers that are easy to grow from seed. These relatively maintenance free flowers provide a wonderful pop of color wherever they’re planted. Pinch young plants to encourage a more rounded branching habit and you won’t need to worry much about staking or support. Deadhead often to keep blooms coming, and definitely include some in the cutting garden! You’ll be glad you did.
