Discussion
B. Mathew (1989b) noted that the cultivated Lewisia columbiana ‘Rosea’ is this variety. B. L. Davidson (2000) noted that the United States populations have pink to magenta petals, whereas the British Columbia populations have white to pale pink petals characteristic of the other varieties. Mathew questioned the assignment of the British Columbia plants to this variety.
