Hey Darren, Roses need full sun to reach there full potential but lots of shrubs will tolerate partial shade. It will possibly be poor dry soil? If a mature cherry tree and another tree are growing there. I would steer clear of lavenders and roses if you are sure its partial shade, they wont thrive. I grow lots of Heuchera's so would definitely advocate them. Some ferns and foxgloves like dryish partial shade.
Definitetly dig in plenty of compost if it is really dry soil. Not alot of plants like full shade so consider raising the canopy on one or both of the trees or just remove any branchs that would allow more light to the area you want to plant up and that dont spoil the overall shape of the tree. Watch where the sun goes throughout the day and see if you can get more sunlight where you want it
