Plant identification can be intimidating and overwhelming when first starting out. I know when I first started learning about it, I had a hard time not feeling the totality of the information I felt was out of my grasp. Especially living in a time where smartphone apps will give you the answers you seek without sharing their process, it can feel like falling amongst crashing whitecaps of information without the security of a lifejacket. While those apps have their place, I found that learning from friends and teachers ways that plant beings can be differentiated made it feel more manageable for me, and therefore easier to identify the plant beings I chose to share with my students.
Your interaction with this article might vary depending on where you're at with plant identification, dear reader. They say the best way to solidify what you've learned is to teach (see: Each One Teach One), so teaching how to identify a couple plant beings once you feel highly secure in your identification is a great place to start.
If you are not confident in an identification, especially for an edible, don't teach it. No one likes to be misnamed, and we don't want to put anyone in harm's way. That doesn't mean that mistakes won't happen, and when they do, it's important to own up to them in a way that helps promote a culture of error. However, 1. It's better to be safe than sorry, and 2. It doesn't mean you can't teach how to approach plant identification. I believe that it's still beneficial for students to see that curiosity modeled, and they will learn from it. Your added step then, dear reader, would be to consult your local plant identification guide with your students to use the knowledge you discover together to find the name of the mystery plant being!
This is about internalizing an approach to gathering the information necessary to make a positive plant identification, with the added benefit of teaching how to approach plant identification without being an expert, and how to keep students engaged in the process.
Start from the Beginning: Gauge pre-existing knowledge
Check for familiarity with plant identification beforehand! There might be certain things that students already know, such as having a pre-existing relationship with a certain plant being or specific terminology. This will be helpful to know to cut out redundancies, which helps keep students engaged. Additionally, if a student is particularly knowledgeable, there is a potential opportunity for peer teaching! Information taught by peers is more likely to stick in the minds of other students since it capitalizes on pre-existing relationships.
Step 1: Ask students what they notice
When I start plant identification with students, I start big picture and survey the environment. What I mean by this is to understand the plant there first needs to be an understanding of the surrounding environment. Have students make observations about what they notice. Keep it simple. What kind of ecosystem are we in? Is the area disturbed? Is there obvious human interference? Are we near water? Are there any other plant beings they notice? This can be helpful information for making a positive identification later.
Next, I ask students for rapid-fire identifiers they notice off the bat for about 15 seconds. I believe this is a good way to gauge what details students are picking up on and what you might need to point out later during future steps. If students are noticing a particularly flashy identifier, such as a bright hue on a flower or a colorful berry, it shows that there's something about the plant that is grabbing their focus, and therefore more memorable. If students are noticing smaller details, like small spines on the underside of a Blackberry leaf, that's a good way to know they're starting to really pay attention to more minute identifiers.
Author's Note: These next 3 steps, I'm basically talking about 1. What I am noticing and 2. How I'm going about showing it. They are presented in a linear order, but the truth of the matter is that they are happening concurrently, which is inherently hard to represent due to the limitations of the written word. Order does not imply importance.
Step 2a: Go from Big to Small
I like to start by thinking about how different parts of the plant being connect to each other. How are the stem and leaves connected? How do the flowers or berries connect to the stem and leaves, if applicable? How is the plant being protecting themself?
After students point out some of the flashier identifiers, I want to explain others from broad to specific details of the plant being, without getting too specific. Students tend to remember the first and last things mentioned, or anything noteworthy. Keep it simple. I try to hover between 4 and 8 main identifiers, otherwise students are going to have a harder time.
This is also the time when a lot of terminology gets dropped that students might find in plant identification resources. I've learned these words over time, so it's important to strike a balance between helpful and overwhelming. I tend to stick mostly to words students are already likely to know, like "thorns" to describe pokey parts of the plant being. Since no one in this scenario is an expert, we don't need to get too into the weeds with details. As you grow your vocabulary around plant identification, use specific terminology with students who are showing a keen interest! (thorn vs. spine vs. prickle, for example). It's also a great chance to get students to make predictions based on words they already know the definitions of (opposite versus alternate, for example).
Step 2b: "Get on the plant's level"
An important part of plant identification is gathering the necessary information to make a positive identification. Moving throughout the identification process allows us to take in information from all over the plant. Crouching down, looking underneath, maybe even going on your tiptoes. The goal of this tip is to model how one physically interacts with the plant. Not just with sight, but touch and smell. If there are prickles on the stem, model to students how they can touch the plant with a stick or pencil gently, so they don't hurt themselves. If you know part of identifying Thimbleberry is by touching the leaves, show that. The easiest part about identifying lavender is by smelling it!
Step 2c: Narration
Whilst I am "getting on the plant's level" and moving through different parts of the plant, I will be narrating out loud what I'm noticing so students can get an idea of what questions they should be asking. This is a good moment to take in and highlight the identifiers that students have already pointed out, which draws students in because it makes them a part of the process. The goal of this tip is to model the kinds of identifiers that students should be looking for to make a positive identification.
Step 3: Draw Comparisons
I touched on this a bit in 2a, but what I'm thinking about when narrating my identification is making connections to students' pre-existing knowledge. One way is connecting identifiers to common shapes. Examples include "stinging nettles leaves are shaped like a heart", "the two bottom leaves of Salmonberry look like a butterfly", or connecting the word "serration" to a serrated knife, aka bread knife. You can also ask students if a particular identifier reminds them of anything to see what they come up with.
Step 4: Recap!
Have students summarize the information they just observed, either popcorn style to the group or pair share before sharing out (depending on timing and group preferences). This is not only a synthesizing opportunity for students, but it also functions as a check for understanding, which identifiers got across/were collectively remembered, and which weren't. This allows students the opportunity to commit this new information from short-term to long-term memory.
This would also be the moment that you would consult a plant identification guide if you were focusing on making observations, versus teaching how to identify a particular plant being. How to use a guide like this is beyond the scope of this article, but have students try to find the plant being in the guide with the information the group gathered. Even better if you designate a couple of them to work together on their identification.
Step 5: "What Plant is This?"
Allowing students to practice their recall makes it more likely that they will commit the information from short-term to long-term memory. After I've asked for identification from students, I also ask, "How do you know?" Let students pair share before asking them to share out, and let other students help if they get stuck!
Then keep reminding them! Give plenty of opportunities for students to remember. I find it's best when walking on trails, especially if they are particularly game-oriented (e.g., "You have five seconds to point to a Sword Fern" when resting during a hike from the Harbor).
Tip: connections to other lessons
It's a good idea to connect these identifications to previous activities and lessons as well. The goal is to create multiple connections in the memories of students that will make it more likely for them to make a positive identification from memory. Examples include Meet a Tree, Each One Teach One, or I have also connected identifications to art activities such as leaf rubbings/ prints!

Maps can also serve as a vehicle for connecting student memories to place. During a week of outdoor school, students will have many new exciting experiences, but since they are in a new place the memories may become fuzzy. When given the chance to connect the memories they are creating to place, by using a map of the place they have been exploring, students are able to engrain those memories deeper. One way that I do this with students is by creating a map on butcher paper that they can use throughout the week to document the paths we take and the memories we make along the way. At the end of the week, this map serves as an artifact of all the things the group has accomplished and as a reminder of the place we have built a strong connection with. This map creation as a team helps highlight the connection and relationship that the students have built with place over the course of one week. Using maps as a way to remind students of their place in an environment and of how they are connected to that environment is a great way to build a student sense of belonging and accomplishment in outdoor school.
