Proplifting is the practice of taking discarded plant material and propagating new plants from them. Some proplifters engage with the hobby as a form of self-administered horticultural therapy.

Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago.
