There are various divisions of horticulture because plants are grown for a variety of purposes.

Roderick Leon Bieleski was a New Zealand plant physiologist. As a botanist and horticulturist, his research focussed on understanding the factors that affected the behaviour of plants, in particular horticultural crops. His work had practical relevance to farmers and orchardists in building their understanding of these factors and taking account of them while making a living from growing and harvesting plants. He received many honours and awards, culminating in being appointed Member of the New Zealand Order of Merit (MNZM) in 2010.
