Expected reproduction rate of a dandelion and/or fern
Dandelions may have "from 54 to 172 seeds per head and a single plant can produce more than 2000 seeds" (https://fyi.uwex.edu/weedsci/2002/11/12/dandelion/), but the number of inflorescences depends, for example, on the age of the plant. It should also be remembered that some individuals repeat the blooming in autumn, although it is not so abundant (usually only one inflorescence). That, what is called a dandelion (Taraxacum officinale) is a collective species, which actually consists of several hundred microspecies, which may differ in the amount of seeds produced. Thus, the given data is only quoted.
