Description

Bergenia Buy elephant39s ears Bergenia 39Overture39 Delivery by Crocus

They are clump-forming, rhizomatous, evergreen perennials with a spirally arranged rosette of leaves 6–35 cm long and 4–15 cm broad, and pink flowers produced in a cyme. The leaves are large, leathery, ovate or cordate, and often have wavy or saw-toothed edges. For most of the year, the leaves have a glossy green colour, but in cooler climates, they turn red or bronze in the fall. The flowers grow on a stem similar in colour to a rhubarb stalk and most varieties have cone-shaped flowers in varying shades of pink. These can range from almost white to ruby red and purple.

  • Bergenia ciliata, including the cultivar Bergenia ciliata 'Superba'
  • Bergenia crassifolia is the most widely grown garden plant, especially the cultivar Bergenia cordifolia 'Purpurea.' The species epithet cordifolia means cordate (heart-shaped) leaf. The leaves are winter hardy and change color in the range of rust brown to brown-red. Other cultivars are Bergenia cordifolia 'Winterglut' and Bergenia cordifolia 'Senior.'
  • Bergenia crassifolia is about 12 inches tall. The leaves are spoon-shaped. One cultivar is Bergenia crassifolia 'Autumn Red.'


  • Bergenia cordifolia
  • Bergenia emeiensis
  • Bergenia ligulata
  • Bergenia pacumbis
  • Bergenia purpurascens is 12-16 inches tall and has carmine-red flowers. The leaves are oval-shaped.
  • Bergenia purpurascens var. delavayi is ca. 20 inches tall with small leaves and rosy red flowers.
  • Bergenia scopulosa
  • Bergenia stracheyi with the cultivars Bergenia stracheyi 'Alba' and Bergenia stracheyi 'Afghanica'
  • Bergenia tianquanensis
  • Cultivation

    Bergenia are hardy plants that can grow in climates with extreme temperature ranges from about −35 °F (−37 °C) to 115 °F (46 °C). They prefer sun but will grow in shady areas as well. Plants can grow to about 24 in (61 cm) tall and 24 in (61 cm) wide. They do well in most soils, but moist, humus-rich soil is preferable. Exposure and dry soils tend to stunt growth, but can enhance the winter leaf colours. In areas with cold, strong winter winds, protection from the wind may be required. They are propagated by division or rooted rhizome sections.

    Bergenia crassifolia, Bergenia cordifolia, and various hybrids are often grown in gardens, with several cultivars selected.

    Pests and diseases

    Bergenia are robust plants and generally free of problems, although vine weevil adults readily eat the edges of the leaves, resulting in an indented, 'notched' outline which can detract from the appearance of the plant.

    Uses

    Bergenin, C-glycoside of 4-O-methyl gallic acid, and its O-demethylated derivative norbergenin, are chemical compounds and drugs of Ayurveda, commonly known as Paashaanbhed. They can be isolated from Bergenia ciliata and Bergenia ligulata and from rhizomes of Bergenia stracheyi. It shows a potent immunomodulatory effect.
