Polly is right going to the Terra Nova site is a good idea , they list the growing conditions and other info for each plant.
Susan Georgia Peach has Villosa as part of it's parentage and it is rated as full sun - part shade . But it depends where you live full sun zone 5 and full sun zone 8 are not the same thing. By me boarder of zones 5 & 6 most can take quite a bit of sun.
