In Chinese herbal medicine, certain lily species, particularly Lilium brownii var. viridulum, are believed to have therapeutic properties. The bulbs are used to nourish yin (the cooling, moisturizing aspect of the body), soothe the lungs, and promote tranquility. These effects are thought to be beneficial for dry coughs, insomnia, and anxiety.

Culinary applications of lilies are also noteworthy. In Asian cuisine, particularly Chinese cooking, lily bulbs are a delicacy. They have a mild, slightly sweet flavor and a crisp texture when fresh. When dried, they become tender upon rehydration. Lily bulbs are often used in soups, stir-fries, and desserts. A popular dish is lily and tremella soup, which combines the subtle taste of lily bulbs with the gelatinous texture of tremella fungus, creating a nutritious and refreshing dish.

It’s important to note that while some lily species are edible, others can be toxic. Only consume lilies that are specifically cultivated for culinary use and properly identified by experts. Additionally, many ornamental lilies can be highly toxic to cats, so pet owners should exercise caution when bringing these flowers into their homes.

5. Night-blooming Cereus

Flowers That Bloom in Summer

The night-blooming cereus (Epiphyllum oxypetalum) is one of the most enigmatic and ephemeral flowers of summer. Often poetically referred to as “Queen of the Night” or “Kadupul flower,” this extraordinary cactus species is renowned for its fleeting nocturnal blooms. The flowering period is remarkably brief, typically lasting only 6-8 hours, with the blossoms unfurling in silent splendor under the cover of darkness.

To witness the rare beauty of the night-blooming cereus, one must be vigilant and prepared during its peak blooming season, which spans from late spring through early fall (May to September). The exact timing can vary depending on environmental factors and the specific variety. These plants tend to flower more prolifically during the warmest months, particularly from June to August.

Observing a night-blooming cereus in bloom requires patience and attentiveness. The flower buds develop slowly over several weeks, but the actual blooming occurs rapidly. As evening approaches, the buds begin to swell and gradually open, reaching full bloom around midnight. The large, white, highly fragrant flowers can measure up to 6-8 inches (15-20 cm) in diameter, creating a spectacular nocturnal display.

Enthusiasts and botanists often organize “bloom watches” to catch this fleeting event. Some species of night-blooming cereus may bloom multiple times during the season, while others produce only one or two flowers per year, making each bloom a truly special occurrence.

The short-lived nature of these flowers is an evolutionary adaptation. By blooming at night, the plant attracts nocturnal pollinators such as moths and bats, which are drawn to the flower’s strong, sweet fragrance and brilliant white color that stands out in the darkness.

For those cultivating night-blooming cereus at home, providing the right conditions can encourage more frequent blooming. These plants prefer bright, indirect light during the day and complete darkness at night. They thrive in well-draining soil and benefit from a period of relative drought before flowering.

One of the most fascinating characteristics of sunflowers is their heliotropic behavior during the budding stage. Young sunflower buds and leaves exhibit phototropism, following the sun’s movement from east to west throughout the day. This sun-tracking ability, known as heliotropism, ceases once the flower fully blooms, at which point most sunflowers permanently face east. This behavior has earned them their common name “sunflowers.”

Sunflowers are not only ornamental but also highly valuable as a crop. The seeds, rich in nutrients, can be harvested when the flower heads have fully matured and dried. These seeds are versatile in their use:

  1. Culinary: Seeds can be dried and roasted, then consumed as a nutritious snack. They’re also used in baking, as a salad topping, or pressed for their oil.
  2. Wildlife feed: Sunflower seeds are an excellent food source for birds and small mammals.
  3. Agricultural: They’re used as livestock feed and in the production of biodiesel.

The sunflower’s tall stalks, broad leaves, and large flower heads make it an excellent choice for creating natural privacy screens or background plantings in gardens. With proper care, including full sun exposure and well-draining soil, sunflowers can grow to impressive heights, with some varieties reaching up to 16 feet tall.

In addition to their practical uses, sunflowers hold cultural significance in many societies, often symbolizing adoration, loyalty, and longevity. Their cheerful appearance and easy cultivation have made them a favorite among gardeners and nature enthusiasts worldwide.

With its ease of cultivation, stunning appearance, and ecological benefits, Ammi majus is a rewarding choice for both novice and experienced gardeners alike. Whether grown in containers, flower beds, or naturalized areas, it adds a touch of delicate beauty to any garden setting.

23. Beauty Cherry (Four O’Clocks)

Flowers That Bloom in Summer

Beauty cherry, scientifically known as Mirabilis jalapa and commonly called Four O’Clocks or Marvel of Peru, is a perennial herbaceous plant often grown as an annual in cooler climates. This species boasts an elegant stature, vibrant color palette, and enchanting blossoms that create a mesmerizing floral display, captivating observers and enticing them to linger.

The plant forms bushy, multi-branched clusters reaching heights of 2-3 feet (60-90 cm). Its flowering structure consists of trumpet-shaped blooms arranged in terminal clusters, creating an umbrella-like appearance. Each flower opens in the late afternoon, typically around 4 p.m., hence the common name “Four O’Clocks.”

Four O’Clocks exhibit a diverse color range, including white, red, magenta, yellow, pink, and sometimes bi-colored varieties. This versatility makes them ideal for container gardening, border plantings, or as vibrant additions to flower beds.

Flowers That Bloom in Summer

In addition to the Blue Snowflake Flower (Thunbergia grandiflora) and the Golden Dew Flower (Duranta erecta), another remarkable vine suitable for summer cultivation is the Fragrant Trumpet Vine (Campsis radicans), known for its trumpet-shaped blooms and sweet fragrance.

The Fragrant Trumpet Vine boasts an impressively long flowering period, gracing gardens with continuous blooms from early summer through fall. Its large, trumpet-shaped flowers, typically in shades of orange or red, are not only visually striking but also emit a pleasant fragrance, attracting hummingbirds and butterflies.

It’s crucial to distinguish between the Fragrant Trumpet Vine and the Red Cicada Flower (Pyrostegia venusta), as confusion between these two plants is common in the horticultural market. Many vendors mistakenly sell Red Cicada Flower as Fragrant Trumpet Vine, leading to disappointment among gardeners.

Key differences between these plants include:

  1. Fragrance: True to its name, the Fragrant Trumpet Vine produces scented flowers, while the Red Cicada Flower lacks fragrance.
  2. Climbing habit: Fragrant Trumpet Vine is a vigorous climber with strong aerial rootlets, easily scaling walls and trellises. Red Cicada Flower, while also a climber, tends to be less aggressive and may require more support.
  3. Flower shape and color: Fragrant Trumpet Vine flowers are larger and more flared, typically orange or red. Red Cicada Flower blooms are usually bright orange-red and more tubular in shape.
  4. Foliage: Fragrant Trumpet Vine has compound leaves with 7-11 leaflets, while Red Cicada Flower has compound leaves with 2-3 leaflets.
  5. Bloom time: Fragrant Trumpet Vine flowers in summer and early fall, while Red Cicada Flower typically blooms in late winter to early spring.

Flower enthusiasts should be aware of these differences when purchasing plants. To ensure you’re getting the genuine Fragrant Trumpet Vine, it’s advisable to buy from reputable nurseries or specialist growers who can provide accurate plant identification. Always check the botanical name (Campsis radicans for Fragrant Trumpet Vine) to avoid confusion with the Red Cicada Flower (Pyrostegia venusta).

Both plants have their merits in landscape design, but understanding their distinct characteristics will help gardeners make informed choices and set appropriate expectations for their summer-blooming vines.

25. Milan Flower (Aglaia odorata)

Flowers That Bloom in Summer

In addition to Jasmine, the Milan Flower (Aglaia odorata) is another excellent choice for summer cultivation. This plant, also known as Chinese Perfume Plant or Chinese Rice Flower, derives its common name from the resemblance of its tiny, globular flowers to small grains of rice when in bloom.

While the visual appeal of Milan Flower is undeniable, its most striking feature is its intense, sweet fragrance. The scent is often described as a complex blend of jasmine, gardenia, and vanilla, making it a prized addition to fragrant gardens.

Aglaia odorata is a warmth-loving, evergreen shrub or small tree native to Southeast Asia. It boasts attractive, glossy, dark green compound leaves that provide year-round ornamental value. The foliage consists of 3-5 leaflets arranged pinnately, adding to its aesthetic appeal even when not in flower.

As a member of the Meliaceae family, Milan Flower falls into the category of aromatic plants that offer dual ornamental value through both their flowers and foliage.

26. Four O’Clock Flower (Mirabilis jalapa)

Flowers That Bloom in Summer

The Four O’Clock Flower, scientifically known as Mirabilis jalapa, is a captivating ornamental plant that deserves attention in summer gardens. This species, native to tropical America, is prized for its colorful, fragrant blooms that typically open in the late afternoon, hence its common name.

The traditional light pink varieties are notably resilient and low-maintenance, making them an excellent choice for novice and experienced gardeners alike. These robust cultivars thrive when directly sown in the ground. Simply scatter the seeds in a sunny to partially shaded area with well-draining soil, and they will flourish into a stunning floral display with minimal intervention. Their self-seeding nature often results in volunteer plants in subsequent seasons, creating a naturalized garden effect.

For those who prefer container gardening or have limited space, imported dwarf or trailing varieties of Four O’Clock Flower offer attractive alternatives. These cultivars are bred for compact growth or cascading habits, making them ideal for pots, hanging baskets, or window boxes. Their diverse color palette, including vibrant yellows, magentas, and bi-color patterns, can add a striking visual element to your garden design.

However, it’s important to note that these specialized imported varieties, while visually appealing, generally exhibit lower resistance to environmental stresses compared to their upright, light pink counterparts.

Regardless of the variety chosen, all Four O’Clock Flowers benefit from full sun to partial shade and moderately fertile, well-draining soil. Regular deadheading can promote continuous blooming throughout the summer and into early fall. With proper care, these versatile plants can become a cherished addition to your summer garden, offering both beauty and fragrance in the late afternoon and evening hours.

27. Hibiscus

Flowers That Bloom in Summer

Hibiscus, a genus in the mallow family (Malvaceae), is renowned for its stunning diversity of colors, large showy flowers, and impressive stature. These versatile plants offer a wide array of cultivars, with flowers ranging from vibrant reds and pinks to subtle whites and yellows, often featuring intricate patterns and multiple layers of petals. The plants themselves can vary from compact shrubs to small trees, depending on the species and cultivar.

Hibiscus is an excellent choice for creating dramatic visual impact in landscapes. Its versatility makes it ideal for various planting scenarios:

  1. Along walls: Creates a colorful, living backdrop
  2. Roadsides: Provides aesthetic appeal and potential erosion control
  3. Slopes: Offers both beauty and practical soil stabilization
  4. Water edges: Thrives in moist environments, enhancing waterside aesthetics

Hibiscus plants are heliotropic, meaning they thrive in full sun exposure. They require a minimum of 6 hours of direct sunlight daily for optimal growth and flowering. While they can tolerate partial shade, insufficient light may result in reduced blooming and potentially weaker stem growth.

The cold hardiness of Hibiscus varies among species and cultivars. Many perennial varieties, particularly those native to temperate regions, have robust root systems that can withstand cold temperatures. This characteristic allows them to successfully overwinter in northern regions of China and similar climates. However, it’s important to note that tropical Hibiscus species may require winter protection or indoor cultivation in colder areas.

The primary flowering period for most Hibiscus varieties extends from early summer through late summer (June to August). However, with proper care and favorable conditions, some cultivars may continue blooming into early fall. Each individual flower typically lasts only a day or two, but the plants produce new blooms continuously throughout the season.

To maximize the health and beauty of Hibiscus:

  1. Soil: Plant in well-draining, rich soil amended with organic matter
  2. Watering: Maintain consistent moisture, especially during flowering
  3. Fertilization: Apply a balanced, slow-release fertilizer in spring and mid-summer
  4. Pruning: Shape and encourage bushiness by pruning in late winter or early spring
  5. Pest management: Monitor for common pests like aphids and whiteflies, treating as necessary

By providing these optimal growing conditions, gar

28. Cosmos Flower

Flowers That Bloom in Summer

The Cosmos flower (Cosmos bipinnatus) is an excellent choice for mass planting, offering a stunning display with minimal effort. This annual plant is prized for its rapid growth, extended blooming period, and low-maintenance nature.

To create a beautiful cosmos display, simply scatter the seeds in a prepared bed. These resilient plants will quickly germinate and establish themselves, rewarding gardeners with a profusion of daisy-like flowers in shades of pink, white, and magenta. The blooming period typically extends from early summer until the first frost, providing months of colorful interest in the garden.

While cosmos are relatively easy to grow, they do have some specific requirements for optimal performance:

  1. Sunlight: Cosmos thrive in full sun, requiring at least 6-8 hours of direct sunlight daily.
  2. Soil: They prefer well-draining, moderately fertile soil. Overly rich soil can lead to excessive foliage growth at the expense of flowers.
  3. Location: Choose a site that offers some protection from strong winds. Cosmos can grow quite tall, reaching heights of 3-6 feet (90-180 cm), making them susceptible to wind damage.
  4. Spacing: During the seedling stage, it’s crucial to thin the plants. Space them about 12-18 inches (30-45 cm) apart to reduce competition and prevent overcrowding, which can lead to weak stems and increase the risk of lodging (plants falling over).

Although Marigolds share some similarities with Chrysanthemums, as both belong to the Asteraceae family, they possess unique characteristics that set them apart. The most notable distinction lies in their floral coloration.

Marigolds boast vibrant, often bicolored blooms, with petals displaying different hues on their front and back surfaces. This creates a captivating visual effect, especially when the flowers catch the breeze. In contrast, Chrysanthemums typically exhibit monochromatic flowers, though they offer a wide range of colors within the species.

Marigolds are prized for their rich, warm color palette, ranging from bright yellows and deep oranges to rich reds and russet browns. This vivid array of hues contributes to their popularity in garden design, adding a bold and cheerful element to flower beds, borders, and containers.

Beyond their aesthetic appeal, Marigolds offer practical benefits in the garden. Their strong scent and natural compounds make them effective companion plants, helping to repel pests from nearby vegetables and herbs. Additionally, certain Marigold species are edible, with their petals used to add color and a slightly spicy flavor to salads and other dishes.

Marigolds are also remarkably easy to grow, tolerating a wide range of soil conditions and thriving in full sun. Their long blooming period, often lasting from late spring until the first frost, ensures a continuous display of color throughout the growing season. This combination of vibrant appearance, practical benefits, and low maintenance requirements makes Marigolds a favorite among both novice and experienced gardeners alike.

32. Morning Glory Vine

Flowers That Bloom in Summer

Morning Glory Vine (Ipomoea spp.), a close relative of the well-known Morning Glory flower, is a vigorous climber that gracefully twines around support structures. This annual herb produces an abundance of small, star-shaped flowers, often referred to as star flowers. The blossoms are typically a deep, vibrant red, creating a striking display against the vine’s lush green foliage. One of the most appealing characteristics of Morning Glory Vine is its impressively long flowering period.

As a sun-loving plant, Morning Glory Vine thrives in warm, moist, and sunny environments. It requires full sun exposure for optimal growth and flowering. The vine is not cold-tolerant, making it best suited for cultivation in temperate to tropical climates or as a summer annual in cooler regions.
