From Aztec Fields to Indian Gardens: The Journey of the Dahlia
The dahlia traces its roots to the highlands of Mexico and Central America, where it was first cultivated by the Aztecs for both medicinal and nutritional purposes, particularly valuing its tuberous roots. These early uses highlight the flower’s practical importance long before its ornamental appeal gained fame.
In the 18th century, Spanish botanists brought dahlias to Europe, where their vivid colours and intricate, layered petals quickly captured the hearts of horticulturists and gardeners alike. Dahlias belong to the Asteraceae family, which also includes familiar blooms like sunflowers and daisies.
Today, there are more than 40 recognized species and over 20,000 registered cultivars—each uniquely mesmerizing. With their increasing global appeal and deep cultural relevance, dahlias continue to flourish in gardens and celebrations around the world.
Bloom Season Across Indian Climates
In India, the dahlia season typically begins in the latter half of winter, particularly in the northern regions, and extends into early spring. The blooming period usually spans from January to March, with flowers often lingering into April depending on the climate. In hilly areas, dahlias may bloom as late as May, benefiting from cooler temperatures.
This long blooming window makes dahlias especially valuable for seasonal festivities such as Makar Sankranti, Vasant Panchami, and Holi, where their vibrant colours add beauty to traditional floral décor.
For successful growth, dahlias should be planted between October and November, giving their tubers ample time to establish roots before the onset of winter. By January, the plants begin to flower, continuing their display for several months.
Even novice gardeners can grow dahlias with basic care, making them a popular choice in both urban balconies and rural gardens. Their seasonal availability aligns perfectly with India’s cultural calendar, enhancing their appeal for ceremonial, decorative, and home gardening purposes.
Understanding Dahlia Tubers
This section aims to provide an understanding of dahlia roots and tubers. The roots of dahlias are tuberous and function as subterranean storage organs. This behaviour is in contrast to the majority of plants, which develop primarily from their seeds. The tubers of the dahlia plant can store water and nutrients, allowing the plant to survive periods of dormancy and re-sprout each year. Once the growing season concludes, Trim the plant so that it is three to four inches above the ground. Dig up the tubers in a gentle manner. Remove the soil and allow it to air dry for a minimum of a few days. Put the item in a cold, dark spot and store it in peat moss or sawdust. This procedure helps to maintain the vitality of dahlias for the subsequent growing season, resulting in them being both cost-effective and environmentally friendly.
From Tuber to Triumph: Cultivating Dahlia the Right Way
Growing dahlias from either tubers or seeds is reasonably straightforward, making them an excellent choice for inexperienced gardeners who are on a budget. Growing dahlias from seeds offers you the possibility of experimenting with novel hybrids, although tubers are now the most reliable and efficient method of cultivation.

Where should you cut a dahlia flower for harvesting or pruning?
To maximize stem length and encourage future blooms, cut dahlias just above a leaf node—the spot where leaves emerge from the stem. This promotes new shoot growth from the node and helps the plant produce longer, stronger stems in the future.
What is the difference between dahlias and chrysanthemums?
Dahlias and chrysanthemums, both belong from the Asteraceae family and are often confused due to their similar shapes and colour of palettes. However, they have distinct characteristics. Dahlias, native to Mexico, offer a broader variety of shapes and sizes—like pompon, cactus, and ball forms—while chrysanthemums, native to East Asia, are valued for their medicinal uses and resilience.
