If you’ve ever wished your garden could come alive for Halloween, this project delivers.
Using a few PVC pipes and expanding foam, you can sculpt a massive carnivorous plant that looks both surreal and playful.
Its twisted shape and bold colors stand out beautifully among real foliage, especially when sunlight hits the glossy paint.
Materials Needed
- 1-inch PVC pipe (about 8 feet total)
- PVC elbows and joints
- Wire mesh or chicken wire for shaping the mouth
- Expanding spray foam (3-4 cans)
- Red, green, and black spray paint
- Plastic sheet or tarp for workspace protection
- Hot glue gun and glue sticks
- Foam board or plastic for teeth (cut into triangles)
- Optional: LED lights for glowing effect
Step-by-step Guide
Step 1: Create the curved stem using PVC pipe. Heat and bend it slightly to give a natural arching shape.
You now connect pieces with elbows and glue for stability.
Step 2: Form the plant’s head using chicken wire. Shape it into an open mouth, around 2 feet wide works great for proportion. Then attach it to the top of the PVC stem.
Step 3: Spray expanding foam over the wire mesh to create texture. Let it dry, then trim off any excess with a utility knife.
Step 4: Paint the mouth interior red and the outer layer green.
You can use black for shading and depth. Once dry, glue foam teeth around the edges.
Step 5: Anchor the PVC base into the ground or a large pot for support. Then add leaves or fake vines at the bottom to make it look rooted in place.
Tips:
You can tuck small LED lights inside the mouth for a glowing night effect, it makes the plant look like it’s ready to devour anything that dares to come close!
