Gentian - Plant
Description for Gentian
They are symbols for alpine flora and as most hail from mountainous regions, they are ideal subjects for the rock garden.
Gentiana is a genus of flowering plants belonging to the gentian family, the tribe Gentianeae, and the monophyletic subtribe Gentianinae. With about 400 species it is considered a large genus.
The ultimate example of their alpine nature is the fact that gentians grow on the slopes of Mt. Everest at an elevation of 18,000 feet! As a genus, they are indeed primarily alpine in nature, occurring in the mountains of western North America, Europe, Andes, Himalayas and Australia/New Zealand. However, with well over 200 species, there are actually some gentians which are better suited for the perennial border or woodland garden.
They range from just a few centimeters to giants up to 2 m. The predominant colour is blue, but they do come in white, yellow, purple, red and even green. Strangely, while blue is the dominant colour, those which hail from Australia/ New Zealand are almost all white-flowered! Their trumpet-like flowers are primarily adapted to pollination by bees, which, as a rule, are attracted to blue flowers.

Planting and care
It is probably easiest to grow Gentiana species such as Gentian from plants purchased from garden centres; even then these are not the easiest of plants to grow.
Once you have Gentiana seedlings transplant them into the garden in the autumn or spring at a spacing of 15 to 30 cm (most Gentiana varieties) or about 50cm if you are growing one of the taller Gentiana species.
|Part shade||well-drained soil||Medium||20 to 25 degrees||Apply any organic fertilizer|
Caring for Gentian
- Not the easiest species to grow or look after, Gentiana requires a moist soil, so water regularly but do not drench the plants; never disturb the roots or move the plants during the growing season.
If you require more Gentiana plants it is best to purchase them from a garden centre; or very carefully propagate Gentiana by division once they have finished blooming.
