Abstract

This document provides an overview of the German violet (Exacum affine), a 6 to 12 inch tall annual known for its blue flowers and shiny green foliage. It details the plant’s characteristics, including its dense, rounded habit, slow growth rate, and fine texture. The German violet thrives in partial shade with well-drained, light soil, and requires moderate fertilization and watering. It is not native to North America and is somewhat available, though it may require sourcing from outside the region. The document also highlights potential issues such as gray mold and broad mites, and offers guidance on propagation by seed. Original publication date October 1999.
