A pyramid-shaped houseplant can easily become the focal point of a room or a table centerpiece. It's possible to buy a pyramid-shaped plant from specialty stores or florists, but they're often quite expensive. You can easily plant and train your own pyramid-shaped houseplant yourself and have the satisfaction of watching it grow into a living work of art.
Place gravel in the bottom of your flower pot. You don't need to purchase gravel; you can just go outside and find some. It should fill the bottom inch of your pot. This gravel helps ensure good drainage for your plant.
Fill the pot with potting soil. It should come within 2 inches of the top of the pot. Gently tap the pot against the ground to let the soil settle. Add more soil if necessary.
Using four bamboo skewers, make a pyramid with a square-shaped base. You can tie the tops of the skewers together with string or twist ties. Secure the bottoms of the skewer by inserting them into the potting soil in your pot. Make sure the pyramid feels secure.
Plant your vine seeds around the base of the pyramid according to the directions on the seed package. Water your seeds immediately after planting them, and continue to check the pot every day. Feel the soil, and if it feels wet, don't add any water to the pot. If the soil feels dry, however, thoroughly water the soil.
Once the vines begin to grow, train them to grow up the skewers by gently winding their coils around the bamboo. Once the vines begin to grow, they'll grow quickly, and you'll see the bamboo skewers becoming covered with your beautiful vines.
Feel free to trim back the vines when your pyramid begins to lose its shape. The vines will continue to be vigorous even if they're trimmed back. Expect your pyramid to last for one season.
