I know it is natural for Hellebores to turn green, but I purchased some white blooming Hellebores (Winters Bliss) in late winter and most of its blooms have already turned green (April 7) whereas my red/purple/blue hellebores still have most of their original color. Is this because the white bloomers bloom earlier? Does more or less sun (or anything else) have an impact on when they start turning green? The plants are still in pots and have been getting somewhat more light than the other Hellebores.

This is, actually, very common among many helebores. Mainly, the white and lavender varieties. They will, either, be the original color until the flower matures, or will have a very noticeable green tinge from the beginning. This article will explain some of the differences of a few cultivars: https://www.gardeningknowhow.com/ornamental/flowers/hellebore/different-hellebore-varieties.htm
Thank you. Very helpful. Could you recommend a particular cultivar that emphasizes blooms over foliage and maintains its color longer before turning green.
