Dandelion
From Tardis Wiki, the free Doctor Who reference
Dandelions were Earth flowers.
One was supposed to be able to tell time by counting how many puffs it takes to blow all seeds, called filamentous achenes, off a dandelion clock. In 2016, Tanya Adeola discovered that this method did not work.
The female bone spider added homing devices to filamentous achenes to bring her daughter back. This resulted in attracting Tanya and Amira to Alice Parsons' house instead. (PROSE: The Stone House)
