Blooming Plants With The Largest Flowers

Hibiscus (Hibiscus rosa-sinensis) 

Plants

Hibiscus flowers are widely admired for their size and exotic beauty, with some varieties producing blooms over a foot in diameter. These vibrant flowers come in many colors, including red, pink, orange, and yellow, each adding a tropical flair to temperate gardens. The Hibiscus is a versatile plant that can be grown in the ground or in containers, making it suitable for various garden settings. Its lush, glossy foliage provides a beautiful backdrop for its large, conspicuous flowers, which can bloom continuously in optimal conditions.

When growing Hibiscus, it’s important to consider its need for warmth and protection from cold temperatures. This plant prefers full sun to partial shade and requires moist, well-draining soil rich in organic matter. Regular pruning will help maintain its shape and encourage more blooms. In colder regions, Hibiscus can be overwintered indoors or in a greenhouse to protect it from frost, ensuring its survival and continued growth year after year.

Tree Peony (Paeonia suffruticosa) 

Plants

Tree Peonies are distinguished by their woody stems and large, multi-petaled flowers reaching up to 10 inches in diameter. These perennial shrubs are known for their colors, including shades of pink, red, yellow, and white. The Tree Peony’s substantial size and stunning blooms make it a focal point in any garden, attracting admirers with its bold yet delicate appearance. Unlike herbaceous peonies, Tree Peonies do not die back to the ground yearly and can live for decades, contributing lasting beauty to garden landscapes.

Caring for Tree Peonies involves choosing a sheltered location that provides at least half a day of sunlight and protection from harsh winds. They thrive in well-drained, fertile soil with a neutral to slightly alkaline pH. Watering should be done deeply but infrequently, allowing the soil to dry out slightly between waterings. Proper care also includes the application of a balanced fertilizer in early spring to promote vigorous growth and abundant flowering. Pruning should be minimal, focusing only on removing dead or broken branches to maintain the plant’s health and aesthetic appeal.

Dinner Plate Dahlia (Dahlia x hortensis) 

Plants

Dinner Plate Dahlias are celebrated for their large and vibrant blooms, measuring up to 12 inches across. These flowers come in various colors and forms, making them highly prized for garden display and floral arrangements. Their name aptly reflects the size of the blooms, which resemble large dinner plates. Gardeners can enjoy an extended blooming period from midsummer through fall, as Dahlias produce new flowers until the first frost. Dinner Plate Dahlias’s impressive size and vivid colors make them a standout addition to any garden.

To achieve the best results with Dinner Plate Dahlias, they should be planted in a location that receives full sun. The soil must be rich, well-draining, and moist throughout the growing season. Staking is essential for supporting the heavy blooms, preventing the stems from bending or breaking. Regular deadheading will encourage continued flowering and maintain the plant’s energy focus on bloom production. Additionally, since Dahlias are not frost-tolerant, tubers should be lifted and stored in a cool, dry place during winter in colder climates.

Magnolia (Magnolia grandiflora) 

Plants

Magnolias are revered for their large, aromatic blossoms, which can be up to 12 inches in diameter. These trees are an emblem of the South in the United States but are adaptable to various climates. The glorious white flowers add aesthetic value to the landscape and emit a sweet, citrus-like fragrance that perfumes the air. Magnolia trees can provide shade and structure to garden designs, making them an excellent choice for those looking to combine functionality with beauty.

Planting a Magnolia requires consideration of its long-term growth as these trees can become quite large. They prefer a sunny spot with well-draining soil that retains moisture. Young trees should be watered regularly until they are well-established. Magnolias are relatively low maintenance but benefit from mulching to help retain soil moisture and regulate temperature. Minimal pruning is required to maintain their shape and remove any dead or damaged branches, which should be done after flowering to avoid cutting off next year’s buds.
