Early fall is a good time to put out perennials and shrubs. Make sure to research your plants and not rely on the plant tag for information on type of soil and light requirements as well as the ultimate size of the plant. For example, a plant tag may say "part to full sun" but not tell you it won't make as much color in part sun. Given your location, protection from full afternoon sun for the salvia makes sense. You'll need to research your specific hibiscus variety. Make sure to keep the plant watered going into winter dormancy.
