Can a plant keep producing bud if it is kept in flowering?

[yabatab]

orange and RX are both right it is an annual plant in its natural environment
but if grown indoors the plant can live on after the flowering cycle. After
the fist full flowering stage inside the plant will produce lower qaulity buds
as RX said. I have also tried that its not worth doing but the plant will live
on in a controled environment.
