Gentian

RHS Genus Guide

Gentians are an iconic group, best known for their classic alpines with intensely blue flowers. However, the trumpet-shaped blooms also come in white and even yellow, and there are several taller species that extend their value in the garden. The alpines love a sunny rock garden or container-based display, whereas taller, late-flowering willow gentian thrives in a border with dappled shade.
