When does the caper flower bloom?

In reviewing several sources I was able to determine the following:

Capers are perennial, meaning they will bloom all year depending on environment.

Only mature plants bloom.

Mature in this case is defined as one to four years, depending which reference you go by.

So if you plant now, you may see blooms in as little as a year, or as much as four.

This also depends on which species of caper you are referring to. here are a few of the estimated 350 species, the list includes common names, and for some countries of cultivation, or where found naturally.
