There be giants in the land!
When I was growing up in Central Texas, my friends and I would often begin the summer exploring the dense forests of sunflowers that grew in open fields near our homes. To adventurous and highly imaginative ten and eleven year olds, the sunflowers would transform into a variety of interesting and often dangerous creatures.
To the unsuspecting adult these 8 foot giants seemed innocent enough with their huge yellow blooms smiling at the sun, but us kids who belonged to the secret "Space Rangers" unit knew better. These innocent looking lanky spiny creatures were aliens from outer space, and the "Space Rangers" were charged with saving the Earth from their spreading invasion.
I must confess that we slew many of these creatures with our “laser swords”, before we were duly informed by “higher parental command" that the sunflowers were not aliens and should be left to live out their normal lives as Texas wildflowers. Today when I see a field of sunflowers (see panorama of large field of sunflowers), I smile and remember the many summers of fun we had running through their jungle populations.
The sunflower is a true native of the Americas and has been regarded as a useful plant for over 3,000 years (recent evidence points to an even longer time). Many Native American tribes sought to cultivate the sunflower for a variety of purposes. Over fifteen tribes used various parts of the sunflowers for food, medicine and a source of oil. The seeds were thought to provide an immediate source of energy for war or hunting parties to overcome fatigue. Dyes were extracted from the seed heads of the sunflowers and the blooms were used as decorations.
Early American colonists virtually ignored the benefits of the sunflowers, but the seeds found their way to Russia where the sunflower was botanically enhanced producing the Mammoth Russian sunflower. The enhanced seeds were reintroduced into America in 1883. Presently in the former Soviet Union countries, the seed hulls are also used in the production of ethyl alcohol as a source of fuel.
Today the sunflower is a major horticultural and agricultural product in the USA. Sunflowers are grown for their seeds as food product, as a source of cooking oil, and as a food source for farm animals. The sunflower kernel reportedly is high in vitamin E, Zinc, selenium, folate, iron, vitamin B6 and pantothenic acid.
According to the National Sunflower Association, 90% of the fat in the kernel is monounsaturated and polyunsaturated fat which are the "good fats" containing the beneficial “high density lipoprotein (HDL) cholesterol" which is needed to help carry away the bad cholesterol in the blood.
Other species in Texas include the ashy sunflower (Helianthus mollis) and the Maximilian sunflower (Helianthus maximiliani). The Maximilian sunflower blooms primarily in August to October providing tall trestle like stalks covered with large yellow blooms. The bloom of the Maximilian is dainty, but very expressive in beauty (see photo). In March of 2016, I came across what at first appeared to be a very early sunflower bloom. After some searching and verification, I discovered it was a Texas sunflower, (Helianthus praecox) – (see photo)
If you have the room in your garden then I highly recommend planting the sunflower, especially the Maximillian species. Seeds can be obtained from Native American Seed or Wildseed Farms. The sunflower will add beauty to your garden, attract bees and butterflies and provide a good food source for seed-eating birds.
- Iowa lists the wild sunflower, Helianthus annuus as a secondary noxious weed, so it might be advisable to consult the ISU Extension Agronomy office in Iowa before planting sunflowers in farm or pasture lands.
- The sunflower is the state flower of Kansas where supposedly you can still find fields of it in bloom in September.
- The florets of the sunflower form a Fermat's spiral.
