These conversation starters are sure to be the envy of your neighbors. Remember to check the USDA Plant Hardiness Zone before you start to make sure the flowers of your choice are right for your area. You can experiment at any time to find the best combination for your garden style and location.

Let these delicate flowers give your garden a touch of elegance. While they can thrive in some shade, they are best suited for plenty of sunlight and well-drained soil.


If you’re looking for a statement flower to add to your garden, consider thimbles that can easily reach two meters tall. They bloom early in summer and are available in different colors, from pink to white.


Carnations are a symbol of love and distinction and are known for their strong colors and their impressive variety of varieties. Certain carnations can grow up to 24 inches, while others range between 9 and 12 inches.

Hibiscus flowers

You can find these vibrant, trumpet-shaped flowers in a range of color combinations. These flowers are known to attract hummingbirds and butterflies. They need tons of water and fertilizer during their flowering phase.

Oriental lilies

The beauty of the oriental lilies, known for their seductive scent and large flowers, is undeniable. They are also low-maintenance and require a lot of sunlight and moist soil.


This popular summer flower needs well-drained soil, a moderate amount of moisture, and plenty of sunlight to thrive. Keep in mind that wind can damage certain large varieties.


Some Rudbeckia varieties bloom in the summer months. These cheerful flowers are easy to care for and require plenty of sunlight and well-drained soil.


When it comes to begonias, you will find more than 1,000 different types in a range of colors, shapes and sizes. They like damp (rather than soaking wet) soil, moisture, and penumbra.


This flower, also known as amaranth, can grow in size from 18 inches to 6 feet in a variety of colors, including red, orange, gold, green, and purple. This no-till yearbook does not tolerate damp soils, shadows or transplants.

Canna lilies

Try planting these tropical-looking flowers later in the season for lush foliage and color. “Although these flowers only bloom in summer, planting them in spring gives them time to establish themselves and produce intense flowers,” said Missy Henriksen, a spokeswoman for the National Association of Landscape Professionals. They are annuals in cool regions and perennials in warmer ones, she adds.

Lily of the valley

Also called blue lily or African lily, Agapanthus praecox is a full sun or partially shaded flower that thrives in warmer areas, especially in pots. “When it comes to containers and hanging baskets that show signs of stress, it’s best to dwarf them and check for dryness often,” advises Kate Karam, editor-in-chief at Monrovia. “You may need a deep drink at least once or even twice a day.”

Sulfur cosmos

This full sun yearbook is available in cheerful colors, including scarlet, orange and yellow. It is easy to grow from seeds in poorer soils and often sow them yourself, which means less work for you next year. Expect the stems to be 1 to 4 feet tall.

California poppies

Eschscholzia California grows from 6 to 15 inches and comes in red, pink, orange, yellow and cream. This perennial with full sun grows best if it is sown directly because it does not tolerate a good transplant. It also does not thrive in rich or moist soils. Deadhead regularly for continuous flowering throughout the season.

Gazania hybrids

This bright, beautiful flower grows 6 to 15 inches and you can find it in bright colors like red, pink, bronze, orange and yellow. It is a particularly smart choice for sunny, hot, and dry places (i.e., the parched beds on the terrace).

Creeping zinnia

Sanvitalia procumbens is another short perennial, which also only gets 4 to 8 inches high. You can find it in orange or bright yellow. It can work well in partial shade, but does not tolerate poorly drained soil.


Petunias are 6 to 24 inches tall and you can find them in almost any color under the sun. Deadhead for continuous flowering all season, but do not plant in areas with high humidity or frequent rain.

Mexican sunflowers

Tithonia rotundifolia grows anywhere from 30 inches to 8 feet tall. In contrast to most common sunflowers, the growth is rather shrubby and does not tolerate rain or rich soil well. Deadhead regularly for continuous flowering.

Common zinnias

“Zinnias are a traditional plant for pollinators. They are easy to grow and require full sun,” says Henriksen. She recommends using them in borders and container gardens and using the cut flowers for the interior. They can grow anywhere from 4 inches to 4 feet tall and come in almost any color except blue.


If you like pink, choose this showy perennial. The fluffy feathers can grow up to 2 feet tall. Since it is a shade lover, try combining it with hostas or ferns.

Blanket flowers

Gaillardia looks like a miniature sunset that fades between yellow, orange, red and sometimes burgundy. They love bright rays, so don’t hide them in the shade.


From late spring to early autumn, hydrangeas can steal the show in your garden. Try the Blue Enchantress variety for striking ruby-black stems and large mophead flowers, Karam recommends. The marginal shrub blooms blue in acidic soils and pink in alkaline soils. “The flowers age to a cream-coloured vintage color,” she adds.
