'Botanical garden' is the name of the place where trees, shrubs and even non-woody annuals and perennials may be found growing. An older but still used term is 'arboretum', which specifies trees. Shrubs also may be found there if their mature height is 30 feet [9.144 meters], as small trees. But technically, shrubs should have their own exhibition space in a 'fructicetum', which comes from the Latin 'frutex'for 'shrub'.
Usually without trees, grass, or shrubs on a slope it will wash a lot of dirt down the slope when it rains. You can use ground cover or short growing grasses to help this while the larger trees or shrubs grow big enough to help with the problem.
