The plant family Papaveraceae was named and described by Antoine Laurent de Jussieu in Genera Plantarum in 1789.
As of 12-8-21 when this page was last updated, Plants of the World Online lists 42 genera in this family commonly referred to as the poppy family. The is a family mostly of herbaceous plants (annuals, biennials, and perennials) but also includes a few trees and shrubs.
I only have experience with Lamprocapnos spectabilis (Bleeding Heart) in this family. You can click on the name to go to its own page.
