Dahlia refers to a genus of plants that belongs to the family Asteraceae. The flowers were first discovered in Mexico, where they were cultivated as a food source. Now, they are one of the most popular flowering plants in the world.
According to the American Dahlia Society, there are 35 different varieties of dahlias, which are divided into 13 different groups. These groups include the anemone-flowered group, the ball group, the decorative group, the formal decorative group, the informal decorative group, the cactus-flowered group, the collarette group, the waterlily-flowered group, and more.
The first question you might have is, ‘How many varieties of dahlias are there?’ This answer depends on how you define the word ‘variety’. There are several types of Dahlias, such as ‘Happy Single Wink’, ‘Eveline’, ‘Chat noir’ and ‘Dutch Explosion.’ But how do you distinguish between these varieties?
‘Happy Single Wink’
The ‘Happy Single Wink’ Dahlie is a simple, bushy perennial with pinnate, toothed leaves. It bears single, deep pink flowers, with dark red petal bases. It is tolerant of a variety of soils, but can be susceptible to virus and fungal rots. Despite its popularity, it is best not to plant this Dahlia in a pot until it is established in a sunny location.
The ‘Happy Single’ Dahlia is a recent introduction to the Dahlia family. This variety features single, 8-cm-wide flowers with a rose-centred halo. The flower is also surrounded by a large purple-red centre. ‘Happy Single’ Dahlia grows to about 60cm/2ft. Tall, but not overly large, this Dahlia is a good choice for a patio or small garden.
This Dahlia is hardy in USDA zones 8 to 11. It blooms from July to the first frost. The plant can be grown in a container. The plant will grow up to eight inches (20 cm) tall. It grows well in full sunlight and tolerates a neutral pH. ‘Happy Single Wink’ Dahlia is a beautiful and easy-to-grow plant for the home garden.
The ‘Happy Single Wink’ Dahli resembles a classic red heart. Its flower is symmetrical and features a white center. Dahlias are native to Mexico, Central America, and Columbia. The Aztecs grew them for food and for medicinal purposes, and the tubers are edible. Dahlias were originally cultivated by the Aztecs for their edible tubers. The name Dahlia comes from the Swedish botanist Anders Dahl. The Dahlia is now considered the national flower of Mexico.
The ‘Eveline’ Dahlia is the tallest and most impressive variety of Dahlias, reaching 36 to 48 inches. The flowers are ivory in color with a touch of lavender at the center and on the petal tips. This variety is excellent for cut arrangements and is pre-sale until spring 2022. It grows three to four feet high. Its long, straight stems make it an excellent choice for container gardening.
This dahlia grows in zones 8-10. The plant has tall, upright stems and toothed pinnate dark green leaves. It bears flowers in late summer and into early fall. It is susceptible to fungal rots and viruses. When cutting back the plant in fall, the foliage should be removed to the ground. If the plant continues to grow over the winter, it is best to divide and replant it the following spring.
‘Eveline’ Dahlia is best planted in pots that have a diameter of 12 inches. Planting tubers outdoors after frost is over is best, but they can also be started in pots under glass in late winter. The Dahlias should be planted between 20 and 50 cm apart, with the eyes at the top. It should be staked if its stems get wilted. The Dahlia will respond well to manure, compost, and mineral fertilizer.
The ‘Chat noir’ Dahlia is an outstanding garden plant that is sure to turn heads. Its rich red fonce color is striking and complemented by the plant’s gray leaves. This Dahlia pairs well with fenouils, kochias, nigelles, echinaceas, hyacinths, lindheimia, and helenium. It also looks great with miscanthus, hydrangea, and sedums.
‘Chat Noir’ Dahlias have a wonderful vase life and are very long-lasting. Their deep red flowers are spectacular and resemble sea urchins. They are a full 6 to 8 inches across and contain very little water, so they remain upright in rain. The ‘Chat noir’ Dahlia has excellent vase life and is suitable for gardens and containers. If you want to add a touch of drama to your border, plant Chat Noir dahlias in a generous group. This Dahlia will work well with boldly coloured plants, such as Foeniculum vulgare ‘Giant Bronze’, and ornamental grasses.
The ‘Chat noir’ Dahlia has deep red petals, and its flowers are reminiscent of 19th century Paris cabarets. It is a large flowering cactus Dahlia that grows up to 80cm. They are excellent for borders, container gardening, and cutting. The tubers are supplied in top-grade tubers. They are easy to grow and maintain. They will flower all summer long.
The Dutch Explosion Dahlia is one of the most prized cactus flowers. Its beautiful, four-inch blooms are colored white with a bright pink tip. It grows to a height of 2.5-3.5 feet. Dutch Explosion is an excellent choice for a summer or fall garden border. It can also be used as cut flowers. This cactus type is suitable for both pots and gardens.
The Dutch Explosion Dahlia is an upright, bushy perennial with large, toothed, dark green leaves. Double flowers with magenta-to-deep pink petal tips appear throughout the summer. Dutch Explosion is susceptible to fungal rot and viruses. In autumn, it should be pruned back to a near-ground level and its tubers lifted. Its bloom period lasts for three to five months.
The Dutch Explosion Dahlia grows well in partial or full sunlight, and blooms profusely from June to August. The tuber should be stored in a frost-free location after flowering to protect the tuber. Dahlia ‘Dutch Explosion’ pairs well with many other varieties. Its dark pink flowers are perfect for cutting, and the plant is highly fragrant. You can also place stems in lukewarm water to prolong their life.
The word “dahlia” means “flower,” but the species of dahlia is much more complex. There are actually over 57,000 different types of dahlias. Dahlias are perennial plants, but grow as annuals in colder climates. Although they are perennial, some dahlias have herbaceous stems, which are lignified and resprout after winter dormancy. Dahlia flowers are composed of composite flower heads with ray florets extending from the center. Each floret is a flower in its own right, so there is no way to classify a dahlia by its floret number, but horticulturists wrongly call the individual floret a petal.
In 1825, Nicolas-Joseph Thiery de Menonville, a French botanist, visited Mexico and stole parts of the cochineal insect, which was prized for its scarlet dye. Vicente Cervantes then sent them to his friend Abbe Antonio Jose Cavanilles in Spain. The result was the creation of two new varieties of dahlia – the doubles.
Single Dahlias come in many different shapes and sizes. Some are symmetrical, with a row of petals in one direction. Some have petaloids that overlap in a ring, and other varieties have petals that are flat or slightly cupped. ‘Pooh’, for example, is named after the beloved bear. Single Dahlias are typically smaller than doubles, and the petals are usually a single row. Dahlias are also grouped by color. ‘Bright Eyes’ has pink petals, and ‘Northlake Pride has purple petals and spines.
‘Anemone flowerered’ Dahlies are elegant plants with delicately striped petals. They bloom for several months from midsummer until frost and have a subtle orange/pink color. The flowers are about three inches in diameter and crown towering stems. This Dahlia is deer resistant and hardy to coastal British Columbia winter temperatures. It will grow up to two feet tall and bear flowers for many months.
This Dahlia is unique in that the flowers resemble an anemone with dark petals around the center pincushion. The tiny yellow highlights on the petals are reminiscent of a honeycomb. The compact plant is a beauty in a bouquet. ‘Anemone flowerered’ Dahlia produces lots of flowers and is perfect for containers and gardens. It will bloom well into the fall in many climates.
The crimson-pink flowers of the ‘Soulman’ anemone dahlia make this a star for many gardeners. Its long, flat petals, and narrow central petal make it easy to spot in a garden. ‘Soulman’ has a distinctive shape and colour that harmonizes with day lilies and taller sage cultivars.
‘Anemone flowerered’ Dahlium’s outer ray floret rings are pink with a yellow center. Compact, two-foot plants never need staking and are perfect for borders, flower beds, and containers. Dahlias have tiny tubers and are generally easy to grow in a pot. You can buy hybrid varieties or grow them in a garden as an annual or perennial.
