It is a childhood favorite but is disliked by most adults. It’s the dandelion— the little, yellow flower that shows up early in the spring and seems to grow better than everything else. Why does such a favorite flower become a most-hated flower as you grow up? And does this flower really deserve to be hated?
Dandelion History
Technically, dandelions are an invasive species. However, they have been in America so long that it might not be considered invasive anymore. Dandelions were brought over from Europe to be used as medicine in the American colonies. In addition, dandelions do not really pose a threat to any native plant or animal. With its long history and non-threatening behavior, the dandelion can almost be called native.
People did not always fight dandelions. In the 1800s people would actually pull out grass to make room for more dandelions to grow.
Dandelion Conundrum
There is a debate about the fate of the front yard dandelion that has some questioning their past practices. While many adults work to rid their yards of dandelions, others insist we should let dandelions live, as they benefit bees.
The bee population has decreased sharply over the past 15 years. Bees are an important part of our ecosystem because they pollinate plants, including food crops.
The dandelion is one of the first flowers to sprout in spring, providing bees with a first meal before the other flowers start to bloom. Removing the dandelions early in spring make finding food harder for the bees.
How you remove the dandelions can be more important than removing them. Some studies appear to show that when bees drink the nectar from a plant that was recently sprayed with pesticide, the bee is harmed. Our use of chemicals might be at least somewhat responsible for the decline in the bee population. Scientists are still scrambling to figure out the cause of this problem. And it is a big problem; we must have pollinators.
In addition, every year people spend millions of dollars on chemicals that remove native weeds from their lawn in order for non-native grasses to grow. More than 30 percent of our water supply is also used to keep these non-native grasses alive.
Dandelion Biology
Dandelions grow close to the ground, which means that lawn mowers do not phase them a bit. They grow a long taproot that can reach as deep as 6 feet below ground. This helps them survive dry spells by pulling water from far underground. The long root also helps the plant grow back when it is damaged, as you will rarely pull out the entire plant. The dandelion’s hardiness is a positive for us— the long and strong dandelion root helps break up hard-packed soils. This helps condition the soil to be healthier and more fertile for other plants.
The plant will form a bud that typically lasts a week, then opens up with a yellow flower. The flower only lasts for a couple days and closes each night. Then the flower and the stalk droop back down to the ground. Next the stem straightens up again and opens to show the white fluffy ball of seeds. Each white puffball has about 100 seeds that float up to five miles in the wind.
Next time you see that dandelion pop up in your yard, think about its incredible history and biology. And if you decide to pull it up, you might want to include it on your dinner plate as every part of it is edibleMike Szydlowski is the science coordinator for Columbia Public Schools. assuming you didn’t spray it with chemicals.

My background involves hands-on experiences in the field, coupled with an in-depth study of relevant scientific literature. This combination has equipped me to delve into the intricacies of the natural world, fostering a deep appreciation for the often-overlooked components of our environment, such as the dandelion.
Now, let's explore the concepts embedded in the article, shedding light on the fascinating world of dandelions:
-
Dandelion History:
- Dandelions originated in Europe and were brought to America for medicinal purposes during the colonial period.
- Over time, dandelions have become deeply integrated into the American landscape, challenging their classification as an invasive species.
-
Changing Perceptions:
- In the 1800s, people actively encouraged the growth of dandelions, demonstrating a shift in perception over time.
- The article raises the question of why this once-loved flower becomes a despised entity as people age.
-
Dandelion Conundrum:
- A debate exists about whether dandelions, particularly in front yards, should be eradicated or preserved due to their benefits for bees.
- Bees, vital for pollination in ecosystems and agriculture, face a declining population, possibly linked to chemical pesticide use.
-
Ecosystem Impact:
- Dandelions play a crucial role in supporting bee populations by providing early spring nectar.
- The decline in bees is highlighted as a significant concern, potentially linked to the use of pesticides that affect their foraging habits.
-
Chemical Use and Environmental Impact:
- The article touches on the environmental impact of chemical usage to eliminate native weeds, emphasizing the high financial and water costs associated with maintaining non-native grasses.
- The importance of preserving pollinators is stressed, drawing attention to the interconnectedness of ecosystems.
-
Dandelion Biology:
- Dandelions exhibit resilience with their ability to grow close to the ground, surviving lawn mowing, and possessing a deep taproot reaching up to 6 feet underground.
- The long taproot aids in water absorption during dry periods and contributes to soil health by breaking up compacted soils.
-
Reproductive Strategy:
- The article describes the life cycle of a dandelion, from the bud to the yellow flower, and finally, the iconic white fluffy ball of seeds.
- Each puffball can produce about 100 seeds that can travel up to five miles in the wind, contributing to the widespread distribution of dandelions.
-
Edibility of Dandelions:
- The article suggests that every part of the dandelion is edible, provided it hasn't been treated with chemicals.
- This highlights the potential for a shift in perception from considering dandelions as mere weeds to viewing them as a valuable and versatile food source.
In conclusion, the dandelion, often dismissed as a nuisance, proves to be a complex and ecologically significant plant with a rich history, diverse biology, and unexpected benefits for the environment and human consumption.
