This flower (Taraxacum officinale) is found worldwide. And, as many a child discovers to their delight, when a dandelion sets seed, the flower (actually, hundreds of tiny florets) turns into a mass of seeds known as a dandelion clock.
LIFE CYCLE OF A DANDELION
Dandelions can bloom for extended periods of time but are most visible in May and June. The florets develop from the center, blooming into a circular flower head. After flowering for a couple of days, the flower head closes and the seeds develop inside the closed head.
The 3 phases of a dandelion represent the sun, moon and stars. The yellow flower represents the sun, the white puff ball represents the moon and the dispersing seeds represent the stars.
Each flower is also encased in those white fibres that will eventually form a fluffy white head - but you can't see them clearly when a dandelion is in full bloom.
Once pollination by bees or other insects has taken place, each fertilized floret produces a seed called an achene. Each seed pushes up through the floret and develops a feathery filament called a pappus. When viewed collectively on the dandelion's seed head, the filaments look like a white puff ball.
Each seed is attached to a characteristic fuzzy structure called a 'pappus' that allows the seed to be carried by the wind.
Eventually, all those beautiful flowers eventually turn to white globes of exposed seeds that are often called "puffballs." Dandelions grow so successfully because those puffballs disperse their seeds over long distances in a stiff breeze.
Eventually, all those beautiful flowers turn into white globes of exposed seeds that are often called "puffballs."
It turns out that fluid isn't sap or poison, but a defense mechanism, in the form of latex! The Lithuanian word for dandelions is 'pienė', which literally translates to milky, for the white liquid. Latex is produced by cells called laticifers, which exist in more than 20 000 plant species, as well as some fungi.
The French have another name for them — "pee the bed"
The French word [for dandelion] is pissenlit, which translates to "pee the bed." Dandelions are a diuretic and in fact they are as strong as some of the commercial products.
Life Cycle: Dandelions grow from seeds and do not spread asexually from stolons or runner; they have a single tap root. However, they can and do reproduce asexually by seed. They are capable of producing viable seed without need of cross-fertilization, a process known as "apomixis".
Dandelions are edible and nontoxic for dogs; however, some parts of the plant are more nutritious than others. Here are three of the most nutrient-dense parts of dandelions: Blooms: Dogs can consume the yellow flowers or seed puffs of dandelions. Dandelion blooms contain high levels of antioxidants and polyphenols.
The dandelion (Taraxacum officinale) is an abundant “weed” plant that also happens to be edible. In fact, nearly the entire plant can be consumed in one way or another. The only inedible part is the stem, which contains a very bitter, milky substance.
Dandelions are both male and female at the same time. For most hermaphroditic flowers, the genders develop at slightly different times to avoid inbreeding. Inbreeding allows negative traits that are normally recessive to become physical traits, which isn't good.
It's been said that if you can blow all the seeds off a dandelion with a single breath, then the person you love will love you back. If seeds remain, then the object of your affection may have reservations about their feelings toward you.
The genus is native to Eurasia and North America, but the two most commonplace species worldwide, T. officinale (the common dandelion) and T. erythrospermum (the red-seeded dandelion), were introduced from Europe into North America, where they now propagate as wildflowers. Both species are edible in their entirety.
In folk medicine, dandelion is referred to as the elixir of life because it purifies the body of residues and negative energies. Because of its cleansing effect, it is also called blood purifier, laxative agent, liver cleanser and fatigue remover.
Some may also think of dandelions as those white puffballs whose seeds you can blow away like a candle on a birthday cake. The puffball is also considered a dandelion — it's what the yellow flower matures into after a few days.
Every part of the dandelion plant is edible and packed with nutrients.
Yellow flower of the plant becomes a puff ball which comprises many fruits known as achenes.
The leaves are used to stimulate the appetite and help digestion. Dandelion flower has antioxidant properties. Dandelion may also help improve the immune system. Herbalists use dandelion root to detoxify the liver and gallbladder, and dandelion leaves to help kidney function.
Dandelions have been called lion's-tooth, cankerwort, Irish daisy, monk's-head, priest's-crown, puffball, blowball, and milk-, witch-, or yellow-gowan (3).
You can see in the photos above and the video below, that there is a layer of air around the dandelion which protects it from the water. This is because each of the dandelion seeds is attached to a pappus, which is a parachute-like structure made of around 100 fine bristles, and this structure is mostly air (92% air!).
A few years ago I started work in a lab studying a strange group of animals called siphonophores that includes the Portuguese man-of-war. Turns out the ocean dandelion is a siphonophore, and these siphonophores challenge a simple assumption about what it means to be an animal.
Cat's Ear (Hypochaeris radicata) is the most likely to be mistaken for dandelion, as the flower heads look very similar. Cat's Ear do not have hollow stems and their stems are branching. They also have hairy leaves with deep notches.
