Heartleaf Bergenia doesn't bloom at all

heartleaf bergenia. 2 years old, hasn't bloomed since I bought it. 1st year, was in pt. shade, 4 hrs of sun each morning, always-damp clay soil. Leaves would unfurl nicely and grow big and turn red all over plant, but no stalks & blooms. 2nd year, moved it to more shade. A mole burrowed through it in winter, but leaves still came up this spring. Right away, the leaves are shriveling & die. Is my soil bad for the plant? Help!
