Latin Plant Names Explained (And What Do They Mean?) A Guide to Understanding Scientific Plant Names
NOTE: This article is a tutorial on how and why we use the scientific, or Latin, names for plants, especially for plant identification of food and medicinal herbs. Find out what some of the names mean, and how they relate to you!
Oh, those fancy Latin binomial plant names….Do you really need them? After all, can’t I just talk about elderberry and everyone knows what I mean, don’t they? Before I really understood these scientific plant names, I thought they may be just a little….I don’t know….overdone? But then….I had a light bulb moment…and it all happened because of elderberry.
And yes. We DO absolutely need these Latin names for proper identification and to help us choose the right herbs for out needs!
And…it’s important to know what they mean for a number of reasons.
I was talking with a friend on the phone many, many years ago, and she was asking about red elderberry. Way back then, nearly 30 years ago, I just thought elderberry was simply elderberry.
My dad used to take us foraging in the mountains in Southern Nevada as a young child, and I grew up thinking that what I know now is Sambucus cerulea was the only elderberry there was. That was elderberry, right? Aren’t they all the same, after all? That’s the child’s mind. And we all only ever called them “elderberry.”
And then let’s consider essential oils. When most people think of eucalyptus, they’re thinking of the most popular, Eucalyptus globulus. Well guess what? This species is one that isn’t safe for children under the age of 10 due to the high levels of 1,8 cineole it contains.
However, there’s another species of eucalyptus much better suited for young ones. If you know which one this is (Eucalytpus dives), then you can search out that species of essential oil and be much safer in its use with young ones.
Once I began studying botany and herbalism, and I realized….Oh. My. Gosh! These binomial names are REALLY important.
Another example, the red elderberry (Sambucus racemosa) is rather more toxic than other species of elder to humans. And, depending on the environment, Sambucus cerulea can be a very small shrub, only a couple of feet tall; or it can be a towering tree…knowing about the plant is vital, and this starts with proper identification, knowledge of the plant and its iterations….and of course, the scientific name.
Also, not all species of related plants have the same medicinal properties, either. This is another reason the Latin binomial is important. Sambucus (elderberry) species, although having similar medicinal properties, do have some differences. And this applies to plants in general, too.
Even nursery plants need to have the Latin binomial on them. I’ve seen plants labeled, “St. John’s wort” and no Latin name. Well, there are many species of Hypericum, and the only medicinal one is Hypericum perforatum. I’ve seen many a sad student realize they just purchased the wrong St. John’s wort.
Knowing which species of a plant a person is talking about is vital to making good choices, especially if you are foraging.
**NOTE: If you’re wondering specifically about elder, you can find out everything you need to know about foraging & identifying elder as well as my delicious elderberry syrup recipe here, if you like.
Now, I’m just using elderberry as an example.
We could apply this to any single plant genus and species. Understanding the Latin names as well as proper foraging and identification techniques is vital to being a good herbalist….unless you simply want to purchase your herbs, and that’s fine too.
But even if you are purchasing herbs, you still should understand exactly what you’re buying.

Latin Plant Names Explained: What Do They Mean?
All living things are placed in related groups so scientists can commonly refer to them the same way no matter where in the world the living thing lives.
You see, using Latin binomials (genus & species) is common scientific language spoken all over the world, and there is no doubt about what plant is being referred to when you are using the scientific name.
Plant classifications and organization start out with class, then moves on to order, then to family, genus, and species.
When a scientist first discovers a new plant, that plant is given a special name in Latin, depending on what family it falls into, its genus, and then it's species is usually a descriptor of some kind to make it easy to differentiate between other plants in the genus.
Because the plant's special name consists of two words (genus & species), it is known as a "binomial." The first name is capitalized, and the species name is not. Both are italicized and are often found in parentheses after the common name.
For example, I could refer to the elderberry bush down the hill, but what does that really mean? Is it the more toxic red elderberry? Or is it the highly medicinal black elderberry? Is it the lower growing shrub? Is it a towering tree?
Well, if I know its Latin name is Sambucus cerulea, then I know now that it is the blue elderberry that is native to the western part of North America and has similar medicinal qualities as the popular Sambucus nigra.
You can see that the Latin binomial classification of plants saves us a lot of headaches in identification!

The blue water lily: Nymphaea ceruleae (blue water lily) has the same species name as Sambucus cerulea (blue elderberry), yet they are completely different plants altogether. The genus is the primary category; the species names are descriptors. Cerulea means “blue.”
There's a little more to know about using Latin names:
The genus name CAN be referred to alone, and often is when we are talking about a group of plants. For example, I could say, Rosa spp. The Rosa tells us it is the Rose family, and the "spp" tells us there are multiple species.
The species name is NEVER referred to alone, because these are descriptors for a plant in a genera (plural for genus). There are all kinds of species descriptors. Let's talk about some of these common names for species.
So, Rosa canina is (I'm sure you guessed) a rose. It is actually a dog rose, hence the species name "canina," like canine. And Rosa rugosa is the name of another different species of rose. Rugosa means "wrinkled" or "rough."
It's kind of fun when you start understanding a little bit about Latin, which you will the longer you study your plants!
Let's talk about elderberry again. The genus for the elderberry plant is Sambucus.
Here are some different species of elderberry: Sambucus nigra, Sambucus cerulea, Sambucus racemosa and there are others.
Now let's look at what kind of plants these are in the same genus. Nigra means black, so Sambucus nigra is the black elderberry (really a very dark purple) we find naturally growing in the southeast United States and Europe.
Sambucus cerulea is the blue elderberry (which actually has a white yeast coating on the berries, making them look blue) and grows naturally in the mountain areas of the western part of North America. This plant has very similar medicinal properties as the black elderberry.
But now I want to talk about Sambucus racemosa. This is the red elderberry....and it is far more toxic to humans than other species of elder and really shouldn’t be used medicinally, in my opinion. Can you see how important the binomial system is when discussing plants?
Some herbalists are very persnickety about being sure to use the Latin name all the time. Others are more casual about it. Regardless, the Latin name system is very important and nails down the exact plant you wish to identify or discuss.
A Friendly, Simple Way to Understand Latin Plant Names
Plants are our friends, right?
Just think about learning the Latin names as though you are learning the name of a new friend. :-) Makes it more fun!
And there is one more thing I want to discuss, and this is the family name. The family name is a broader category under which the genus and species fall.
Let's talk about the beautiful rose again. The rose family is Rosaceae. This family is huge, and includes shrubs, trees, and everything in between.
So, Hawthorn, a wonderful tree with medicinal leaves and berries, has a genus name of Craetagus spp. But like the common rose, this tree is also in the rose family (Rosaceae). If we are talking about the common hawthorn, we would say: Craetagus monogyna; Rosaceae.
This shows us the genus, species, and also at the end, the family (you may also find it at the beginning of the name as well) . Some herbalists like to include the family name for further help in identification.
The Damask rose happens to be a hybrid. So you might see a little "x" in the name. This shows us it is a hybrid. It looks like this: Rosa x damascena; Rosaceae. So, now we know we are talking about the Damask Rose, in the Rose family, and that it is also a hybrid.
Pretty interesting, right?
Don't be worried about this, though. Those Latin names will start making more sense the more you get used to seeing them and perhaps even using them!

Here are Sambucus nigra, the black elderberry. A similar but still different plant than Sambucus cerulea, the blue elderberry.
Latin Names Explained
Here are some Latin name meanings to help you understand and identify the species of the plants—
These specifically refer to the species names, which again, are not capitalized. And by the way, you would never refer to a plant by only the species name. This is because other genera may share the same species name as a descriptor.
An example of this might be the blue water lily (Nymphaea cerulea) and the blue elderberry (Sambucus cerulea). Both are blue, but they are completely different plants. Just by saying the name, cerulea, you still have no idea what plant you are referring to. All you know is that it is blue!
Species names are simply descriptors that help to identify which species is being referred to and are often adjectives. Here are some examples (there are many, many more):
acaulis = stemless
alba = white
angustifolia = narrow-leafed
arvense = from the field
azurea = blue
cerulea also equals blue
canadensis = from Canada
chinensis = from China
digitata = leaves like a hand, with 5 lobes
foetida = stinky
lappa = thorn
latifolia = wide leaves
longiflora = long flowers
longifolia = long leaves
maculata = spotted
millefolia = many thousands of leaves
officinalis = with medicinal or herbal uses
pinnata = with pinnate leaves
purpurea = deep pink
rosea = rose pink
rubra = red
sativa = cultivated
spicata = spiked
viridis = green
vulgaris = common
These, of course, are just a few of the Latin names used to describe the specific species in a particular genus of plants. There are many, many others. But it’s fun to get to know these names!
So, if I look at the above list, and I see that Mentha spicata is actually spearmint, doesn’t that make sense? It’s a mint with spear-shaped or spiked leaves! While its famous counterpart, Mentha x piperita is actually peppermint! Two completely different mints called “Mentha,” but the species tells them apart.
I hope this little post cleared up this binomial topic a little bit for you. And if you are busy learning about herbs, I also hope you will spend a little time getting to know your new green besties whole names! :-)

Final Thoughts on Latin Plant Names and Being All Scientific
Did I talk you into getting to know your plants a little better? I sure hope so. It’s really wonderful to be able to see a binomial plant name, now, and know that it refers to the genus and the species. And when you also start realizing more about the families these plants fall into, identification of plants becomes a whole new world!
I personally never thought I’d be excited about learning Latin….but now I am. And I’m also rather grateful for the five years I spent learning Spanish! The Latin romance language (Spanish, Italian and others) have many roots that are very similar to the Latin.
Go forth and study! :-) Or, at least know the genus and species (first and last names) of the plants you love to interact with!
