Certain ornamental plants share visual traits with cannabis, leading to frequent misidentification. If you are searching for plants that look like marijuanas, you probably want to avoid a costly mistake or simply enjoy the aesthetic without the legal hassle. This guide covers the most common lookalikes, how to tell them apart, and what to do if you find one in your garden.
Many gardeners panic when they see a familiar leaf shape. But the truth is, dozens of common species have similar serrated leaves and tall, branching growth habits. Let’s clear up the confusion right now.
Why Do Some Plants Mimic Cannabis?
Plants evolve to survive, not to trick you. However, certain environmental conditions push different species into similar shapes. The palmate leaf structure (where leaflets radiate from one point) is efficient for catching light in many climates. That is why you see it in hemp, Japanese maple, and even some weeds.
Another reason is simple coincidence. The “weed” look is just a successful design for fast-growing annuals. When you plant something that grows tall quickly with big leaves, it will naturally resemble other fast-growing plants.
Here is a quick fact: True cannabis has a very distinct, skinny leaflet shape. Most lookalikes have wider, rounder, or thicker leaflets. Learning that one difference solves half your problems.
Plants That Look Like Marijuanas
This section is your main field guide. We will break down the most common culprits you might find in a nursery, a park, or your own backyard. Remember, none of these plants contain THC, so they are completely legal to grow.
Japanese Maple (Acer Palmatum)
This is the number one plant that gets mistaken for young cannabis. The leaves are deeply lobed and serrated, and the growth pattern is similar. However, Japanese maples are woody shrubs or trees, not soft-stemmed annuals.
- Stem: Woody and brown, not green and fibrous.
- Leaf color: Often red, purple, or burgundy, but some are green.
- Texture: Thicker, almost leathery feel compared to cannabis.
- Growth: Slow and structured, not fast and bushy.
If you see a plant with a single main trunk and branches that get thinner as they go up, it is likely a maple. Cannabis grows more like a bush with multiple main stalks from the ground.
Kentucky Coffeetree (Gymnocladus Dioicus)
This tree is a less common but very convincing lookalike, especially when it is young. The leaves are bipinnate, meaning they have smaller leaflets along a central stem. The leaflets are pointed and have smooth edges, but the overall silhouette screams “cannabis” to the untrained eye.
The key difference is the leaf arrangement. Cannabis leaves are palmate (all from one point). The coffeetree leaves are arranged along a stem like a feather. Look for that central rachis (stem) to confirm it is not weed.
Texas Star Hibiscus (Hibiscus Coccineus)
This flowering plant has leaves that are divided into five to seven narrow, pointed lobes. They look incredibly similar to a sativa cannabis leaf. The big giveaway is the flower. This hibiscus produces a huge, bright red or white bloom that is unmistakable.
Even without the flower, the lobes are usually thinner and more uniform than cannabis. Also, the stems are often reddish at the base. If you see a tall plant with a single large flower at the top, it is definitely not marijuana.
Marsh Mallow (Althaea Officinalis)
Yes, the plant that gives marshmallows their name looks a bit like weed. It has soft, lobed leaves that are fuzzy to the touch. Cannabis leaves are not fuzzy; they are slightly rough but not hairy.
This plant grows in wet areas and produces pale pink flowers. The leaves are also more rounded and less jagged than true cannabis. If you rub the leaf and feel velvet, it is marsh mallow.
Red Goosefoot (Oxybasis Rubra)
This is a common weed that pops up in gardens. It has arrow-shaped leaves that can look similar to young cannabis. However, the leaves are usually thicker and have a distinct mealy or powdery texture on the underside.
Red goosefoot also grows in a more upright, single-stem fashion. It rarely branches out like cannabis does. It is a nuisance weed, but it is harmless.
Sweet Wormwood (Artemisia Annua)
This plant is famous for its medicinal properties (anti-malarial). It has finely divided leaves that look like a fern, but from a distance, they can mimic the feathery look of some cannabis strains. The smell is the giveaway here.
Crush a leaf. Sweet wormwood smells like a strong, herbal, almost medicinal scent. Cannabis has a distinct skunky or piney aroma. If it smells like absinthe, it is wormwood.
Chaste Tree (Vitex Agnus-Castus)
This is a large shrub or small tree with palmate leaves that have five to seven leaflets. It is a very common ornamental plant in warmer climates. The leaves are narrower than Japanese maple but wider than true cannabis.
The easiest way to identify this is by the flower spikes. In late summer, it produces tall, purple or blue flower clusters that look nothing like cannabis. Also, the stems are square-shaped, a trait of the mint family, which cannabis is not.
How To Tell The Difference (Step-By-Step)
You don’t need to be a botanist to figure this out. You just need to look at a few specific parts of the plant. Use this checklist to avoid calling the police on a maple tree.
- Check the leaf base: Cannabis leaves attach to the main stem individually. Lookalikes like the coffeetree have leaves attached to a secondary stem.
- Feel the stem: Cannabis stems are hollow between nodes (where leaves attach) and have a fibrous texture. Most lookalikes have solid, woody, or square stems.
- Smell the leaf: Rub a leaf between your fingers. Cannabis has a strong, resinous, terpene-heavy smell. Most lookalikes smell like grass, nothing, or a mild floral scent.
- Look for hairs: True cannabis has tiny, crystal-like trichomes (hairs) on the leaves and stems, especially near the flowers. Lookalikes do not have these sticky crystals.
- Check the flowers: Cannabis flowers are clusters of small, greenish-white buds. Lookalikes usually have showy, colorful, or very distinct flowers.
If you follow those five steps, you will have a 99% accurate answer. The remaining 1% is usually solved by the smell test.
Why Misidentification Happens
It is not just you. Police and gardeners make this mistake all the time. The reason is that many plants share the same “leaf architecture” because they are distantly related or just evolved similarly. Also, young plants of many species look identical until they mature.
Another factor is the media. We are trained to recognize the iconic 7-fingered leaf. But that leaf shape is not exclusive to cannabis. It is a common shape in the plant kingdom. So, your brain is just doing pattern recognition on a very broad category.
What To Do If You Find A Lookalike
If you find a plant that looks like weed, do not panic. First, use the checklist above. If you are still unsure, take a photo and use a plant identification app. These apps are very accurate these days.
If you are a renter, you might want to let your landlord know you are growing a Japanese maple so they don’t get the wrong idea. If you are a homeowner, just enjoy the free ornamental plant. You can even prune it to look less “weedy” if it bothers you.
Remember, it is completely legal to grow all of these lookalikes. They are common landscaping plants. You are not breaking any laws by having them in your yard.
Common Mistakes To Avoid
Do not pull up a plant just because it looks suspicious. You might be destroying a valuable specimen. The Texas Star Hibiscus, for example, is a prized garden plant.
Do not call the authorities. They have better things to do than check on your chaste tree. If you are really worried, you can send a photo to your local agricultural extension office. They are the experts on local flora.
Do not try to smoke any of these plants. They are not psychoactive, and some, like the marsh mallow, are just going to taste like burnt grass. They might even be toxic if smoked in large quantities.
Legal Implications And Safety
While these plants are legal, you should still be careful. In some areas, having a plant that looks like cannabis can attract unwanted attention. If you live in a state where cannabis is illegal, it is best to keep these lookalikes away from the front of your house or street view.
You can plant them in the backyard or mix them with other non-similar plants to break up the visual pattern. This is not about hiding anything illegal; it is just about being a good neighbor and avoiding awkward conversations with the local police.
Also, be aware of “volunteer” plants. If you have bird feeders, you might get random seeds dropped in your yard. Some of these seeds might grow into plants that look like weed. You can just pull them up and toss them in the compost.
Frequently Asked Questions
Are there any plants that smell like marijuana?
Yes, some herbs like certain types of sage and basil can have a slightly skunky or spicy smell. However, the true “skunk” smell of cannabis is unique due to specific terpenes like myrcene and caryophyllene. If it smells like a skunk, it is likely actual cannabis.
Can I buy plants that look like marijuana?
Absolutely. Japanese maples and chaste trees are sold at almost every garden center. You can buy them online or in person. Just ask for a “palmate leaf” plant if you want that specific look.
Is it illegal to have a plant that looks like weed?
No. It is only illegal to have actual cannabis plants (where prohibited). Having a lookalike is not a crime, but it might cause a temporary misunderstanding. Keep your receipts or plant tags to prove what you bought.
What is the closest looking plant to marijuana?
The Texas Star Hibiscus and the Japanese Maple are the two closest lookalikes. They both have the classic palmate leaf structure with serrated edges. The main difference is the flower and the stem texture.
Will these plants get me high?
No. None of the plants listed in this article contain THC or CBD. They are purely ornamental or medicinal in other ways. Smoking them will only give you a headache and a bad taste.
