With the possible exception of not being overly fond of heavy clay soils (pretty typical in Georgia) and excessive soil acidity, they should be very easy for you to grow. I find most hellebores perform and flower best with at least some sun during the day - they are shade tolerant, not necessarily shade lovers.

The Royal Heritage strain would not necessarily be my first choice - I find the plants from this breeding program less vigorous than other x hybridus seed strains and with less distinctive coloring.
