For Plant Identification, Look At The Leaves First
For Plant Identification, Look At The Leaves First
If you are looking to identify a plant for yourself or others, here are a few things to keep in mind.
It’s now common practice to post photos of plants online and ask “the hive mind” for identification. We see such requests on the Cape Cod Gardening Facebook Group all the time. People are wonderfully generous about telling the person who posted what the plant is, but often times people guess based on a flower or fruit, and that identification, as well meaning as it was, isn’t necessarily accurate.
What’s the problem with an inaccurate ID? First of all, the person requesting information won’t have the right name and so won’t be able to find accurate information about the care of that plant. If they think it’s a perennial that can be cut to the ground, for example, and it’s actually a woody shrub that will die if it’s treated that way, they might kill their plant by cutting it back. Or if the plant is identified as a sun loving flower and it’s actually something that will do better in shade, the gardener might waste valuable time and energy planting it in the sun where it won’t do well. And heaven forbid if a plant that’s not edible is identified as something you can eat!
When you want to ID a plant, and think you might have a good idea, take a good look at the foliage. Then go to Google Image and type what you think the plant is there…compare the leaves of your plant or photo to the foliage you see in all the photos that come up. Do they look the same? Take a look at this example:
Don’t just compare the leaf shape, but look to see how those leaves are arranged on the stem. Leaves can be opposite each other, alternate along the stem, or whorled, which means that there are several around the stem coming out of the same leaf node. This is an important thing to know about shrub and tree identification. Here’s a couple of examples.
Of course Google Image isn’t going to ID a plant for you, and you have to have at least a starting idea about what the plant is. But by comparing what you think a plant might be to many photos, and looking at the foliage instead of the fruit and flowers, you’re likely to come closer to an accurate identification.
We frequently have customers come into the store asking for a plant to be identified. Sometimes we’re able to ID a plant right away, and sometimes the sample needs to be left for another staff member to confirm what the plant is. Note: if you bring in a plant sample, please have it in a plastic bag and make sure to drop it off when it’s fresh. Put your name, email and phone number on the bag so someone can get back to you.
