dandelion: [13] Dandelion means literally ‘lion’s tooth’. It was borrowed from French dent-de-lion, which itself was a translation of medieval Latin dēns leōnis. It was presumably so called from the toothlike points of its leaves (although some have speculated that the name comes from the long taproot). The plant has a variety of local dialectal names, many of them (clock, farmer’s clocks, schoolboy’s clock, telltime, time flower) reflecting the traditional practice of telling the time by blowing off all the plant’s tufted seeds (the number of puffs needed indicates the hour). Piss-a-bed, like its French counterpart pissenlit, betrays the plant’s diuretic properties.

dandelion (n.)youdaoicibaDictYouDict
early 15c., earlier dent-de-lioun (late 14c.), from Middle French dent de lion, literally "lion's tooth" (from its toothed leaves), translation of Medieval Latin dens leonis. Other folk names, like tell-time refer to the custom of telling the time by blowing the white seed (the number of puffs required to blow them all off supposedly being the number of the hour), or to the plant's more authentic diuretic qualities, preserved in Middle English piss-a-bed and French pissenlit.
