The Morton Arboretum has a great resource for you to use with your classes when teaching plant material used in landscape design. Use the Tree and Plant Finder page of their website to help students select the right plant material for their landscape plan.
The website allows you to sort by
- plant type (tree, shrub, ground cover, etc)
- by hardiness zone
- by foliage (deciduous or evergreen)
- flower color
- height
- light exposure
- shape or form
- use in the landscape (windbreak, mass planting, etc)
