The Garden Flora
On this website plants are ordered alphabetically by their Latin name. This is done for practical reasons, that way plants within the same plant genus are grouped together, for example bluebells and hardy geraniums. When searching on-line for information about certain plants or ordering seed it's also very helpful to know the Latin name.
At the top of the page is a search window where you can search by common or Latin name. You can also search by colour, height etc.
