30 Prettiest Flowers in the World

Zygopetalum Orchid (Zygopetalum)

Take the inherent beauty of the orchid, and add fantastic speckling and unusual anatomy. You will recognize one of the dozen or so species of the Zygopetalum genus of orchids. Unlike many orchids, the zygopetalum is also very fragrant. Put this robust grower in a hanging basket under the dappled shade of a tree to give it the best lighting conditions. Grow in partial shade in humid conditions, and protect from hot summer temperatures and freezing temperatures.

Dinner Plate Dahlia

Some people automatically think of giant dinner plate-sized blooms at the mention of dahlias, but the Dahlia genus includes a huge diversity of plant and bloom size and flower forms. Choose a variety that has the potential to produce mammoth blooms, like the 'Kevin Floodlight' dinner plate dahlia pictured here. Dahlias require full sun and plenty of fertilizer and water. If you wish, you can remove most of the buds to direct the plant's energy into producing only a few huge blooms. Dinner plate dahlias need a long time to mature and might require a head start indoors north of hardiness zone 5.

Turkscap Lily (Lilium martagon)

So many features of the Turkscap lily (Lilium martagon) make it unique: the impressive four-foot stalks, the pendant-like shape of each blossom, and the profusion of blooms on each stem. Much less common in the trade than Oriental or Asiatic lilies, martagon lilies like their feet in the shade and flowers in the sun in USDA hardiness zones 3 to 8. They need a sheltered spot where they won't be subjected to wind and require excellent drainage. The variety 'R.O. Backhouse' pictured here features pink buds that open to gold flowers dusted with purple freckles.

These plants have very particular growing conditions in zones 3 to 7 and bloom for about two weeks. These eye-catching mountain-grown plants have silky blooms; they are prized for their beauty. The national flower of Bhutan grows best in areas that resemble its native habitat, with cool summers and moist soil. They are only recommended for mountain rock gardens and best in the pacific northwest.1

Delphinium (Delphinium elatum)

Few flowers are as arresting as a healthy stand of Delphinium elatum in full bloom. Delphinium comes in coveted shades of blue from wispy powder puff blue to robust violet and purple. Delphiniums do well in areas with cool or mild summers in zones 3 to 7. They need rich soil, staking, and regular moisture. Delphiniums are extremely cold hardy, but they will not grow well in high humidity climates.

• USDA Hardiness Zones: 4 to 8
  
• Flower Color Varieties: Blue, purple, white, pink, yellow
• Light: Partial shade
• Soil Needs: Moist, well-drained

Foxglove (Digitalis pupurea)

Bumblebees flock to foxglove and love them so dearly they sometimes spend the night in the tubular blossoms so they can get an early start when the sun rises. Foxglove blooms are shaped like glove-like bells and come in various colors and unique patterns that make quite a statement when planted in groups.

These plants are biennial in zones 4-8, meaning they produce foliage their first year and flower the next. However, when self-seeding begins in partial shade and moist soil, you will always have one generation of plants ready to bloom while the next generation grows foliage and prepares to bloom next year. Try 'Mountains Mixed,' which has upright-facing flowers. Be aware that all parts of this plant are toxic to humans and animals.2

The name says it all. While there aren't any unattractive peonies (Paeonia), 'Bowl of Beauty' pictured here is the perfect marriage of color and form. The large circumference of fuchsia guard petals surrounds a frilly lemon center of petals, which creates the bowl. Peonies don't ask for much in their decades of life: full sun and good drainage are enough to produce masses of blooms in average fertile soil. Peonies are exceptionally hardy, to zone 3 and 4, giving northern gardeners something to look forward to after a grueling winter.
