Gentiana kurroo aka Himalayan Gentian

Gentiana kurroo is a small plant that lives for years. It belongs to the gentian family, Gentianaceae. Its native range spans Afghanistan to the western Himalaya. Records place it in northern India and Pakistan too. It grows in a temperate climate. It is not native to Britain or Ireland. In the wild, it grows on grassy slopes. These lie about 5,900–8,860 feet [1,800–2,700 metres] above sea level. These mountain sites help explain its needs in gardens.

Plants reach about 0.7 feet [0.2 metres] in height. This low size suits a place in garden beds. Flowers bloom from August to September, late in the growing season. Each flower has both male and female organs. Bumblebees and butterflies carry pollen between the flowers. The supplied species records do not state the flower colour. They give no details of fruit, leaf shape or stem shape. Flower traits of the whole genus cannot fill these gaps for this species.

This plant needs moist soil that lets water drain freely. PFAF lists sand, loam and clay as suitable soils. Its detailed growing notes call for stony soil with good drainage. Soil type alone is thus not a useful guide to site choice. It accepts slightly acid, neutral and slightly alkaline soil. It can grow in sun or part shade. Keep it safe from too much wet in winter. PFAF lists USDA zones 6–9. Yet it also notes reports of poor hardiness in Britain. It suggests too much wet may cause more failures than cold. These needs make it important to choose the site with care.

You can raise new plants from seed. Sow fresh seed in a bright cold frame once it ripens. You can also sow in late winter or early spring. A cold treatment helps the seeds sprout. Stored seed soon loses its power to grow. Older seed may take longer to sprout, with uneven results. PFAF lists no edible use and gives an edibility score of zero. It reports no known hazards, but this does not prove safety. The root has a use in medicine. The supplied claims for wider treatments concern a different species. They do not show what effects this species has. PFAF records no other uses and does not flag weed potential.
