Let’s Learn Latin!

As Cabin Fever (or whatever is worse than Cabin Fever) and another foot of snow falls heavier down upon us, it ushers in the time of year where otherwise ridiculous ideas for blog posts suddenly sound amazing. This is how a primer on Latin landed in front of you. I’m sorry!

…   …   …   …

I’ve never been forced to learn botanical/horticultural Latin, that was never a part of my collegiate education nor my Master Gardener training. I know a select few plant names in full Latin, mostly because of Gardener’s World if I’m being honest. But I do not have a practical, functional understanding of the language for it to be in any way useful. Let’s change that!

Now, before you run away screaming, I’m not trying to actually learn Latin. I just want to see if we can all learn some root words that will help us better understand things about the plants. You see, on Gardener’s Question Time (GQT) James Wong (who clearly DOES know his Latin) will chime in about certain plants- using their Latin names- and be all “well this means its golden and was found in China” or “well that means it grows tall and has blue-green foliage”. That’s the sort of thing that is practical knowledge and what I’m hoping to learn.

Are you with me?


This can apply to foliage or flowers, but is very helpful for when flowers aren’t present and/or plant tags are lacking.

From the South– Australis (ex: Baptisia australis, aka Blue False Indigo)
Perisan– Persicaria (Ex: Fritillaria persica, aka Persian Lily)

Honorable Mentions:

This is a funny header because these are plants that honor their Horticultural parents or famous naturalists in their name- so, honorable mentions. Get it? I crack myself up… This information won’t clue you in to any plant characteristics, but you do see them often enough that they warrant listing.

Thunbergii– Carl Peter Thunberg (ex: Berberis thunbergii, aka Japanese Barberry)
Wilsonii– E. H. Wilson, noted plant collector (ex: Magnolia wilsonii, aka Wilson’s Magnolia)
Sargentii– Charles S. Sargent (ex: Prunus sargentii, aka Sargent Cherry)
Jackmanii– George Jackman, English Clematis breeder (ex: Clematis jackmanii)
Lamarckii– Chevalier de Lamarck (ex: Amelanchier lamarckii, aka Serviceberry or Juneberry)

Now, I certainly don’t expect to remember all of this and I’m not going to make myself flashcards in order to memorize it. But, I have found researching this so very helpful to see how many of the Latin words are easily identified by their English cousins. The few outliers are found frequently enough to remember. And, of course, we all (mostly) have smartphones now so if you are ever in a nursery and can’t decipher what the plant’s name is trying to tell you- well, its only a Google search away!

Beatus toparia!

  1. A very useful summary. Some I knew, some I did not. I’ve learned the latin names of plants mainly from reading books and catalogs. Sometimes those latin specific names can be a little misleading. Helianthus occidentalis goes no further west than Kansas and as far east as New Jersey. But I suppose it was all occidental to the European settlers.
