Which of the following is NOT a common name associated with Bergenia?

Bergenia is a perennial plant native to Asia and is well-known for its large, thick leaves and clusters of pink to white flowers. Among its common names, "Pigsqueak" directly refers to the sound that the leaves produce when rubbed together, highlighting a distinctive characteristic of the plant. "False Spirea" is another name used for Bergenia that acknowledges its resemblance to certain spireas, even though they belong to different plant families.

In contrast, "Common Thrift" specifically refers to the plant known as Armeria maritima, which is different from Bergenia and is recognized for its tufts of grass-like leaves topped with round pink or white flower heads. "Jack Frost" is a cultivar name associated with the plant Brunnera macrophylla, commonly known as Siberian Bugloss or false forget-me-not. Thus, "Common Thrift" is not a name that relates to Bergenia, making it the correct choice in this context.
