St John's wort reproduces both [[Vegetative reproduction|vegetatively]] and [[Sexual reproduction|sexually]]. Depending on environmental and climatic conditions, and the age of the plant, St John's wort will alter the way it grows to promote survival. Summer rains are particularly effective in allowing the plant to grow vegetatively, following [[defoliation]] by insects or grazing.<ref name="BioactiveMolecules">Ramawat, Kishan Gopal.
