Gentiana (Gentian)
Prized by rock garden enthusiasts, Gentians are strikingly beautiful perennials, native to the temperate and arctic regions of the world. When in full bloom, they are hard to beat in terms of floral display with their profusion of intense blue flowers. Mostly evergreen or herbaceous perennials, they bloom in late spring or late summer and are glorious subjects for rock gardens, raised beds or garden edging.
