Classification of Common Sunflowers
Types of Sunflowers
When you think of sunflowers, you might think of the classic yellow bloom with a deep brown centre. This type of sunflower is just one out of over 70 types of sunflowers. These blooms fit into one of three categories, giant sunflowers, dwarf sunflowers, and colourful sunflowers.
How Did Sunflowers Get Their Name?
The name "sunflower" is a direct reflection of the way these blooms reposition themselves to face the sun throughout the day. This phenomenon of "chasing the sun" and following its pattern from sunrise to sunset is referred to as heliotropism. While the Greek words "Helios" and "Anthos" translate to sun and flower, it makes sense that the genus of the sunflower is Helianthus.
To explain why sunflowers, especially young blooms, have a circadian rhythm to support the heliotropism behaviour, the ancient Greeks turned to the legend of Apollo, the god of sun and light, and Clytie, a water nymph. Clytie was deeply in love with Apollo, and while he loved her back at first, Apollo soon fell in love with Leucothoe. In jealousy, Clytie went to Leucothoe's father who disapproved of his daughter's relationship with Apollo and buried her alive as punishment. Outraged and grieving, Apollo turned Clytie into a sunflower. As such, she spent all of her days still in love, watching the sun as Apollo moved it across the sky every day in his chariot, identical to the way young sunflowers follow the sun across the sky today.
History of Sunflowers
Native to America, the sunflower's origin begins in the western region of the United States around 1000 BC, when wild sunflower plants became domesticated and harvested for their seeds. Over 8,000 years ago, Native Americans cultivated sunflowers as a source of food and medicine to treat wounds, kidney, and chest pains. While they are no longer used for medicinal purposes, sunflowers are now harvested all across the planet and their seeds are still enjoyed by many. The oils of sunflowers are also utilized for beauty products and cooking. Today, North Dakota remains the leader in growing sunflowers due to its optimal soil conditions, water, and climate.

Caring for Outdoor Sunflowers
As their name suggests, sunflowers grow best in full direct sunlight, preferably soaking up rays for no less than six to eight hours per day. If you are able to control the air temperature around them, sunflowers thrive in low to high 70 degrees, although adult sunflowers are drought-tolerant and can withstand higher temperatures under the hot summer heat. The best soil for sunflowers has a pH level between 6 and 7.5 and is light and fluffy so their roots can easily spread out. Adding liquid fertilizer and organic materials into your soil is a wonderful way to ensure your sunflowers have an adequate food supply. You will know your sunflower is ready for harvest when the back of its head turns a nice shade of brown.
Pro tip: It is best to clip sunflowers from your garden in the afternoon before bringing them inside to display in a vase.

Cut sunflowers can last in a vase for about seven to ten days. The best practices for caring for your sunflowers include:
- Removing any foliage that falls below the waterline in your vase
