Morina longifolia

Morina longifolia, or whorlflower, is an evergreen perennial in the honeysuckle family, Caprifoliaceae. Its native range runs from northern Pakistan through the Himalaya to southern Tibet. It grows on open slopes and among alpine shrubs. These sites lie at 9,840–13,120 feet [3,000–4,000 metres] above sea level. Its native climate is subalpine or subarctic. It is not native to Britain or Ireland.

The plant forms a compact rosette with a bushy outline. Its glossy leaves have a lance shape and spiny edges. Each leaf can reach about 1 foot [0.3 metres] long. Garden plants reach 1.6–3.3 feet [0.5–1 metre] tall. Their spread ranges from 0.3–1.6 feet [0.1–0.5 metres]. They take two to five years to reach full size. Flowers open in midsummer and measure about 0.1 foot [0.03 metres] long. They start white, turn pink, then deepen to crimson. The changing colours add interest as the blooms age.

Give this plant full sun and poor soil that drains well. Protect it from wet ground in winter. The RHS lists chalk, loam and sand as suitable soils. It accepts acid, neutral and alkaline conditions. South-facing and west-facing sites suit it, with or without shelter. The RHS rates its hardiness as H6. Chicago Botanic Garden lists USDA zones 6–8. Roots dislike disturbance, so avoid needless moves. Sow ripe seed in a cold frame, using gritty compost. Place each seed in its own pot. Winter root cuttings offer another way to raise plants.

Whorlflower suits gravel gardens, rock gardens, beds and borders. It also fits cottage gardens, courtyards and coastal sites. Its evergreen rosette gives these plantings foliage through winter. The seedheads can go into dried flower arrangements. Slugs and snails may attack the plant. Rot is another risk, with shade making trouble more likely. Plants For A Future does not flag it as weedy.

Plants For A Future lists no known edible uses or hazards. This does not establish that the plant is safe to eat. It records stems, leaves and flowers in Tibetan medicine for stomach complaints. Those uses include aiding digestion and inducing vomiting. These records describe traditional use, not proven treatment. The plant also serves as incense. Its roots yield an essential oil.
