The roses are fine. They should be watered routinely the first year. K/O roses will eventually reach around 5-6' tall or taller unless they are pruned. (Best to prune them in the late winter.) K/O roses are typically drought tolerant.
The Gold Thread False Cypress (Chamaecyparis pisifera) will top out around 5-7' tall and 3-5' wide- unless its a dwarf variety or you keep it pruned down.
