Summary

Gentiana punctata, the spotted gentian, is a least concern herbaceous species of flowering plant in the gentian family Gentianaceae. It grows in Central and Southeastern Europe at altitudes 1.500−2.600 meters. It is 20−60 cm tall.

Description

A small plant. It grows 60 cm high and spreads 30 cm wide. There are a clump of leaves at the base. There is a stout taproot which develops an upright stem. The leaves at the base are 10 cm long and the leaves on the stem are smaller. The flowers occur in clusters at the tips of stems and in the axils of leaves. They are pale yellow with purple spots. They are 30 mm long.

Edible Uses

The root is sometimes used in the manufacture of gentian bitters.

Traditional Uses

Medicinal Uses

This species is among several that serve as sources of medicinal gentian root; the thick rootstock can reach up to 1 metre in length. The following notes reflect the general uses of G. lutea, the most commonly used species in the West. Gentian root has a long history as a herbal bitter in the treatment of digestive disorders and is an ingredient in many proprietary medicines. It contains some of the most bitter compounds known and serves as a scientific benchmark for measuring bitterness. It is especially useful in states of exhaustion from chronic disease and in cases of debility, weakness of the digestive system, and poor appetite. It is one of the finest strengtheners of the human system, stimulating the liver, gall bladder, and digestive system, and combines well with a purgative to offset that treatment's debilitating effects. The root is anthelmintic, anti-inflammatory, antiseptic, bitter tonic, cholagogue, emmenagogue, febrifuge, refrigerant, and stomachic. Taken internally, it treats liver complaints, indigestion, gastric infections, and anorexia. It should not be prescribed for patients with gastric or duodenal ulcers. The root is harvested in autumn and dried for later use. Roots from plants that have not yet flowered are thought to be the richest in medicinal properties.

Known Hazards

Should not be prescribed for patients with gastric or duodenal ulcers.

Distribution

It is a temperate plant. It grows in the high mountains in Europe. It suits hardiness zones 5-9.

Where It Grows

Australia, Austria, Balkans, Europe, France, Macedonia, Slovakia,

Cultivation

In general, gentians require a moist well-drained soil in a sheltered position, a certain minimum of atmospheric humidity, high light intensity but a site where temperatures are not too high. They are therefore more difficult to grow in areas with hot summers and in such a region they appreciate some protection from the strongest sunlight. Most species will grow well in the rock garden. This species is not particular about soil type, so long as it is deep enough to accommodate the plant's roots. A moisture loving plant, preferring to grow with full exposure to the sun but with plenty of underground moisture in the summer, it grows better in the north and west of Britain. Plants are intolerant of root disturbance.

Propagation

Seed is best sown as soon as it is ripe in a light position in a cold frame. It can also be sown in late winter or early spring, though germination is best after a period of cold stratification; stored seed loses viability quickly, with older seed germinating slowly and erratically. Keeping seed at around 10°c for a few days after sowing allows it to absorb moisture. Following this with at least 5–6 weeks of temperatures between 0 and -5°c will usually produce reasonable germination. Clay pots are preferable to plastic, as plastic drains less freely and the resulting moisture encourages moss growth that can prevent germination. Sow seed on the surface or cover with only the lightest dressing of compost. Seed requires darkness to germinate, so cover pots with newspaper or keep them in the dark. Pot seedlings into individual pots as soon as they are large enough to handle, and grow on in light shade in the greenhouse for at least their first winter. Seedlings are slow-growing, taking 2–7 years to reach flowering size. Move plants to their permanent positions in late spring or early summer once large enough. Division in March is possible, though most members of this genus have either a single tap-root or a compact root system united in a single root head, making them generally unsuitable for division. Basal shoot cuttings can be taken in late spring.

Other Uses

None known.
