Sunflower: The Summer Plant with Tasty Seeds

The sunflower always brings joy with its bright yellow petals. Besides, it produces tasty and nutritious edible seeds. Keep on reading to get acquainted with this beautiful plant.


Sunflower Plant

Helianthus is a genus comprising about 70 species of annual and perennial flowering plants in the daisy family Asteraceae.

The sunflower, also known as Helianthus annuus, is an annual plant that is native to North America, although it is usually associated with the Mediterranean area.

The scientific name of sunflowers is derived from Greek words helios, which means “sun”, and anthos, meaning “flower”.

You might be wondering why the name of this plant is sunflower. It happens because the head always follows the sun.

Therefore, if you are eager to grow it to enjoy the blooms, never put it on an east or west axis. Otherwise, you will only look at the back of it throughout the day.

This flower is renowned for its sunny short yellow petals that surround a darker central disk. However, it comes in a wide array of colors now, such as deep burgundy, chocolate browns, orange, maroon, and multicolor.

The sunflower is a fast-growing plant that blooms from mid-summer to early fall. It has one sturdy stem that can grow up to more than 10 feet, and hold single or multi-branched flowers.

People usually grow sunflowers for not only their beauty but also their edible seeds, which are favored by birds. You can also eat them raw for a quick snack, turn them into cooking oil or use them as livestock feed.

Sunflower Seeds

The sunflower seed is the fruit of the sunflower. There are three types of commonly used sunflower seeds: linoleic, high oleic, and sunflower oil seeds.

Sunflower crops consist of two main types. The first one is the seeds that you usually eat for snacks. Black-and-white striped shells, called hulls, encase a small edible seed inside.

It has a mild, nutty flavor with a firm texture when you touch it, and it becomes tender when you bite it. However, you cannot consume the shells.

The second type is the seeds that you can turn into oil. Unlike the other one, they feature solid black shells.

Making your own sunflower oil is not that hard. First, grind the oilseeds with a blender until they result in fine-meal consistency.

After that, roast it in the oven for 20 minutes. Set the temperature at 300-degrees Fahrenheit. Do not forget to stir it every five minutes.

If you do not replant the seeds right away, store them in an airtight container, and put it in a cool, dry place until you are ready to sow them.

Apply some fertilizer to encourage strong root growth that will protect the sunflower from being blown over by the wind.

Never add fertilizer to healthy soil since it can lead to an abundance of nitrogen, which makes the stems break or delays the bloom.
