What does Gentian sage look like?
Gentian sage is a perennial with tuberous roots and grows to about 30 to 60 cm in height and width. Its leaves are shaped like arrowheads and have a soft green color. The flower stems rise above the leaves, holding spaced-out, vivid blue flowers about 2.6 cm long, each with a small green cup at the base. Some cultivated forms can reach up to 1.8 meters and have larger, deep blue blooms.
Where does Gentian sage come from?
This sage species grows wild in central Mexico. It was first brought into gardens in 1838. William Robinson, an Irish gardener and botanist, helped make it popular in the early 20th century. Plant explorers have since found taller and larger-flowered forms in Mexico, and breeders in the Netherlands have developed new color varieties.
When and how Gentian sage blooms
Gentian sage is usually planted in spring after frost has passed. Because it does not survive hard freezes, gardeners often treat it as an annual or lift the tubers to store indoors over winter. It grows from seed or tubers and prefers mild conditions. Flower colors now include blue, white, and lilac, thanks to selective breeding.
