are there flowers of different species that are found to always or usually grow together?

Question

is there a flower that always grows beside a specific flower?

Answer 1

You'll often get close ecological associations that can be very strong if the habitat is extreme or isolated. For example, plants in salt water marshes like Spartina and Salicornia usually grow together.

Other examples are parasitic, hemiparasitic, or mycotrophic plants that have preferred hosts. For example, if you spot a Sarcodes (snow plant) then it will always be near Abies magnifica (fir tree) because of its association with the mycorrhizae specific to the fir.
