This flower is a perfect time to play," He loves me, he loves me not."
The idea is similar to plucking a petal of a daisy flower.
With
the dandelion flower, you blow with one breathe. If the seeds get blown
away a lot, you know he loves you a lot. But if a lot of the seeds
remain, you know he couldn't care the stuff about you.
Of course, the seeds will naturely blow away as long as you choose a mature flower and you blow with a lung full of air.
Another folklore of the dandelion:
Dandelion Thoughts
Folklore
says that blowing the seeds off a dandelion is said to carry your
thoughts and dreams to your loved one. At least, so they say... Source:

"Are you separated from the object of your
love? Carefully pluck one of the feathery heads; charge each of the
little feathers composing it with a tender thought; turn towards the
spot where the loved one dwells; blow, and the seed-ball will convey
your message faithfully. Do you wish to know if that dear one is
thinking of you? blow again; and if there be left upon the stalk a
single aigrette, it is a proof you are not forgotten. Similarly, the
dandelion is consulted as to whether the lover lives east, west, north,
or south, and whether he is coming or not." Source: "The Child and
Childhood in Folk-Thought," by Alexander F. Chamberlain
I should go to the garden and blow a lot of dandelion and think of my poor D alone in Singapore at this festive season.
The dandelion flower leaves behind a long stalk.

Insecticidal / Poison / Rotenone:
(1) Roots are insecticidal; rotenone from
roots is raw material for insecticides against plant pests.
(2) Since early times, the root has been used as fish poison in the
Philippines, the Dutch East Indies, and the Malay Peninsula. The Chinese
and Malay gardeners have used the root decoction as an insecticide. (3)
Rotenone has also been found effective against plant lice, leaf
beetles, aphids, flies, caterpillars, ticks, chicken lice, red spiders
and other insects. (4) It has been reported to be more effective than
potassium cyanide or nicotine and equally effective as pyrethrum. (5) In
the Philippines, cattle have been reported to die after eating the
leaves. (6) Humans have been reported to use it for suicide and murder.
(7) Because of toxicity, rotenone as insecticidal is being phased out in
many eco-conscious countries.
