Online Plant Databases | Canada & United States

Finding the Plant Information You Need

One of the most comical (and sometimes frustrating) communication problems in the online gardening world starts with the use of common plant names instead of the scientific ones. We all do it—since they are much easier to remember and say—but the mayhem happens when we’re using the same word but not referring to the same plant species. Zoink!

Not that this is going to solve that problem (I’m an Empress, not a magician), but it is helpful to toss in the scientific name early in the conversation to ensure we are speaking the same language and talking about the same thing.

The other problem plaguing the garden world is websites who make up gardeing advice to try and gain viral traffic. Bottom line, gardening is not magic: and there are far too many garden myths circulating out there.

Some of these databases (listed below) are helpful for identifying specific species and cultivars. There are also resources for identifying weeds and learning about invasive species. Every growing zone faces struggles and it is important to know which plants to avoid and encourage in your area.

I have listed some main databases I rely on for Canada and the United States. If you are looking for something specific to your region (there are hundreds more online), university extension offices (link below) are a great place to start. If they do not have the information you need, they can often direct you to someone who can.

This said, there are not perfect sources for factual information—in gardening or anything. Do you homework, be skeptical, question everything!—and happy gardening.

Photograph the plant with your phone. App (does its best to) identify it.
I’ve tested a few of these apps and this one performed best for me.
