Cultivation Details

HabitPerennial
Growth—

Swertia species are generally plants of moderate to high elevations where they are often found on damp slopes and humus-rich, peat mosses. They grow best in areas with cool summers and perennial species are generally cold-hardy to temperatures down to around -15°c[1]. Swertia species generally grow well in humus-rich soils in damp, open woodland, by streams or in bog gardens[1].

Propagation

Seed - sow in trays in spring in a humus-rich medium in temperatures not exceeding 10°c[1]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in early summer. Division of large clumps in spring, taking care not to damage any taproots[1].
