Often, shade becomes much more of a factor in the home landscape over time. Those newly planted trees and large shrubs get big; and after 10 or 15 years, sunny areas are now in the shade. Because a landscape is really never finished, this provides an opportunity to replant with shade loving plants and create a new look in your yard.
There are different types of shade conditions created by buildings as well as large shrubs and trees. It’s always instructive to study a shady spot by identifying the overhead path of the sun during different parts of the day and during different seasons. (You may be surprised that some shady locations get some fairly strong early morning or late afternoon sun.) Find out what type of shade conditions you have. Is the area in deep shade, morning sun/afternoon shade or dappled shade? The deeper the shade, the more limited your plant choices will be.
