Sunset Plant Finder is a pretty cool tool. You can search plants by climate, type, and water/sun requirements. You can even search for houseplants (great for us city people). Then you get a list of potential plants with both the scientific and common name, plus info like care instructions. How much easier could it get?
The plant pictured above is the bellis perennis, or English Daisy. So pretty!
