June 2009- You mean I have to learn Latin??

Well, you don't actually have to learn Latin to be a gardener or to enjoy herbs and flowers, but knowing the botanical name of a plant, especially an herb, is very helpful. If you use herbs for cosmetic or medicinal purposes, knowing the botanical name can be a matter of safety.

All plants and animals, too, are classified by the binomial system. That is, each organism can be uniquely identified by 2 words- the genus and the species. The value of this system is that people who speak in different languages can be sure they are talking about the same plant, for instance, by using the genus and species name in what is now called "modern scientific" Latin. Coriandrum sativum is cilantro, coriander, Chinese parsley. As you can see there are several common names for the herb, and by using the botanical name, everyone knows exactly what plant we're discussing.

The Genus describes the group to which all the like plants belong. Mentha is the genus to which all true mints belong. Each mint has its unique species name.

Spearmint is Mentha spicata

Peppermint is Mentha x piperata.

The "x" indicates that this species is a hybrid or cross between two other mints. In the case of peppermint, it is a cross between M. spicata and M. aquatica. When discussing a particular genus, it is common practice to use simply the first letter of the genus so long as it is clear which genus is being referenced. If you see the "x" in a botanical name, seeds from that plant will likely not come true to type. So, beware anyone selling Peppermint Seeds!

How do you remember all those Latin names??, I'm often asked. It's like learning any names. You just learn them. In many instances the botanical name actually gives you a clue as to some of the characteristics of the plant itself.

For example: if you see a plant with the species name "alba", that means the flower will be white. Here is a short list of some other common colors found in the species name of various plants:

argenteus- silver, silvery
niger- black
coccineus- scarlet
rubens- red
azureus- sky blue
caeruleus- blue, dark blue
purpureus- purple
violaceus- violet
aureus- gold
luteus- yellow
sempervirens- always green
viridis- green

There are variations on the above words, but these are some very common ones.

Some of the words used for the species name indicate the shape of the leaf, fragrance or taste, markings or how the plant grows.

alternatus- leaves grow in an alternate pattern on the stem
cordatus- heart shaped
dentatus- toothed
erectus- upright
frutescens- shrubby
globosus- round
reptans- creeping
hirsutus- hairy
pubescens- downy
fulgens- shiny
concolor- evenly colored
variegatus- variegated
humilis- low growing
minor- small
scandens- climbing
tortuosus- meandering
verticalis- vertical

Let's look at a few herb names and see if we can decipher the common name from the Botanical one.

Artemisia vulgaris- OK, this is in the Artemisia genus, and it is known as the common or "vulgar" one. If you guessed "mugwort", you're right!

Mugwort

Mentha suaveolens- Mint (Mentha), sweet smelling is Apple Mint.

Apple Mint

Lavandula dentata- This lavender (Lavandula) has "dentate" or toothed leaves. It's also known as French Lavender.

French or toothed lavender

Ulmus rubra- Ulmus is the genus for Elm, and rubra means red or reddish. Slippery Elm does have sort of reddish bark.

Slippery Elm

Anethum graveolens- Anethum is the genus for Dill, and graveolens refers to its strong fragrance.
Dill

Trifolium pratense- This  time the  Genus also tells us about the plant. Trifolium means 3-leaved, pratense is from the meadow. It's Red Clover!

Pronunciation is sometimes an obstacle to feeling comfortable with botanical names. No one wants to embarrass themselves in front of another. Just remember that the names are not Latin, but rather 'latinized.' Most people pronounce latinized words as they speak their own language: just by sounding out the syllables.

When you learn a little bit about the world of the botanical names of plants, you learn a lot about their characteristics, behavior, time of bloom, leaf markings and more. Don't be afraid of the botanical names of your plants. Learn to read them and know you're learning more about the herbs and plants we love.

For more information about the botanical names of plants, there is a book called A Gardener's Latin from the Editors of Country Living Gardener Magazine.
