Understanding Botanical Names

201608010A.jpgIf you garden and want to communicate with other gardeners, common names just don’t cut the mustard. The same plant can have so many of them and they change all over the world, in fact even within the same language. I mean, if Americans and Brits can’t even agree on what plant the word daisy refers to (it’s Leucanthemum vulgaris or oxeye daisy for Americans and Bellis perennis or English daisy in Great Britain), how useful can a common name be?

Fortunately botanical names, also called Latin names, are universal. Although they may seem complicated at first, they aren’t as daunting as you may think, especially when you have picked up a bit of botanical Latin.

Each botanical name is composed of two parts, the genus name, which is shared among related plants and is a bit like a surname, and the epithet, which makes it clear exactly which plant is being mentioned. For example, there are many related plants in the genus Helianthus, but the epithet annuum indicates a specific species, Helinathus annuum, the common annual sunflower.

List of Botanical Epithets

Here are some of the more common botanical epithets. Note that the ending changes depending on the gender of the genus name, which is why the same stem can end in –is, -e, –us, -a, -um, etc.

How many of these do you already know or have you already figured out? You’ll be surprised!

Garden writer and blogger, author of 65 gardening books, lecturer and communicator, the Laidback Gardener, Larry Hodgson, passed away in October 2022. Known for his great generosity, his thoroughness and his sense of humor, he reached several generations of amateur and professional gardeners over his 40-year career. Thanks to his son, Mathieu Hodgson, and a team of contributors, laidbackgardener.blog will continue its mission of demystifying gardening and making it more accessible to all.
