This page facilitates viewing horticultural images by plant family and covers the families starting with the letters A–D. Knowing the family that a plant belongs to provides insights into its evolution and is often a very good guide to its cultivation. Also, narrowing a plant search down to a family is often the first step to plant identification and classification. That's why being able to spot key family traits is so important when identifying unknown plants and allowing botanists to determine a classification. This page is arranged alphabetically but it also possible to view the families by taxonomic hierarchy. There is also a Botanical Glossary to explain technical terms.
