Glossary of Important Indoor Houseplant Words

Important Indoor Houseplant Words

If you have been around here for a while, you know I love me some plants.  I was a practicing landscape architect for eight years in a design firm.  And then I continued doing smaller freelance jobs on my own for about a year after that before starting my blog, Delineate Your Dwelling.

I have endless plant craft projects and even wrote an Indoor Houseplants ebook all about how to not kill the plants.  I also have numerous plant care posts on TONS of plants, like this Peperomia Plant Care.

Peperomia Care

Hopefully by now, you are in agreement – I love me some plants!  Today, I thought it would helpful to put together a list of indoor (and a few outdoor) plant words.  

I know what these words mean, I took Botany and Horticulture classes in college, but they may not make complete sense to someone who isn’t as plant crazed as myself.

I have broken them down in alphabetical order for your ease, I hope you enjoy and learn something new!
