Key Plant Families and Their Diagnostic Features

Recognize plants at the family level — the single most useful skill in field identification

Twelve lessons on identifying plants at the botanical family level using diagnostic characters you can see in the field. You will learn the dozen most relevant families for medicinal plant work, the specific features that identify each, and how to predict medicinal action and safety patterns from family-level identification.

Taught by Deidre Starner, Master Herbalist

What you'll learn

  • Identify the major medicinal plant families (Lamiaceae, Asteraceae, Apiaceae, Rosaceae, Fabaceae, others) from diagnostic features in the field
  • Predict general medicinal action patterns from family identification
  • Recognize safety-relevant family features (notably the dangerous Apiaceae members)
  • Use a botanical key to confirm family-level identification
  • Document plant observations with the field detail needed for confident identification
