About Elephant Ears Bergenia

Bergenia crassifolia · also called Elephant Ears Bergenia, Leather Bergenia · flowering

A robust evergreen perennial from Siberia and East Asia, bearing large, thick, spoon-shaped leathery leaves that develop reddish tints in autumn and winter. Nodding pink to purple-pink flowers appear from late winter through spring on stout red stems. Exceptionally tough — surviving to −40°C and thriving in shade, clay, and drought — making it an outstanding ground-cover perennial.

Cold limit: USDA 3–9 · RHS H7 (-40°C to 30°C)

Watch for — Frost damage to flowers: Late winter to early spring flowers can be caught by hard frosts, turning black. Foliage is unaffected. Protect emerging stems with fleece during frost warnings if early flowers are valued; otherwise simply cut back blackened spikes.
