Dahlias are perennials. They grow year after year without any special care required. You can plant them anywhere in your garden where they will not harm other plants or damage the soil. However, if you want to keep them from becoming invasive, then you need to give them some space when they have their first growth spurts.
There are two types of dahlias: those that bloom every spring and those that only bloom once a year. There are many varieties of each type, but the most common ones include Dahlia grandiflora (the famous one), Dahlia virginiana , and Dahlia californica . All these species produce white flowers with red centers.
The flowers are small, pale pinkish red, and very fragrant. They last just a few days before fading away completely. Their scent is so pungent that it attracts bees and butterflies which pollinate them.
These flowers are often used in perfumes and scented candles because of their sweet smell. If you live in a warm climate, you may wish to place a few dahlias near your door to deter the cold weather from getting inside!
It is not known exactly where dahlias come from. Some people think that they started in Mexico, while others believe that they originated in Peru or Chile. They have been grown and used for food and medicine in the Andes mountains for centuries before the Spanish conquest of the Incas and Aztecs.
When Hernan Cortez conquered Mexico in 1521, he brought the first dahlias back to Europe with him. They were a favorite of Empress Isabella of Spain because of their beauty.
In the wild, dahlias are perennial plants. They spread rapidly and can form large clumps if left unchecked. Even though they are native to warm, dry climates, they can be grown just about anywhere that has full sun.
They like sandy or gravelly soil, but they don’t care for compacted dirt and need good drainage. You can grow them in pots or window boxes quite successfully.
The tubers of the dahlia plant can be left in the ground over the winter and will bloom the following year. They are hardy enough to survive frosty nights as long as the ground hasn’t frozen solid. If you live in an area that has cold winters, dig up your tubers after the first frost and store them in a box of dry peat moss in a dark, cool place until spring.
Replant them a few weeks before the weather gets really warm.
Most dahlias are between 12 and 48 inches tall. The leaves are long and strap-like, growing up to 2 feet in length. The tubers can be small or weigh several pounds.
They are ovoid in shape and range in color from dark brown to beige. The tubers that grow on plants that bloom every year often produce smaller flowers than those that grow on plants that bloom every spring.
The dahlia, which is also known as the “king of the flowers,” is a popular garden plant that grows from a large tuber. There are many different kinds of dahlias that bloom in a whole rainbow of colors. Some grow only a few inches tall, while others are more than five feet in height.
Their petals range from white to yellow, orange, pink, purple, and even red. No matter what the variety, all dahlias have a similar appearance.
The dandelion is a familiar weed to most people. It grows almost anywhere in the world, even on the surface of Mars! It has jagged leaves and bright yellow flowers that turn into fluffy clouds of parachutes that look like mice riding balloons.
They are especially fun to blow away on a windy day!
