A family of plants is a scientific grouping used to describe plants that share certain characteristics. As a gardener, knowing which family a vegetable plant belongs to can be very helpful because the conditions needed for optimum growth, nutrients absorbed, and care required for plants in a particular family are usually similar.
Knowing which family your vegetable plants belong to can help you choose the best companion plants, cover crops, and help identify which plants should be grown in succession for crop rotation in your vegetable garden.
