candida and marie boisselot can be confused. marie b is a more vigorous plant, less prone to fungal wilt. the main difference is that , in partial shade upon opening, a candida will have a VERY faint bluish blush and a marie b may have a VERY faint blush of pink. as the bloom matures and bleaches they come up to the same color. both have very large blooms. marie will be larger than candida within the first 3 years for most gardens, and a more reliable plant.
this is 08 marie b, showing a large bloom on a 4 year old plant
