Sarah Farrell Angela Pascoe- check your hardiness zone map. Hosta & astilbe are shade loving plants and Hosta Hans for example is only hardy in zones 3-7. So start with knowing your zone and what kind of light areas of your yard gets throughout the day, select plants from there. Some online plant retailers have the option to search by zone etc.

woodsincity Sarah, Thank you! I have just put in a dwarf Crabapple ( ours in ME have Berries less than 1/2 in.) I can see that Hakone Grass might be very nice under my new tree!
