You are an avid gardener, and love to have beautiful flowers in your garden. However, as you do research on these flowers, or want to buy some, you come across some names that seem all Latin or Green to you (and they may be, since these are the scientific names given to these flowers). So, for example,

Aconitum carmichaelii is actually Azure Monkshood
Ageratum houstonianum is Ageratum / Flossflower

There is this site that lists the common names and scientific names for plants. You can find a plant from either the common name or the scientific name at this valuable site in the University of Cornell site (link)
