I don't know if the term is used elsewhere in the world but here in the UK the seed head of the common weed Dandelion is known as the Dandelion Clock. As kids it was said that the number of puffs required to blow all the seeds off would indicate the time of day. This one is hanging on to the last of the morning dew, hence the title.
